PATIENCE AND PERSISTENCE: IS DURATION THE MISSING PIECE FOR TREATING POLYCYSTIC OVARIAN SYNDROME RESISTANCE?
This editorial discusses the strengths and weaknesses of an extended letrozole protocol for ovulation induction for patients with refractory PCOS undergoing IVF. The protocol involves extending the standard 5 mg letrozole protocol from 5 to 7 or 10 days, keeping the same letrozole dose, in women who did not respond after the initial 5 days of treatment. The editorial discusses limitations to the study, such as small sample size and the inability to analyze secondary outcomes, and study strengths, such as the potential to reduce financial barriers with this method by reducing the need for ovarian drilling.
