Objective: To describe the achievement of fertility in an infertile man with a resistant macroprolactinoma by using high-dose bromocriptine and a combination of human chorionic gonadotropin (hCG) and an aromatase inhibitor.
Methods: We present historical features and results of clinical, laboratory, and imaging evaluation in a man with secondary infertility attributable to a resistant macroprolactinoma.
Results: We report a case of macroprolactinoma in a 36-year-old infertile man who failed to attain a normal serum testosterone level and fertility with use of either bromocriptine or cabergoline treatment. Testosterone replacement or hCG therapy in this patient resulted in an increase in serum prolactin levels, which declined after discontinuation of this therapy. The combination of high doses of bromocriptine, hCG, and an aromatase inhibitor facilitated near-normalization of serum prolactin levels, shrinkage of the macroprolactinoma, recovery of serum testosterone levels, sexual function, and sperm count, and achievement of fertility.
Conclusion: An aromatase inhibitor may facilitate successful testosterone replacement therapy in male patients with prolactinoma.
