The effect of vasectomy on Sertoli cell function in rats

Investigative Urology
J D Harris, L I Lipshultz


In order to evaluate Sertoli cell function after vasectomy, we studied a group of 24 rats. Twelve animals underwent bilateral vasectomy and 12 control animals underwent a sham operation. At 3 and 8 weeks postvasectomy, six experimental and six control animals were sacrificed. Forty-eight hours before sacrifice, the efferent ducts of the testes of each animal were ligated to produce intratesticular androgen-binding protein (ABP) accumulation. Quantification of ABP was determined using a steady-state polyacrylamide gel electrophoresis system and a 2 nM 3H-dihydrotestosterone label. The ABP of the vasectomized and control animals was expressed as both picomoles per milligram of protein and picomoles per organ and was found to be 0.28 +/- 0.06 and 0.42 +/- 0.09 for the control and vasectomized animals at 3 weeks and 0.46 +/- 0.07 and 0.52 +/- 0.08 for similar groups at 8 weeks. Comparison of these values revealed no statistical significance. Vasectomy, therefore, had no demonstrable effect on Sertoli cell function in the rat and our findings support the concept that ligation of the vas does not result in long-term biochemical testicular damage in the experimental animal.

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.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Head And Neck Squamous Cell Carcinoma

Squamous cell carcinomas account for >90% of all tumors in the head and neck region. Head and neck squamous cell carcinoma incidence has increased dramatically recently with little improvement in patient outcomes. Here is the latest research on this aggressive malignancy.

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
