Insights

Diabetes causes seminal vesicle dysfunction through oxidative stress, impacting male reproduction. Antioxidants can help alleviate ejaculatory issues but do not fully restore fertility in diabetic rats.

Area of Science:

  • Reproductive Biology
  • Endocrinology
  • Diabetology

Background:

  • Diabetes mellitus is known to impair male reproductive health and sexual function.
  • Seminal vesicles (SVs) are crucial androgen-dependent organs for male reproduction, susceptible to metabolic disturbances.

Purpose of the Study:

  • To investigate the impact of diabetes on seminal vesicle structure and function in a rat model.
  • To evaluate the therapeutic potential of antioxidants in mitigating diabetes-induced SV dysfunction.

Main Methods:

  • Streptozotocin-induced diabetes model in rats.
  • Assessment of SV size, contractility, histology, oxidative stress markers (malondialdehyde, oxidative stress markers), and cleaved caspase-3.
  • Measurement of serum testosterone levels and evaluation of mating outcomes.

Main Results:

  • Diabetes led to smaller SVs, hypercontractility, histological damage, increased oxidative stress, and cleaved caspase-3 expression.
  • Diabetic rats exhibited reduced serum testosterone and failed to produce offspring.
  • Antioxidant treatment improved SV parameters but did not restore testosterone levels or reproductive success.

Conclusions:

  • Diabetes-induced oxidative stress significantly impairs seminal vesicle function and structure.
  • Antioxidants show promise as adjunctive therapy for diabetic ejaculatory disorders.
  • Antioxidants alone are insufficient to reverse diabetes-related infertility.
