Prolactinomas are usually associated with hypogonadotropic hypogonadism in both sexes. Clomiphene citrate is a well known selective estrogen receptor modulator that increases gonadotropin secretion via hypothalamic-pituitary action. We conducted a prospective, open label clinical trial of CC to evaluate its effects in reverting persistent HH in male patients with prolactinomas under dopaminergic agonist treatment.

Further study details as provided by Federal University of São Paulo:

Primary Outcome Measures:
  • assess the effects of CC treatment on testosterone levels in male patients with prolactinomas and persistent HH on dopaminergic agonist therapy [ Time Frame: 10 days, 4, 8 and 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Assess the effects of CC on sexual function, fertility, body composition, lipid and glucose metabolism, and quality of life were also evaluated.
