Insights

Quinine injection caused testicular damage and reduced sperm production in mice. However, most of these toxic effects on reproductive cells and tissues were reversible.

Area of Science:

  • Toxicology
  • Reproductive Biology
  • Histopathology

Background:

  • Quinine is an antimalarial drug with known side effects.
  • The impact of quinine on male reproductive parameters requires further investigation.

Purpose of the Study:

  • To evaluate the toxic effects of quinine on testicular morphology and spermatogenesis in BALB/c mice.
  • To determine the reversibility of quinine-induced testicular damage.

Main Methods:

  • BALB/c mice were administered a single maximum tolerable dose of quinine.
  • Testicular tissues were examined for morphological changes.
  • Spermatogenesis was assessed.
  • Sensitivity of different testicular cell types to quinine toxicity was evaluated.

Main Results:

  • Quinine injection induced significant morphological alterations in the testes.
  • Spermatogenesis was suppressed following quinine administration.
  • Gonocytes, interstitial endocrinocytes, and sustenocytes were identified as sensitive targets of quinine toxicity.
  • Most observed morphological changes were reversible.

Conclusions:

  • Quinine exhibits dose-dependent toxicity to the male reproductive system in mice.
  • The testes and spermatogenesis are susceptible to quinine's adverse effects.
  • The potential for recovery from quinine-induced testicular damage exists.
