Article Synopsis
- Several maternal undernutrition models show that male offspring experience testicular development issues and compromised sperm production.
- In this study, male pups were raised in either normal or larger litters, and at 90 days old, were assessed for sexual behavior and various tissue analyses.
- Although the undernourished males had histological changes in their testes, including abnormal tubules and fewer Sertoli cells, their sperm quality and sexual behaviors remained unaffected.
Topiramate (TPM) is an antiepileptic drug used for treating epilepsy in children, and migraine in teenagers. In this context, preclinical studies with adult female rats observed reproductive system abnormalities following treatment with TPM. Additionally, exposure to endocrine disruptors during developmental plasticity periods, such as childhood and adolescence, may influence characteristics in the adult individual.

Main Methods: Rats were treated with TPM (41 mg/kg/day, gavage) or vehicle (CTR group) from the postnatal day (PND) 28 to 50. At PND 51 and 120 the rats were evaluated for: thoracic aorta reactivity to phenylephrine, in the presence (Endo+) or absence of endothelium (Endo-), to acetylcholine and to sodium nitroprusside (SNP), aortic thickness and endothelial nitric oxide synthase (eNOS) expression.
Aims: This study aimed to evaluate the short- and long-term adverse effects of blood pressure (BP), vascular endothelial function, and estrogen receptor (ERα and ERβ) modulation on endothelial function in female Wistar rats treated with topiramate (TPM), an antiepileptic drug, during the peripubertal period.
Materials And Methods: Female Wistar rats were treated with TPM (41 mg/kg) or water (CTR group) by gavage from postnatal day (PND) 28 to 50 (peripubertal phase). At the end of the treatment, the TPM and CTR rats were divided into two groups and evaluated after 24 h or from PND 85 (adulthood).
Context: Sulfasalazine (SAS) is a drug prescribed for pregnant and breastfeeding women with chronic inflammatory bowel diseases. SAS treatment induces transitory infertility in both adult men and male rats. Although SAS crosses the placenta and passes into maternal milk, the consequences of maternal SAS exposure on the reproductive development of male offspring needs further study.
