    Summary

    Elevated prolactin (PRL) levels are common in women with menstrual irregularities like amenorrhea and oligomenorrhea. Higher PRL levels correlate with greater menstrual disturbance, but not necessarily galactorrhea.

    Area of Science:

    • Endocrinology
    • Reproductive Medicine
    • Gynecology

    Background:

    • Menstrual irregularities such as amenorrhea and oligomenorrhea affect many women.
    • Hyperprolactinemia, elevated prolactin levels, is a potential cause of these disturbances.
    • Galactorrhea can be associated with hyperprolactinemia.

    Purpose of the Study:

    • To investigate the relationship between prolactin levels and menstrual cycle disorders.
    • To assess the prevalence of elevated prolactin in women with amenorrhea, oligomenorrhea, and normal menses.
    • To explore associations between prolactin, galactorrhea, and luteal phase function.

    Main Methods:

    • Systematic measurement of serum prolactin (PRL) and progesterone.
    • Study included 190 infertile women over 34 months.

  • Hormonal assays performed on patients with amenorrhea, oligomenorrhea, galactorrhea, and normal cycles.

    • Main Results:

    • Fifty-five percent of amenorrheic patients and 37% of oligomenorrheic patients had elevated PRL.
    • Only 9% of women with normal menses showed elevated PRL.
    • Mean PRL levels increased with the severity of menstrual disturbance, independent of galactorrhea.

    Conclusions:

    • Elevated prolactin is significantly associated with menstrual irregularities, particularly amenorrhea and oligomenorrhea.
    • Hyperprolactinemia is a key factor in menstrual dysfunction among infertile women.
    • Short luteal phase was the most common ovarian dysfunction linked to elevated PRL in women with regular cycles.
