The purpose of this meta-analysis is to study the impact varicocele repair in largest cohort infertile males with clinical by including all available studies, no language restrictions, comparing intra-person conventional semen parameters before and after varicoceles.
Both glial cell line-derived neurotrophic factor (GDNF) and fibroblast growth 2 (FGF2) are bona fide self-renewal factors for spermatogonial stem cells, whereas retinoic acid (RA) induces differentiation. In this study, we investigated the functional differences between FGF2 GDNF in germline niche by providing these using a drug delivery system vivo. Although both expanded GFRA1+ subset of undifferentiated spermatogonia, FGF2-expanded expressed RARG, which is indispensable proper...
Testosterone affects several organs in the body and is very important for male well-being. Aging men with late-onset hypogonadism (LOH) experience physiologic, psychiatric, sexual symptoms related to a decline serum concentration of testosterone age. However, it well-known that extent does not correlate severity LOH-related symptoms. Therefore, difficult diagnose treat patients LOH. In addition, symptoms, response replacement therapy (TRT), medical insurance coverage differ among ethnicities...
