Could a common ED drug boost fertility in PCOS?

This trial asks whether adding sildenafil citrate to the standard fertility drug clomiphene citrate can improve ovulation and pregnancy rates in women with polycystic ovary syndrome (PCOS) who have been trying to conceive for over two years. About 98 women aged 18–45 will be randomly assigned to receive either clomiphene alone or clomiphene plus sildenafil for 12 weeks. Researchers will track ovulation, pregnancy, and uterine lining thickness to see if the combination offers an advantage.
