Impotentia generandi (IG) is a major problem in male dromedary camels. The objective of this research was to characterize the FSH, LH and testosterone profiles and their association with clinical findings and semen characteristics in IG-male dromedaries.

Despite the heterogeneity of prostate cancer (PCa), androgen stimulation is fundamental to its development, growth and lethality. Therefore, the blockade of androgen receptor (AR) signaling is critical to controlling the disease, even after progression with castrate levels of androgens.

Background Ketoconazole (Keto), an antifungal drug and a common therapeutic option in the treatment of advanced prostate cancer, is known to cause reproductive dysfunctions. Like Keto, melatonin has antifungal and anticarcinogenic actions.

Kidney stone disease (KSD) is one of the earliest medical diseases known, but the mechanism of its formation and metabolic changes remain unclear. The formation of kidney stones is a extensive and complicated process, which is regulated by metabolic changes in various substances.

Spermatogenesis is a complex and elaborate differentiation process and is critical for male fertility. The hypothalamic-pituitary-gonadal axis serves as a significant neuroendocrine system to regulate spermatogenesis.

Females have less incidence/prevalence of kidney stone disease than males. Estrogen thus may serve as the protective factor but with unclear mechanism. This study explored cellular mechanism underlying such stone preventive mechanism of estrogen.

To investigate the relationship between the ratio of index to ring finger lengths (2D:4D ratio), reflecting androgen exposure in utero, and reproductive function among men.

Male patients (N = 180) who consulted for fertility issues participated in the study.
