Follicular aspiration (oocyte retrieval) is a minimally invasive procedure performed as part of in vitro fertilization (IVF) to retrieve oocytes from the ovaries. This stage plays a critical role in assisted reproductive technologies, as the quality of the retrieved oocytes directly affects fertilization success and embryo implantation.
When is follicular aspiration performed?
The procedure is carried out after ovarian stimulation, when the follicles reach an optimal size (18–22 mm). Follicular aspiration is usually performed on days 12–14 of the menstrual cycle following administration of an ovulation trigger (hCG or gonadotropin-releasing hormone agonists).
How is follicular aspiration performed?
- Preparation. The patient is advised to refrain from food and fluids for 6–8 hours prior to the procedure.
- Anesthesia. Intravenous sedation is most commonly used to ensure comfort and pain-free conditions.
- Oocyte retrieval. Under ultrasound guidance, the physician inserts a fine needle through the vaginal wall and aspirates the contents of the follicles. The entire procedure typically takes 10–20 minutes.
- Laboratory assessment. Retrieved oocytes are transferred to the embryologist, who selects mature eggs suitable for fertilization.
- Recovery. Within 1–2 hours after the procedure, the patient may return home and usually resumes normal daily activities the following day.
Possible sensations after the procedure
- Mild lower abdominal discomfort, similar to menstrual pain.
- Minor spotting.
- Slight abdominal bloating related to hormonal stimulation.
Advantages of follicular aspiration
- Minimal invasiveness. The procedure is performed transvaginally without incisions, reducing the risk of complications.
- Rapid recovery. Most patients return to normal activity within a few hours.
- High efficiency. Enables retrieval of the maximum number of viable oocytes for IVF.
- Quality control. Laboratory selection of mature oocytes increases the likelihood of successful conception.
Possible complications
Although follicular aspiration is considered a safe procedure, rare complications may include:
- Ovarian hyperstimulation syndrome (OHSS). May occur due to an excessive response to hormonal stimulation.
- Infection. The procedure is performed under sterile conditions, but inflammatory complications are possible in immunocompromised patients.
- Bleeding. Minor spotting is considered normal; however, heavy bleeding requires immediate medical attention.
When should you consult a physician?
- If severe pain, high fever, heavy bleeding, or a sudden deterioration in well-being occurs after the procedure.
- If symptoms of ovarian hyperstimulation develop, including severe abdominal pain, nausea, vomiting, shortness of breath, or pronounced abdominal distension.
