    Polyzoospermia, a condition of high sperm count, is linked to infertility and pregnancy loss. This study found that sperm-mucus interaction is likely not the cause of reduced fertility in men with polyzoospermia.

    Area of Science:

    • Reproductive Medicine
    • Andrology
    • Human Fertility

    Background:

    • Polyzoospermia, characterized by elevated sperm density, is often associated with diminished fertility and increased spontaneous abortion rates.
    • Understanding the underlying mechanisms of reproductive impairment in polyzoospermic men is crucial for effective infertility management.

    Purpose of the Study:

    • To investigate the incidence of polyzoospermia in infertile men.
    • To evaluate the reproductive outcomes, including pregnancy and abortion rates, in couples where the male partner has polyzoospermia.
    • To assess the role of sperm-mucus interaction in the reduced reproductive performance observed in polyzoospermic individuals.

    Main Methods:

    • Analysis of semen samples from 1374 infertile men to determine the incidence of polyzoospermia (sperm density > 250 x 10^6 cells/ml).

  • Prospective evaluation of 30 couples with male polyzoospermia to track spontaneous pregnancy and abortion rates.
  • Sperm penetration tests were conducted to assess the mucus-penetrating ability of sperm from polyzoospermic men.

    • Main Results:

    • An incidence of 4.2% for polyzoospermia was identified among the studied infertile men.
    • Couples with male polyzoospermia exhibited a spontaneous pregnancy rate of 38.7% and a spontaneous abortion rate of 25%.
    • Sperm penetration tests demonstrated normal mucus-penetrating ability in 29 out of 30 evaluated men.

    Conclusions:

    • Polyzoospermia occurs in a notable percentage of infertile men.
    • Despite high sperm counts, polyzoospermia is associated with reduced fertility and increased miscarriage rates.
    • The findings suggest that impaired sperm-mucus interaction is not the primary cause of reproductive issues in polyzoospermic men.
