PCOS అంటే ఏమిటి? Symptoms, Treatment & Pregnancy | Mother Hospitals

PCOS — Polycystic Ovary Syndrome — is one of the most common hormonal conditions affecting women of reproductive age, and it is also one of the most misunderstood. At Mother Hospitals & IVF Center, Boduppal, Dr. E. Prashanthi Reddy sees PCOS patients every single day. The most frequent question she hears: "Can I still get pregnant with PCOS?" The answer, in the vast majority of cases, is yes — and this guide explains exactly how.

What is PCOS / PCOD? How Common Is It?

PCOS (Polycystic Ovary Syndrome) — sometimes called PCOD (Polycystic Ovarian Disease) — is a hormonal disorder in which the ovaries produce excess androgens (male hormones), the menstrual cycle becomes irregular or absent, and multiple small, immature follicles (often called "cysts") develop on the ovaries without releasing an egg.

The condition is diagnosed when at least two of three criteria are present (Rotterdam criteria): irregular or infrequent ovulation, elevated androgen levels (blood test or clinical signs), and polycystic-appearing ovaries on ultrasound. It is not a single disease but a syndrome — meaning different women experience it differently.

In India, PCOS affects an estimated 15–20% of women of reproductive age, making it the most common endocrine disorder in this population. The prevalence appears to be rising, partly driven by sedentary lifestyles, processed diets, insulin resistance, and increasing stress levels among urban women.

PCOS Symptoms — What to Watch For

PCOS presents differently in different women. Some have all the classic symptoms; others have only one or two. The most common signs include:

• Irregular or absent periods: Cycles longer than 35 days, fewer than 8 periods per year, or complete absence of menstruation (amenorrhoea)
• Excess hair growth (hirsutism): Unwanted hair on the face (chin, upper lip), chest, abdomen, or inner thighs — caused by elevated androgen levels
• Acne: Often severe and persistent, particularly on the jawline, chin, and back — not responding to typical acne treatments
• Scalp hair thinning: Male-pattern hair loss or diffuse thinning at the crown, despite normal thyroid function
• Weight gain: Particularly around the abdomen — PCOS is strongly associated with insulin resistance, which promotes fat storage
• Darkening of skin: Acanthosis nigricans — a velvety dark discolouration at the neck, armpits, and under the breasts, indicating insulin resistance
• Difficulty conceiving: Because ovulation is infrequent or absent, natural conception can be challenging
• Mood changes: Anxiety and depression are significantly more common in women with PCOS — partly hormonal, partly the psychological burden of the condition

PCOS and Fertility — Can You Get Pregnant?

Yes — most women with PCOS can get pregnant, many without IVF. The key challenge is that PCOS disrupts ovulation, so the egg is not released at the right time (or at all) for natural conception. Once ovulation is restored — through lifestyle changes or medication — the uterus itself is typically normal and perfectly capable of supporting a pregnancy.

The treatment pathway for PCOS-related infertility is stepped and personalised at Mother Hospitals:

1. Lifestyle optimisation first: For women who are overweight, even a 5–10% reduction in body weight can restore ovulation in a significant proportion of PCOS cases — no medication needed. This is always the first recommendation.
2. Ovulation induction: Letrozole (first choice) or clomiphene citrate — oral tablets taken on Days 2–6 of the cycle to stimulate ovulation. Monitored with follicle tracking scans. Success rates per cycle are 15–25%.
3. Metformin: Improves insulin sensitivity, regularises periods, and enhances the response to ovulation-induction medications — especially helpful for women with insulin resistance.
4. IUI (Intrauterine Insemination): If ovulation induction alone does not achieve pregnancy after 3–4 cycles, IUI adds the benefit of placing sperm directly into the uterus at the time of ovulation.
5. IVF: Recommended when all above steps have not resulted in pregnancy, or when there is a co-existing male factor or tubal issue. PCOS patients often respond very well to IVF stimulation — producing multiple follicles — though careful monitoring is needed to prevent OHSS (ovarian hyperstimulation syndrome).

Lifestyle Changes for PCOS — What Actually Works

Lifestyle modification is not a soft option — it is genuinely the most powerful intervention for many PCOS patients. Here is what the evidence supports:

• Diet: A low-glycaemic index (low-GI) diet — rich in whole grains, vegetables, legumes, and lean protein — reduces insulin spikes and helps regulate hormones. Limit refined carbohydrates, sugary drinks, and processed foods. A Mediterranean-style diet is well-supported by clinical evidence for PCOS.
• Exercise: 150 minutes of moderate exercise per week (brisk walking, swimming, cycling) significantly improves insulin sensitivity in PCOS. Resistance training (weights) also helps by increasing muscle mass, which improves glucose metabolism.
• Sleep: Poor sleep worsens insulin resistance and raises cortisol — which further disrupts the hormonal axis. Prioritising 7–8 hours of quality sleep is a genuine fertility intervention for PCOS.
• Stress management: Chronic stress elevates cortisol, which interferes with LH pulsatility and ovulation. Yoga, mindfulness, or even regular walking outdoors can meaningfully reduce the stress-PCOS cycle.

Medical Treatment for PCOS

When lifestyle changes are insufficient, or when a patient is ready to actively pursue pregnancy, medical treatment is added. The most commonly used medications at Mother Hospitals for PCOS management include:

• Letrozole: Now the preferred first-line ovulation induction agent for PCOS, with higher live birth rates than clomiphene in large clinical trials
• Clomiphene citrate: A long-established oral ovulation induction agent — still effective, especially when letrozole is not tolerated
• Metformin: Not a fertility drug per se, but powerful at addressing the underlying insulin resistance that drives PCOS — often used alongside letrozole
• HMG injections: For monitored cycles where oral agents have not achieved ovulation — requires careful dose titration and frequent monitoring to prevent multiple pregnancy
• Laparoscopic ovarian drilling: A surgical option for PCOS unresponsive to medications — small punctures made in the ovary restore hormonal balance in a significant proportion of women

When Is IVF Needed for PCOS?

Not every woman with PCOS needs IVF. But it becomes the right choice in specific situations:

• Ovulation induction with letrozole or clomiphene has failed after 4–6 cycles
• IUI has not resulted in pregnancy after 3–4 attempts
• There is a co-existing factor — blocked tubes, significant male infertility, or uterine abnormality
• The patient is in her late 30s and wants to avoid additional delays

PCOS patients generally have an advantage in IVF: they have many follicles and typically produce more eggs than average. The important caution is OHSS (ovarian hyperstimulation syndrome) — and Dr. Prashanthi uses carefully calibrated stimulation protocols, including low-dose HMG and antagonist cycles, to minimise this risk while still achieving excellent egg numbers.
