title: Chronic ultra-low dose follicle-stimulating hormone regimen for patients with polycystic ovary syndrome: one click, one follicle, one pregnancy.
abstract: In the present study we demonstrate that using a weekly incremental dose as small as 8.3 IU of FSH in a chronic ultra low-dose step-up protocol for anovulatory polycystic ovary syndrome (PCOS) produces very good clinical results with an excellent safety profile. Although using a significantly lower incremental (16.6% of the initial dose) and total (622 +/- 286 IU) gonadotropin dose, compared with the widely used and accepted low-dose gonadotropins regimen, a clinical pregnancy rate (PR) of almost 30% per started cycle has been achieved with just one twin gestation and no case of even mild ovarian hyperstimulation syndrome (OHSS).
