When gonadotrophin-stimulated IVF methods were being developed in the 1970s and 1980s, understanding of the physiology of FSH improved. In addition to its classic actions of stimulating aromatase activity and oestradiol secretion by ovarian granulosa

Follicular fluid steroid content and theca and granulosa cell steroidogenesis in pelvic congestion cystic ovaries were compared with steroidogenic function in both normal and polycystic ovaries. Ovaries were obtained at oophorectomy for benign gynaec

Anovulation in women with polycystic ovary syndrome (PCOS) is characterised by arrested growth of antral follicles. A relative lack of FSH may contribute to the persistence of anovulation but is unlikely, by itself, to be a major cause of it. Granulo

Polycystic ovary syndrome is the most common cause of anovulatory infertility. Anovulation in polycystic ovary syndrome is characterized by the failure of selection of a dominant follicle with arrest of follicle development at the 5-10 mm stage. In a

In experimental animal models, insulin-like growth factors (IGFs) have been found to be more potent stimulators of ovarian function than insulin. In human theca cells, however, insulin, IGF-I, and IGF-II have similar effects on androgen production. T

Several studies have now documented the existence of IGFBPs in follicular fluid and their correlation with the health of the follicle. In particular, increased levels of IGFBP-4 have been reported in androgen-dominant atretic follicles and those from

The presence of IGFs and their associated binding proteins (IGFBPs) in human follicular fluid is well documented. Furthermore, most of the constituents of the IGF system in follicular fluid have been found to vary, either in total amount or by proteo

The control of ovulation in mammalian species appears to be a highly robust process. The primary mechanism is believed to be competition amongst a group of developing follicles, mediated by a hormonal feedback loop involving in the first instance the

A number of putative paracrine factors are now thought to interact with FSH in the control of ovarian steroidogenesis. The relative importance of these factors remains to be determined, but the presence of the insulin-like growth factors and their bi
