Growth hormone--non multum sed multa (quality, not quantity).
In view of the recent availability of recombinant human growth hormone (GH) and reports of its ability to augment ovulation induction by exogenous gonadotropins, we have surveyed the reproductive physiological role of GH and the family of polypeptides that mediate its action. The clinical studies using GH to improve ovulation induction, although achieving a significant reduction in exogenous gonadotropin administration, show only minor benefits in terms of attainment of pregnancy. An explanation for this phenomenon is suggested, and we provide guidelines for whom GH should be recommended.
