Treatment of PCOS with Anovulatory Infertility and No Other Infertility Factors
This protocol targets a clearly defined clinical situation: polycystic ovarian syndrome presenting as the sole driver of anovulatory infertility, with no other contributing infertility factors identified in either partner.
The patient has PCOS with documented anovulatory infertility. No other infertility factors are present. In this setting, ovulation induction is the primary therapeutic goal, and management follows a stepwise evidence-based pathway — starting with first-line oral agents before proceeding to more intensive second-line interventions.
Second-Line Approach — Partial Overview
When first-line oral ovulation induction has not achieved the desired result, second-line management in this scenario involves gonadotrophin-based therapy administered under specific monitoring conditions designed to support safe, targeted follicular development. The full regimen — including selection criteria, monitoring thresholds, adjunct options, and the surgical alternative — is detailed in the structured protocol.

- Letrozole should be considered first line pharmacological treatment for ovulation induction in women with PCOS with anovulatory infertility and no other infertility factors to improve ovulation, pregnancy and live birth rates.
- Gonadotrophins could be used as second line pharmacological agents in women with PCOS who have failed first line oral ovulation induction therapy and are anovulatory and infertile, with no other infertility factors.
- Gonadotrophins with the addition of metformin, could be used rather than gonadotrophin alone, in women with PCOS with anovulatory infertility, clomiphene citrate-resistance and no other infertility factors, to improve ovulation, pregnancy and live birth rates.
- Either gonadotrophins or laparoscopic ovarian surgery could be used in women with PCOS with anovulatory infertility, clomiphene citrate-resistance and no other infertility factors, following counselling on benefits and risks of each therapy.
- Laparoscopic ovarian surgery could be second line therapy for women with PCOS, who are clomiphene citrate resistant, with anovulatory infertility and no other infertility factors.
