This study investigated the effects of an A. populnea hexanic extract on male rat reproductive systems. While generally safe, high doses of the Nova Lima extract reduced sperm count in the cauda epididymis after 14 days.

Area of Science:

  • Pharmacology
  • Toxicology
  • Reproductive Biology

Background:

  • A. populnea is a plant with traditional medicinal uses.
  • Research is needed to scientifically validate its effects on male reproductive health.

Purpose of the Study:

  • To evaluate the impact of A. populnea hexanic extract (HE) on the male reproductive system of rats.
  • To determine dose-dependent and time-dependent effects of the extract.

Main Methods:

  • Rats were treated with varying doses of A. populnea HE for 7 and 14 days.
  • Parameters assessed included body weight, organ weight, serum testosterone, sperm count and morphology, spermatogenesis, and cauda epididymis morphometrics.

Main Results:

  • No significant changes in body weight, absolute organ weight, serum testosterone, sperm counts, or sperm morphology were observed.

Related Experiment Videos

  • Spermatogenesis and cauda epididymis morphometrics remained unaffected.
  • A significant reduction in cauda epididymis sperm number was noted with the Nova Lima HE at 1 g/kg/day after 14 days.

    • Conclusions:

    • A. populnea HE generally does not adversely affect the male rat reproductive system at the tested doses and durations.
    • However, a specific extract (Nova Lima) at a high dose and prolonged exposure may impact sperm quantity.
