Hyperprolactinemia and sexual disorders in men

Area of Science:

• Endocrinology
• Urology
• Sexual Medicine

Background:

• Sexual dysfunction, including impotence, ejaculatory incompetence, and inhibited sexual desire, affects numerous men.
• Endocrine abnormalities can contribute to male sexual health issues.

Purpose of the Study:

• To investigate the prevalence of hyperprolactinemia in men seeking treatment for sexual dysfunction.
• To determine the impact of elevated prolactin levels on sexual function and testosterone levels.

Main Methods:

• Endocrine screening was performed on 136 men presenting with sexual disorders.
• Serum prolactin and testosterone levels were measured.
• Men with hyperprolactinemia were further evaluated for pituitary adenomas.

Main Results:

• 8.1% of men (11 out of 136) were hyperprolactinemic.
• Eight men with markedly elevated prolactin and subnormal testosterone were diagnosed with prolactin-secreting pituitary adenomas.
• Psychotherapy showed partial improvement, but normalization of sexual function required prolactin reduction.

Conclusions:

• Hyperprolactinemia, often due to pituitary adenomas, is a potential cause of sexual dysfunction in men.
• Routine measurement of prolactin levels is recommended for men with sexual disorders and low testosterone.
• Treatment targeting prolactin reduction is crucial for restoring sexual function.
