Abstract
High tonic serum concentrations of luteinizing hormone (LH) in the follicular phase, frequently witnessed in polycystic ovary syndrome, have been associated with decreased reproductive function. Impaired rates of fertilization, conception and miscarriage are obtained when LH levels are high before oocytes are collected, during ovulation induction or in women with regular cycles. Conversely, treatment that decreases LH concentrations, such as gonadotrophin-releasing hormone analogue or laparoscopic ovarian puncture, eases induction of ovulation and pregnancy and improves miscarriage rates. Tonic hypersecretion of LH appears to induce premature oocyte maturation, causing the problems with fertilization and miscarriage.
