May 2025 in “Veterinary Medicine and Science” In this study, oral melatonin given to male Pomeranian dogs with Alopecia X improved semen quality and testicular blood flow in a dose-dependent manner, but altered hormonal balance, indicating complex effects that require further investigation for long-term implications.
February 2018 in “Zenodo (CERN European Organization for Nuclear Research)” This study observed that administering 1000 mg/kg of LSFP significantly reduced serum FSH and LH levels and testicular index in male Wistar rats, while lower doses showed no such effect.
February 2018 in “The Journal of Sexual Medicine” In this animal study, finasteride exposure led to impaired spermatogenesis in rats, while the novel compound DA-9401, derived from three medicinal herbs, demonstrated potential in improving sperm parameters and reducing testicular apoptosis when used alone or with finasteride.
