Ovarian responses to menopausal gonadotropins in groups of patients with differing basal growth hormone levels.

Abstract：

OBJECTIVE:To investigate the relationship between endogenous serum levels of human growth hormone (hGH) and ovarian response to human menopausal gonadotropins (hMG). DESIGN:Retrospective analysis of patient response to hMG. SETTING:Center for assisted reproductive technology. PATIENTS:Eighty women who had undergone controlled ovarian hyperstimulation with hMG. Basal levels of hGH in sera from 40 of these patients were less than 5.0 microIU/mL (low hGH), values for the remaining 40 were greater than 5.0 microIU/mL (high hGH). Levels of hGH in day 2 sera were analyzed against numbers of oocytes recovered in an additional 182 patients. MAIN OUTCOME MEASURES:Serum estradiol (E2) levels and numbers of oocytes recovered at oocyte pick-up. RESULTS:Average (+/- SE) levels of hGH in sera of high-hGH and low-hGH patients were 10.2 +/- 0.6 and 2.47 +/- 0.3 microIU/mL, respectively (P less than 0.05). Respective peripheral levels of insulin-like growth factor-I were 105.3 +/- 2.9 and 97.2 +/- 2.8 ng/mL. Levels of E2 in serum of high-hGH patients exceeded respective (P less than 0.05) low-hGH values throughout folliculogenesis, and more oocytes were recovered from high-hGH patients (8.1 +/- 0.9 versus 4.7 +/- 0.5 for low-hGH patients; P less than 0.05). Serum progesterone values did not differ. Higher day 2 hGH levels were associated with higher numbers of oocytes recovered after controlled ovarian hyperstimulation. CONCLUSIONS:The present findings indicate that endogenous hGH may augment gonadotropins during follicle recruitment and during multiple folliculogenesis in women. The phase of maximum ovarian sensitivity to hGH/gonadotropin synergism and the nature of synergism remain unclear.
