Reversible toxic effect of salicylazosulfapyridine on semen quality

Insights

Salicylazosulfapyridine treatment for chronic ulcerative colitis can negatively impact male fertility, causing poor semen quality. Stopping the medication often leads to significant semen improvements and restored fertility.

Area of Science:

  • Reproductive Medicine
  • Gastroenterology
  • Pharmacology

Background:

  • Chronic ulcerative colitis (CUC) is an inflammatory bowel disease.
  • Salicylazosulfapyridine is a common treatment for CUC.
  • Medications can impact male reproductive health.

Purpose of the Study:

  • To investigate the effect of salicylazosulfapyridine on semen quality in CUC patients.
  • To determine if observed semen abnormalities are reversible upon drug discontinuation.

Main Methods:

  • Analysis of semen parameters (motility, morphology) in six CUC patients undergoing salicylazosulfapyridine treatment.
  • Comparison of semen quality before and after drug cessation in select patients.

Main Results:

  • Patients exhibited overall poor semen parameters during treatment.
  • Significant abnormalities included reduced sperm motility and altered morphology, with a notable presence of megalo cells (3-8%).
  • Discontinuation of salicylazosulfapyridine led to dramatic semen quality improvement in three patients.

Conclusions:

  • Salicylazosulfapyridine may exert a reversible toxic effect on male reproductive parameters.
  • Cessation of salicylazosulfapyridine can restore semen quality and fertility in some patients.
  • Further research is warranted to elucidate the mechanisms of this drug-induced toxicity.

Spermatogenesis01:41

Spermatogenesis

Spermatogenesis is the process by which haploid sperm cells are produced in the male testes. It starts with stem cells located close to the outer rim of seminiferous tubules. These spermatogonial stem cells divide asymmetrically to give rise to additional stem cells (meaning that these structures “self-renew”), as well as sperm progenitors, called spermatocytes. Importantly, this method of asymmetric mitotic division maintains a population of spermatogonial stem cells in the male reproductive...

Aryldiazonium Salts to Azo Dyes: Diazo Coupling

The reaction of weakly electrophilic aryldiazonium (also called arenediazonium) salts with highly activated aromatic compounds leads to the formation of products with an —N=N— link, called an azo linkage. This reaction, presented in Figure 1, is known as diazo coupling and occurs without the loss of the nitrogen atoms of the aryldiazonium salt. Highly activated aromatic compounds such as phenols or arylamines favor the diazo coupling reaction. The coupling generally occurs at the para position.
Infertility in Males01:23

Infertility in Males

Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
