Preparing for IVF — The 90-Day Optimisation Window

Oocyte folliculogenesis takes approximately 90 days from primordial follicle to ovulation. The lifestyle choices, nutritional intake and clinical optimisations made today directly influence the eggs retrieved three months from now. This page lays out the evidence-based pre-IVF preparation protocol followed at Balaji Horizon.

1. Why 90 days matter

Folliculogenesis — the development of an immature follicle into a mature ovulatory follicle — takes around 85–90 days. The follicles being recruited for your IVF stimulation today are responding to your current internal environment. Optimising that environment for 3 months before stimulation has measurable impact on oocyte quality, fertilisation rate and embryo development.

2. Weight optimisation

BMI in the 20–28 range supports evidence-based IVF outcomes. Overweight (BMI >30) and underweight (BMI <19) both reduce success. For overweight patients, even 5–10 percent weight loss restores ovulation, improves stimulation response and raises live birth rates. Crash dieting in the 3 months before stimulation is counterproductive; sustainable Mediterranean-pattern eating is the goal.

3. Smoking cessation — non-negotiable

Smoking accelerates ovarian aging. Smokers reach menopause 1–2 years earlier than non-smokers and have measurably worse IVF outcomes — live birth rates approximately 30 percent lower per cycle. Complete cessation 3 months pre-cycle is essential. Partner smoking also impairs sperm DNA integrity and should stop equally.

4. Alcohol moderation

Heavy alcohol (more than 7 standard units weekly) reduces IVF success by 20–30 percent. Modest intake is unlikely to substantially harm, but eliminating alcohol during stimulation and for both partners during pre-IVF optimisation is sensible. Partner alcohol consumption directly affects sperm DNA fragmentation.

5. Folate and key supplements

Folate 400–800 mcg daily starting 3 months pre-conception. Vitamin D — correct any deficiency (target serum level 30–50 ng/ml). Iodine adequacy critical for fetal brain development. Omega-3 (DHA 200–300 mg daily) from fatty fish or supplement. CoQ10 (200–600 mg daily) — emerging evidence for mitochondrial support in older oocytes and poor responders. Avoid proprietary “fertility blends” without evidence.

6. Sleep and circadian regularity

Chronic sleep deprivation disrupts reproductive hormones and impairs IVF outcomes. Aim for 7–8 hours nightly with consistent timing. Treating sleep apnoea (often coexisting with obesity) makes measurable difference. Avoid alcohol as sleep aid — it worsens architecture even when it speeds onset.

7. Exercise — moderate, not extreme

Moderate regular exercise (30–60 minutes most days) improves IVF outcomes through weight management, insulin sensitivity, mood and inflammation reduction. Excessive endurance exercise (over 7 hours of vigorous activity weekly) impairs fertility through HPA-axis suppression. Strength training plus cardio in balance is ideal.

8. Pre-cycle investigations

By the time stimulation starts, the following must be complete: full pelvic ultrasound with AFC, AMH, day 2–3 hormone profile (FSH, LH, estradiol, TSH, prolactin), HIV/HBV/HCV/VDRL for both partners, partner semen analysis (repeated if abnormal), HSG or saline-infusion sonography for tubal patency, vitamin D, thyroid antibodies, hemoglobinopathy screening. Genetic carrier screening in selected cases. Hysteroscopy if cavity assessment indicated.
