IVF may be the most viable treatment for couples with months or years of infertility. How well it works depends on your age, health, and the underlying causes of infertility. Among the many crucial stages of IVF, egg retrieval seems the most intimidating. In simple terms, it refers to egg collection.
After ovarian stimulation, the mature eggs are collected through a minimally invasive procedure called egg extraction. If you, too, are about to have your eggs retrieved at a fertility clinic, here’s your detailed guide that unfolds everything you should know about egg retrieval, including the procedure, why it is necessary, whether it’s painful, and associated risks, success, and recovery tips.
What Is IVF Egg Extraction?
Egg extraction, also called egg retrieval, oocyte retrieval, or ovum pick-up (OPU), is an integral part of the IVF cycle. It’s when the eggs, which become mature in your ovaries after they are stimulated with fertility medication, are extracted through a small, surgical procedure.
These eggs are kept in a regulated laboratory with sperm, allowing them to be fertilized and developed into embryos. It is then cultured for 3-5 days before being transferred into your uterus.
A common concern among women planning to undergo egg retrieval is that the eggs from future cycles are retrieved at once. Since multiple eggs are used up, it might deplete their ovarian reserve. Every month, your ovaries produce multiple follicles containing immature eggs. Eventually, only a single egg matures in an ovulatory cycle.
Your body reabsorbs the remaining follicles. During IVF, ovarian stimulation medications are used to mature and retrieve multiple eggs (the ones that your body would have discarded otherwise). So, it doesn’t deplete your egg count.
Why Egg Extraction Is Necessary for IVF
Egg retrieval is a mandatory step in IVF. Here’s why:
Fertilization Process: Without mature eggs, fertilization cannot take place. While sperm matter equally, eggs provide half of the genetic material for embryo development. After retrieval, these eggs are fertilized by sperm in a petri dish, in an embryology lab, where they are monitored round-the-clock.
Embryo Development: Not every egg matures, fertilizes, or implants successfully. Collecting multiple eggs during the retrieval stage means there’s a higher chance that at least one egg is mature and healthy enough to become an embryo.
Who Needs an IVF Egg Extraction Procedure?
If you are advised IVF, ICSI, or egg freezing, you will need egg retrieval. Let’s see when and who needs this IVF procedure.
Women with Blocked Fallopian Tubes
If both of your tubes are severely damaged or completely blocked, conception is nearly impossible. Your tubes are where sperm and egg meet to form an embryo, which travels down to the uterus and attaches itself to the uterine lining. Tubal blockage prevents sperm from penetrating the egg, making it impossible to conceive naturally.
IVF extraction becomes an ideal treatment choice for such cases, as it bypasses the tubes entirely. Instead of waiting for the eggs to be released into the tubes, they are collected directly from the ovaries after maturation.
Women with Ovulation Disorders
Unpredictable ovulation cycles, whether due to PCOS or hormonal imbalances that affect the thyroid gland or pituitary gland, can make pregnancy challenging. In normal circumstances, your ovary matures an egg, which is then picked up by one of the fallopian tubes.
If intercourse occurs during this period, there’s a good chance you may conceive (if your hormones and overall health are normal). In ovulation disorders, such as PCOS, the follicles may develop, but eggs do not mature and are not released every month. Without an egg, you can’t become pregnant.
Initially, fertility medications are used to stimulate your ovaries to mature multiple eggs, but if ovulation disorders exist with other reproductive health issues that make natural conception difficult, IVF may be the most reasonable treatment choice.
Women with Endometriosis
Endometriosis occurs when endometrial-like tissues start growing in places outside your uterus. This may affect the tubes, ovaries, and other pelvic structures. Endometriosis can create an inflammatory environment, making fertilization and implantation difficult. The condition can also affect your ovarian function and damage egg quality.
Sometimes, this abnormal tissue growth can distort or completely block the fallopian tubes, making natural conception impossible. Instead of trying continuously to get pregnant naturally, women are advised to opt for IVF, which allows experts to fertilize the egg outside the fallopian tubes, thus bypassing the major barriers created by the disease.
Women Facing Unexplained Infertility
Unexplained infertility is when all your test results appear normal, you have no tubal blockage, your uterus is in good shape, there are no signs of ovulation disorders or endometriosis, or no significant problem in your reproductive health that could interfere with conception.
This, however, doesn’t mean there’s no underlying issue. Sometimes, issues in sperm quality, embryo quality, or fertilization are not detected easily on routine tests. If ovulation induction or intrauterine insemination fail, a fertility expert may recommend IVF. After egg retrieval, the embryologist can observe the fertilization process and detect developmental issues during cell division.
Couples Undergoing ICSI Treatment
Intracytoplasmic Sperm Injection (ICSI) is part of a fertility treatment and is particularly advised for couples with severe male-factor infertility. If you have an extremely low sperm count, poor movement, or a large number of abnormally shaped sperm, ICSI might offer you the best chance at fertilization.
Unlike normal fertilization, a sperm cell is directly injected into a healthy, mature egg using advanced microscopic equipment. The technique increases the chances of fertilization.
Patients Planning Fertility Preservation
Egg extraction is not just for couples facing infertility, but it can be equally effective treatment for those who want to preserve their fertility. For example, women undergoing chemotherapy, radiation therapy, or other invasive treatments that can damage ovarian function in the long run can choose to freeze their eggs.
Likewise, those who aren’t ready to become pregnant yet but would want to have their biological children sometime in the future can preserve their fertility by freezing eggs. As egg quality declines with advancing maternal age, it makes sense to preserve healthy eggs at a young age and have them thawed and transferred later when you are ready to start a family.
How Does IVF Egg Extraction Work?
Egg collection might seem like a one-time, quick procedure, but a lot happens before the eggs are ready to be retrieved. This involves multiple visits to the fertility center, ovarian stimulation, and regular monitoring to track the follicular growth.
Even small changes in your ovarian response can affect the IVF outcome, which is why each step is planned carefully before egg retrieval is scheduled. Let’s understand how it works.
Initial Fertility Assessment
An IVF procedure begins with a thorough fertility evaluation, where your reproductive health is assessed using blood tests, hormone tests, and ultrasound scans. This gives your doctor a complete picture of your reproductive health.
Ultrasounds, for example, help detect uterine anomalies, ovarian cysts, fibroids, and endometriomas, all of which can interfere with your fertility. It also gives antral follicle count (AFC), the metric used to determine the number of follicles at the beginning of your menstrual cycle.
Depending on your infertility cause or pregnancy history, they may order additional tests, such as hysteroscopy, for a more detailed examination. Before egg retrieval, an AMH test is conducted to check your ovarian reserve.
Ovarian Stimulation Phase
The next step is ovarian stimulation — stimulating your ovaries to mature multiple eggs in a single cycle using hormonal injections. The medicines usually start on the second or third day of menstruation and are continued for the next 8-14 days.
Many patients feel comfortable having them at home, at scheduled times. How ovaries respond to fertility medication can vary between women, depending on the dosage, age, and ovarian health. Some may also need to take these shots for a longer duration.
During the stimulation phase, your fertility expert will schedule ultrasound tests, which shows follicle size and number. This is done through hormone tests and transvaginal ultrasound, allowing your doctor to adjust hormonal medication based on your ovarian response.
Trigger Injection
The most crucial stage of an IVF cycle is a trigger shot. It’s administered once the follicles have reached the ideal stage of development. Normally, your body produces luteinizing hormone (LH), which matures eggs, preparing them for release.
After ovarian stimulation in IVF, the trigger shot mimics the same procedure. Without this step, eggs can’t be retrieved because many will still be underdeveloped or immature.
Patients are advised to take the trigger shot 36 hours before egg retrieval is scheduled. The timings might seem a little strict, but a fertility expert carefully plans the entire procedure so that eggs reach maturity but are not released yet from the follicles. Your clinic will give you the exact date and time for taking the trigger shot.
Step-by-Step IVF Egg Extraction Procedure
Once the follicles are 17 to 20 mm in diameter and estradiol levels are properly raised, egg retrieval is scheduled. It’s natural to feel a little anxious before the day, but rest assured that you won’t feel any major discomfort during or after the procedure. Let’s see the step-by-step breakdown of what happens during the egg retrieval day.
-
Arrival at the Fertility Clinic
Your doctor will give detailed instructions on how to prepare and when to arrive at the clinic for egg collection. It’s advisable to be at the clinic at least 30 minutes early and avoid eating or drinking anything a few hours before the procedure.
Also ask your doctor about which medicines to continue and which to avoid on the procedure day. If you have opted for fresh embryo transfer, your partner’s sperm sample will be collected on the same day, so that it can be used for fertilization shortly after eggs are collected.
-
Administration of Sedation or Anesthesia
You won’t feel anything during the procedure. In most cases, the fertility expert administers short-acting anesthesia or sedates the patient, so they can be relaxed throughout the retrieval procedure. You will likely wake up in 10-15 minutes after it’s done.
-
Ultrasound-Guided Needle Aspiration
Egg retrieval is an ultrasound-guided procedure. Like in ovarian stimulation, a transvaginal ultrasound probe is used during egg retrieval to collect real-time pictures of the ovaries and the developing follicles inside them. Attached to the device is a fine aspiration needle, which is guided to the follicles with precision.
Once it’s there, the follicles are gently punctured, and the fluid with the eggs is aspirated one at a time. The procedure requires a great level of precision to avoid damaging blood vessels and healthy tissues in the surrounding area. Note that eggs are microscopic cells, which can’t be seen on ultrasounds. That’s why the entire fluid is aspirated and sent immediately to the lab, so the egg can be isolated and placed with the sperm in incubators.
-
Identification of Mature Eggs in the Laboratory
The aspirated follicles flow through the tube into special egg collection tubes. They are handed to an embryologist, who examines the follicular fluid under an advanced microscope.
Not all follicles contain mature eggs, which is why it’s normal to have more follicles but fewer mature eggs at the time of fertilization. Once identified and isolated, the healthy eggs are transferred to the culture medium, which resembles a woman’s womb-like environment.
-
Recovery After the Procedure
After the procedure, you are shifted into the recovery room. Your vitals, including blood pressure and heart rate, are continuously monitored. You will likely spend 1-2 hours here before being discharged. It’s normal to feel mild cramping or light spotting for some time. Many also experience bloating or abdominal fullness. The symptoms are temporary and usually settle in a few days.
Sedatives can temporarily affect your concentration. It’s advisable to bring a family member to drive you home after egg retrieval. The biggest part of the IVF is done here. You can go back home, rest, focus on hydration, and eat a normal, balanced diet. While you recover, the collected eggs are fertilized in the laboratory and cultured for the next 3-5 days.
How Long Does Egg Retrieval Take?
While IVF itself might last for several weeks, egg retrieval is a short procedure, taking around 15-30 minutes depending on the number of follicles aspirated. You may need to spend a couple of hours at the clinic, but this includes preparation and a post-surgical observation period, as well. The exact duration varies from one patient to another.
The higher the number of follicles in the ovaries, the longer the overall procedure may take. That’s because each follicle is approached individually and is carefully aspirated. The recovery timeline also varies, but most women are advised to start walking and gentle movements soon.
Is IVF Egg Extraction Painful?
No, the procedure itself is not painful, although mild discomfort during and after the procedure isn’t uncommon. Sedatives help keep you relaxed.
Egg retrieval might seem like a complicated surgery, but it’s fairly straightforward. Let’s see some common symptoms that women may experience after egg retrieval:
- Pelvic pressure
- Mild discomfort
- Menstrual cramps
- Spotting
- Fatigue
Severe pain is not usual and requires an immediate visit to your fertility specialist. Remember, the exact level of pain also varies based on your individual pain tolerance and whether you have any existing condition, such as endometriosis. You may also feel tired after egg retrieval, but that’s because of the sedatives and ovarian stimulation earlier.
Ovarian stimulation can cause the ovaries to become large during an IVF cycle, which can cause pressure in the lower abdomen. Gentle walking around the house or practicing light household chores can help relieve the bloating and pressure.
That said, you should steer clear of heavy lifting or physical tasks that can put unnecessary pressure on the abdomen. If you experience unbearable pain, vomiting, severe abdominal swelling, heavy vaginal bleeding, or breathing difficulties, see your fertility expert immediately.
What Happens After Egg Extraction?
Your IVF journey doesn’t end here. Many patients aren’t aware of what happens in the backend when they are recovering at home. Let’s understand what happens after your eggs are collected, identified, and isolated.
Fertilization Through IVF or ICSI
If your partner’s sperm count, motility, and morphology are within the normal range, your embryologist will likely place thousands of sperm cells near the mature eggs in a special petri dish. These are left for several hours, or sometimes overnight, for fertilization. A sperm cell naturally penetrates the egg.
If male-factor infertility is present or you have a history of failed IVF, an embryologist may use ICSI to boost the chances of fertilization. Either way, the gametes are left in an incubator undisturbed overnight. The next day, the doctor checks the number of mature eggs that are fertilized.
Embryo Development
After fertilization, the embryos are cultured for the next few days and are monitored regularly to see how they are growing. Most healthy embryos follow a standard growth pattern. At Australian Concept, we use MIRI time-lapse incubators, which allow our embryologists to watch developing embryos 24/7 without disturbing them.
On day 2 of culture, the embryo has two to four cells, which turn into six to eight cells on day 3. The embryo becomes a morula on day 4 and eventually becomes a blastocyst containing hundreds of cells and two important structures: the outer and the inner layer. The chances of implantation are higher if they are transferred at this stage.
Not all embryos develop at the same pace. Some may turn into blastocysts by day 5, while others may take an additional day or more.
Embryo Transfer Process
Embryo transfer may be scheduled shortly after the embryo culture, but that’s not the case for all. Your fertility doctor will carefully examine your hormone levels, uterine lining, and overall health before transferring healthy embryos into the uterus.
In some cases, embryos are frozen and used later, when your hormones and reproductive health are in optimal condition. Sometimes, it’s deliberately delayed so that your body gets enough time to heal from ovarian stimulation.
Embryo transfer is a simple, quick procedure. It doesn’t require anesthesia and is done on an outpatient basis. The fertility doctor transfers a single or more embryos into your uterus using a thin catheter, under ultrasound guidance.
Embryo Freezing Options
Embryo freezing has become an advanced yet common part of IVF treatment today. It provides you with the flexibility to have an embryo transferred when you are ready to conceive. The best part is that if your IVF cycle fails, you can have another frozen embryo transferred in subsequent IVF cycles, without having to undergo ovarian induction and egg retrieval all over again.
Eggs are frozen using a modern technique called vitrification. It allows rapid embryo freezing, preventing ice crystal formation. These eggs are thawed and transferred into your uterus later.
How Many Eggs Are Usually Retrieved?
The first question that many women ask after egg retrieval is “How many eggs did you collect”? Some may have fewer eggs retrieved, while others might have 20+ mature eggs. The numbers aren’t the only thing that decides the success rate of IVF.
It’s true that higher numbers of eggs retrieved during the procedure will increase the chances of pregnancy, but overall IVF success depends on factors beyond egg count. Egg quality, i.e., the number of mature eggs that have a high potential of turning into healthy embryos and implanting successfully, matters too.
Factors Affecting Egg Numbers
Even if the same treatment protocol is used for ovarian stimulation in two women, they may have varying numbers of eggs retrieved. There are a few factors that can affect the number of mature eggs your ovaries produce.
- Age: Ovarian reserve, along with egg quality, decline with age. Women in their 40s may have fewer mature eggs after ovarian stimulation compared to younger women with healthy ovarian reserve.
- Hormonal Response: Your ovarian response may not always be the same as your fertility expert predicted. That’s why regular monitoring during ovarian stimulation is essential. Not because it increases the egg count, but because it helps get more mature eggs without increasing the risk of ovarian hyperstimulation syndrome.
Remember, there’s no ideal egg count for IVF success. Women with only 5 eggs retrieved during egg collection can become pregnant, while those with 20 eggs may not conceive. The goal is collecting healthy, mature eggs with the highest implantation potential.
Rare Complications
Serious complications are rare after egg retrieval, especially if it’s performed at Australian Concept or another reputable fertility center. Still, like any surgical procedure, egg retrieval carries some degree of risk. Here are a few you must know about:
- Infection
- Heavy bleeding
- Injury to nearby organs
- Ovarian Hyperstimulation Syndrome (OHSS)
OHSS, particularly, is the most discussed yet less likely to affect women undergoing ovarian stimulation. It’s when your ovaries react strongly to the fertility drugs. They might swell and leak fluid into the abdominal cavity, or rarely, into the chest. Women with high estradiol levels, PCOS, or a high ovarian reserve are at an increased risk.
The risk is significantly reduced with modern IVF protocols. Fertility specialists follow personalized treatment protocols, adjusting the medication dosage and type based on the woman’s age, health, and risk factors. If needed, they may freeze one or all embryos, so your ovaries can heal before the embryos are transferred into the uterus.
IVF Egg Extraction Cost in Lahore
A single IVF cycle in Lahore can cost between Rs 830,000 and 970,000. Egg extraction is only a part of an IVF procedure. The entire cost includes other steps, hormonal injections, lab procedures, and hospital stay.
Cost can vary between clinics and is usually not the same for all couples undergoing IVF. Here’s a look at some factors that may influence the overall IVF cost.
- Medication: Fertility drugs requirement for ovarian stimulation might vary between women. The type, dosage, and how long the drug is needed are decided based on your ovarian function. Sometimes, the dosages and medication itself are adjusted in the middle of the treatment cycle.
- Monitoring Scans: Some women require fewer ultrasound scans, while others may need frequent scans with repeated blood tests. This can influence the total egg extraction cost.
- Laboratory Procedures: Lab procedures make up a significant portion of your IVF package. This includes sperm preparation, egg assessment, fertilization, embryo culture, embryo monitoring, embryo freezing, and, in selected cases, PGT-A test to detect chromosomal abnormalities.
- IVF vs ICSI: Treatment cost also depends on whether you need conventional IVF or ICSI. Since ICSI requires advanced equipment and specialized embryologists, it’s typically more expensive than IVF with natural fertilization.
Before your IVF treatment begins, ask your fertility expert to share the cost breakdown so that you can plan your finances accordingly. It’s important to know how much the treatment will cost, whether they offer installment plans, and whether additional procedures, such as ICSI or PGT-A, are billed separately.
Why Choose an Experienced IVF Center for Egg Retrieval in Lahore?
An important consideration when it comes to IVF egg extraction is the fertility center. Egg extraction may seem a relatively simple procedure, but as mentioned above, it’s a carefully planned step that requires perfect coordination between your fertility team and embryologists.
From personalized ovarian stimulation protocol to egg aspiration, even a small error in any of the steps can affect your IVF success rate. A renowned IVF center is not only equipped with modern fertility care solutions, but has a team committed to providing evidence-based care.
Importance of Advanced Embryology Labs
A well-equipped, modern embryology lab provides a controlled environment, regulated temperature, and monitoring tools that create real-time pictures of the developing embryo. They maintain strict control over air quality, humidity levels, temperature, ventilation, and other factors that influence the embryo’s development.
Experienced Fertility Specialists
Before egg retrieval, the fertility expert observes the ovarian response regularly. This helps them provide a balanced hormonal treatment, ensuring proper egg maturity yet reduced risk of OHSS. They also time the trigger shot, schedule egg retrieval, and collect eggs in a sterile tube with precision.
Patient Safety Protocols
IVF is not just about egg extraction and embryo transfer. Patients’ safety should be the doctor’s priority. An experienced fertility doctor tailors the entire treatment protocol to the patient’s unique case, their age, health, ovarian response, and fertility goals. Rather than following a standard IVF approach, they understand your medical history and ensure each step is tailored to your reproductive health needs.
Conclusion
Egg extraction might sound intimidating. For most patients, it’s because they don’t know what happens before and during the procedure. Each step is carefully planned, personalized, and executed by fertility experts.

FAQs
How many eggs are normally retrieved during IVF?
There’s no fixed egg count that’s retrieved during egg extraction. It depends on your ovarian reserve, age, and how your ovaries respond to fertility medicine.
Can egg retrieval damage the ovaries?
No, egg retrieval does not damage your ovaries or deplete your reserve.
Do I need general anesthesia?
Not necessarily. In many clinics, patients are given sedatives or short-acting anesthesia so they can be comfortable during egg retrieval.
Can I go to work the next day?
It depends on the kind of work. Strenuous physical tasks are usually avoided after egg retrieval, but if you have a desk job, you can resume work within 1-2 days.
What should I eat after egg retrieval?
Focus on a healthy protein-dense diet. Ensure proper hydration and add lots of veggies and fruits to your meals.
How soon are eggs fertilized after retrieval?
In most cases, eggs are fertilized on the same day, usually within a few hours after they are extracted.
What if no eggs are retrieved?
It’s uncommon, but possible. If no eggs are retrieved during an IVF cycle, your fertility expert will adjust the medication dosage or plan future treatments based on your ovarian function.
Can frozen eggs be used later?
Yes, frozen eggs can be thawed and used later.
How Is Egg Retrieval Performed During IVF?
Egg retrieval is performed using a transvaginal ultrasound, with a thin aspiration needle attached to the probe. This needle aspirates the follicles from your ovaries, one at a time.
What Should You Avoid After Egg Retrieval?
Any heavy lifting, strenuous physical tasks, and sexual intercourse should be avoided until your doctor gives the green light.
Is Egg Extraction for Freezing Painful?
Egg extraction for freezing is basically the same procedure as egg collection for fresh embryo transfer. It has the same side effects, i.e., mild cramping, spotting, bloating, and fatigue, and is usually not painful.
