[Diet-induced obesity increases the apoptosis of testicular spermatogenic cells in pubertal male rats].

Objective: To investigate the effect of diet-induced obesity on the apoptosis of testicular spermatogenic cells in pubertal male rats.

Methods: Forty healthy male rats were equally and randomly divided into a control and a high-fat group, the former fed on normal diet, while the latter high-fat and high-calorie diet. The testes of the rats were harvested at the end of 10 weeks for detection of total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) in the peripheral blood with the automatic biochemical analyzer.
