[Effect of Guilu Taohong Formula on semen quality and spermatogenic cell apoptosis in a varicocele model of rats].
Objective: To observe the effect of Guilu Taohong Formula on semen quality in varicocele (VC) models of rats, and to explore its possible mechanism.
Methods: Forty-eight male SD rats were randomly divided into four groups (sham group, model group, Guilu Taohong Formula group and L-carnitine group). After the establishment of models, the rats were treated with intragastric administration for eight consecutive weeks. The general condition of the rats was observed. After the gavage, the testicular and epididymal indices were calculated. Semen quality was assessed using an automatic semen analyzer. Apoptosis of testicular cells was assessed by TUNEL staining. And the expression levels of B-cell lymphocytoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteine aspartate protease-3 (caspase-3) in testicular tissue were detected by Western blot.
Results: Compared with the sham group, testicular index, epididymal index, sperm concentration, the percentage of progressive motility of sperm (PR%) and the expression level of Bcl-2 decreased in model group(P<0.01). An increased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were observed in model group as well(P<0.01). Compared with the model group, the testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 in Guilu Taohong Formula group increased significantly (P<0.05, P<0.01). A decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were detected in Guilu Taohong Formula group as well(P<0.01). Similarly, the L-carnitine group showed increased testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 protein (P<0.05, P<0.01), where showed decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins compared with model group (P<0.01, P<0.05).
Conclusion: Guilu Taohong Formula improves semen quality in VC model rats and reduces the apoptosis rate of spermatogenic cells in testicular tissue, which may be related to the promotion of Bcl-2 protein expression and the inhibition of Bax and caspase-3 protein expression levels.

National journal of andrology was founded in June 1995. It is a core journal of andrology and reproductive medicine, published monthly, and is publicly distributed at home and abroad. The main columns include expert talks, monographs (basic research, clinical research, evidence-based medicine, traditional Chinese medicine), reviews, clinical experience exchanges, case reports, etc. Priority is given to various fund-funded projects, especially the 12th Five-Year National Support Plan and the National Natural Science Foundation funded projects. This journal is included in about 20 domestic databases, including the National Science and Technology Paper Statistical Source Journal (China Science and Technology Core Journal), the Source Journal of the China Science Citation Database, the Statistical Source Journal of the China Academic Journal Comprehensive Evaluation Database (CAJCED), the Full-text Collection Journal of the China Journal Full-text Database (CJFD), the Overview of the Chinese Core Journals (2017 Edition), and the Source Journal of the Top Academic Papers of China's Fine Science and Technology Journals (F5000). It has been included in the full text of the American Chemical Abstracts, the American MEDLINE, the American EBSCO, and the database.
