Hormone profile in hyperprolactinemic infertile men.

S Mićić, R Dotlić, V Ilić

    Archives of Andrology
    |January 1, 1985
    PubMed
    Summary

    Hyperprolactinemia in infertile men disrupts the hypothalamopituitary-testicular axis, causing higher FSH and lower testosterone levels. This hormonal imbalance affects sperm production and Leydig cell function.

    Area of Science:

    • Reproductive Endocrinology
    • Andrology
    • Infertility Research

    Background:

    • Hyperprolactinemia, elevated prolactin levels, is associated with male infertility.
    • The impact of hyperprolactinemia on the hypothalamopituitary-testicular axis in infertile men requires further elucidation.

    Purpose of the Study:

    • To compare hormonal profiles (FSH, LH, prolactin, testosterone, estradiol) in infertile men with hyperprolactinemia versus infertile and fertile men with normal prolactin.
    • To investigate the relationship between prolactin levels and specific hormonal disturbances in infertile males.

    Main Methods:

    • Serum hormone levels (FSH, LH, prolactin, testosterone, estradiol) were measured.
    • Hormonal profiles of 46 infertile men with hyperprolactinemia were compared to 50 infertile and 30 fertile men with normal prolactin.

    Main Results:

    • Hyperprolactinemic men showed significantly higher FSH levels, indicating spermatogenic disturbance.
    • Elevated LH levels were observed in infertile men with prolactin > 1000 U/liter.
    • All hyperprolactinemic men had significantly lower testosterone levels; estradiol levels did not differ among groups.

    Conclusions:

    • Hyperprolactinemia in infertile men disrupts the hypothalamopituitary-testicular axis, affecting spermatogenesis and Leydig cell function.
    • Further research on prolactin's role in male reproductive failure is warranted.
