| Abstract: | Levels of follicle-stimulating hormone, luteinizing hormone and prolactin were evaluated in 52 cases of postpill amenorrhea at the Institute of Post Graduate Medical Education and Research, Calcutta, India. All 52 patients had experienced amenorrhea for one year since discontinuation of oral contraceptive therapy. The incidence of postpill amenorrhea was much higher in patients with histories of oligomenorrhea or irregular menstrual periods. No relationship was seen between the number of cycles of pills used and the incidence of postpill amenorrhea. The ratio of luteinizing hormone to follicle-stimulating hormone in all cases exceeded unity, indicating that postpill amenorrhea is a type of functional secondary amenorrhea. |
