[Modifications in spermatogenesis following antibiotic therapy]
Abstract:
Among eleven antibiotics with a high activity on the mitosis and on the meiosis of the seminal cells, gentamycin sulfate and cefuroxime are both the most aggressive. After 8, 15 or 30 days of treatment, a stop of the mitosis and of the meiosis, pyknosis and karyolysis are morphologically visualized in male adult rats. Histoenzymatic studies show first a decrease of the protein synthesis in the nuclei of the spermatogonia and of the spermatocytes, and second a decrease of the glucose metabolism in the spermatocytes layers. In other groups of rats treated, the sacrifice was performed after arrest of antibiotics, the morphological recuperation is slow after 8 days of treatment, none after 15 or 30 days. Histoenzymatic studies show that the recuperation of the protein metabolism is quicker than the glucose one. Arising after 8 days it can be complete after 15 to 30 days of rest. Some coincidences between these experimental works and some clinical disturbances in the fertility of men and animals after high doses of antibiotic may be pointed out.
Insights
Certain antibiotics, like gentamycin sulfate and cefuroxime, can harm male rat reproductive cells, impacting fertility. Recovery is possible but slow, especially after prolonged exposure.
Area of Science:
- Reproductive Toxicology
- Cell Biology
- Pharmacology
Context:
- Antibiotics are crucial for treating infections, but their potential impact on reproductive health requires thorough investigation.
- Male reproductive cells (spermatogonia and spermatocytes) are particularly sensitive to cytotoxic agents.
Purpose:
- To investigate the effects of specific antibiotics on male rat reproductive cell mitosis and meiosis.
- To assess the morphological and histoenzymatic changes in seminal cells following antibiotic treatment.
- To evaluate the potential for recovery of reproductive function after antibiotic cessation.
Summary:
- Gentamycin sulfate and cefuroxime demonstrated significant toxicity to male rat seminal cells, inhibiting mitosis and meiosis.
- Morphological alterations including pyknosis and karyolysis were observed, alongside decreased protein synthesis and glucose metabolism in reproductive cells.
- While recovery was observed after short-term treatment, prolonged exposure (15-30 days) resulted in limited or no morphological and metabolic recuperation.
Impact:
- Findings suggest a potential link between high-dose antibiotic use and male infertility in humans and animals.
- Highlights the need for careful consideration of antibiotic selection and duration in patients concerned about reproductive health.
- Provides a basis for further research into the mechanisms of antibiotic-induced reproductive toxicity and potential protective strategies.
