Embarking on a journey with one of the best IVF treatment centres in Delhi, NCR, and Gurugram requires a clear understanding of the clinical steps involved. Successful IVF is a result of meticulous planning, starting from the very first days of your menstrual cycle.

1. The Foundation: Ovarian Stimulation

Ovarian stimulation is initiated on the 2nd or 3rd day of the menstrual cycle. Before starting, we perform baseline ultrasonography and biochemical tests to ensure the body is in the optimal state for down-regulation. The ideal baseline includes:

• Thin Endometrium: Measuring between 2–4 mm.
• Follicle Size: No follicles should be larger than 9 mm (ideal range is 2–9 mm).
• Hormone Levels: Serum E2 should be <25 pg/ml and LH should be <4–5 IU/L.

2. Stimulating Multiple Follicles

Unlike a natural cycle where only one dominant follicle is produced, IVF requires multiple enlarging follicles. To achieve this, Gonadotrophins (225 IU to 300 IU) are administered intramuscularly for 6–7 days. Follicular growth is then monitored every alternate day starting from Day 7.

3. The Trigger: Predicting Ovulation

By combining sonographic observation (Days 7–10) with serum estradiol hormone levels, we can accurately predict the time of ovulation. The “Trigger” injection (HCG, recombinant HCG, or GnRH agonists) is given when:

4. The Critical Window: Oocyte Retrieval

Timing oocyte retrieval is the most critical stage of the IVF cycle. Careful planning permits the optimal retrieval of mature eggs. If aspiration is done too early, the oocytes will be immature and fail to fertilize. If done too late, the eggs may be spontaneously released and lost in the peritoneal cavity.

Why Choose Talwar Fertility?

At Talwar Fertility & Child Health Centre, we specialize in personalized stimulation protocols. By closely monitoring hormone levels and follicular diameter, we ensure that every patient receives the precise timing required for a successful pregnancy outcome.

Polycystic Ovarian Syndrome (PCOS) is a complex hormonal condition, and Ultrasound remains one of the cornerstone criteria for its diagnosis. At Talwar Fertility & Child Health Centre, we use high-sensitivity Transvaginal Sonography (TVS) to identify polycystic ovaries in approximately 75% of women who present with clinical symptoms of PCOS.

What are Antral Follicles?

Antral follicles are small, fluid-filled sacs in the ovary (measuring 2-9 mm) that contain immature eggs. In a normal menstrual cycle, these follicles grow over 10-12 days until one “dominant” follicle is selected to release an egg. However, in PCOS, this selection process is often disrupted.

Diagnostic Ultrasound Criteria for PCOS

Medical guidelines for PCOS have evolved to become more precise. Here are the key ultrasound markers we look for:

Why Accuracy Matters

Identifying the exact nature of polycystic ovaries helps in tailoring fertility treatments. Whether it is ovulation induction or managing insulin resistance, a clear ultrasound mapping of the ovarian stroma and follicle distribution allows us to predict how your body will respond to medication.
