Abstract:
With the introduction of Highly Active Antiretroviral Therapy (HAART), there has been drastic decline in morbidity and mortality associated with HIV/AIDS. However, many patients experience adverse drug reactions perhaps due to the inherent toxic nature of HAART. The possible toxic effect of HAART (combination ARVs) on reproduction and sexual dysfunction in seropositive HIV patients remains a subject of intense research. This study was designed to investigate the toxic effects of HAART on the reproductive hormones and organs of male and female rats. Sexually mature adult male and female rats were administered therapeutic doses of single and combination antiretroviral drugs for 48 days and thereafter sacrificed under anaesthesia. Morphological and histopathological examination of the testes and ovaries were carried out. Serum biochemical assay, semen quality analysis and hormonal assays were also conducted using standard methods. Results show significant (p < 0.05) reductions in the weight of testes and epididymis across all groups versus control; sperm count and motility were also significantly reduced in the test groups while hormonal analysis in males revealed significant reductions in LH, FSH and Testosterone. In the females, there was a significant (p < 0.05) reduction in the number of ovarian follicles, prolactin, estrogen and progesterone. We thus conclude that the administration of single and combined antiretroviral drugs have potential reproductive toxic effects.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Overview of the Reproductive System
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...
