research Evaluation of the effect of injection of dutasteride as mesotherapeutic tool in treatment of androgenetic alopecia in males
Dutasteride mesotherapy helps treat male hair loss but may harm sperm and sexual function.
research Applications of Marine Organism-Derived Polydeoxyribonucleotide: Its Potential in Biomedical Engineering
PDRN, derived from salmon sperm, shows promise in healing wounds, reducing inflammation, and regenerating tissues, but more research is needed to understand its mechanisms and improve its use.
research Androgen levels and apoptosis in the testis during postnatal development of finasteride-treated male rat offspring
Finasteride treatment in male rats can reduce fertility and affect sperm development in their offspring.
research COVID-19 Infection Induce miR-371a-3p Upregulation Resulting in Influence on Male Fertility
