This study investigated the long-term acceptability of a levonorgestrel-releasing intrauterine system (LNG-IUS) in 165 women after 6 and 36 months of use. Changes in menstrual bleeding pattern were experienced by 161 (98%) women, with a cessation or transient absence of menstruation occurring in...
The follicle-stimulating hormone (FSH) binding inhibitor (FSHBI) has been identified as one of the factors present in follicular fluid exerting autocrine/paracrine effects on FSH actions in the ovary. Our group has isolated FSHBI from human ovarian follicular fluid and deduced its partial amino...
