GH1 and polycystic ovary syndrome: For women close to, or over, 40 years of age, the use of growth hormone during ovarian stimulation is of advice, in order to improve the quantity and quality of oocytes recovered by ovarian stimulation (18).This same treatment is recommended for women with poorly developing endometrium (19) and for those in whom suboptimal oocyte and endometrial quality is due to polycystic ovarian disease (20).
