Pcos And Fertility Statistics

PCOS affects 15 to 18 percent of reproductive age women and is linked to a 2 to 3 fold higher risk of type 2 diabetes and a higher miscarriage likelihood, while fertility concerns sit within a broader infertility backdrop of about 10 to 15 percent of couples worldwide. This page pulls together current PCOS fertility benchmarks such as letrozole first line guideline preference and clinic relevant outcomes like 22 to 30 percent pregnancy per cycle with clomiphene and modern OHSS prevention with GnRH antagonists, so you can see what changes when insulin resistance, ovulation, and treatment strategy collide.

PCOS affects about 15 to 18 percent of reproductive age women, yet it is also tangled up in the fertility problems many couples face worldwide, where infertility affects roughly 10 to 15 percent of couples. The link is not just irregular periods and delayed conception, but also measurable metabolic shifts like a 2 to 3 fold higher type 2 diabetes risk, plus pregnancy and treatment outcomes that vary widely by approach. Here is what the latest pooled estimates and real-world trial results add up to when you connect PCOS, ovulation, and infertility across both biology and clinical care.
