Influence of alcohol on the reproductive system of the male rat

International Journal of Fertility
R W Klassen, T V Persaud


Twelve male rats were treated with alcohol by an oral self administration technique. The testes, epididymides, seminal vesicles, kidneys, spleen, and liver were recovered from each animal. All organs were weighed and prepared for histological studies. Organs from experimental animals, with the exception of the liver, weighed significantly less than the corresponding controls. The testes of alcohol-treated animals revealed the following changes: thickened capsule, atrophic seminiferous tubules and damaged germinal epithelium, in addition to multinucleated giant cells, fragmented spermatozoa, and desquamated spermatocytes in the lumen of the tubules. Atrophic ductules containing very few spermatozoa were observed in the epididymides of these animals. The seminal vesicles were small and lined by degenerated epithelium. The serum testosterone levels were significantly reduced in alcohol-treated animals, compared to the controls. The present investigation indicates that alcohol adversely affects spermatogenesis and testicular function.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
