The effects of exposure to chemical weapons containing sulfur mustards on the serum levels of total and free testosterone. gonadotropins and prolactin was investigated in young Iranian men. In the first five weeks after injury both serum total and free testosterone were significantly decreased as compared to control values. Three of 13 men had total testosterone below 300 ng/dL and two of ...

The TMPRSS2 protein is an entry pathway for SARS-CoV-2, its expression up-regulated by testosterone. Men have 7 to 8 times higher serum testosterone than women. We propose that patients hospitalized with COVID-19, levels of testosterone, worse outcomes those lower levels.

OBJECTIVE To determine correlation of serum total testosterone with body mass index (BMI) and waist hip ratio (WHR) in healthy adult males. METHODS A cross sectional study was conducted on 200 nonsmoker healthy males (aged 30-50 years) university employees. They were selected by convenience sampling technique after a detailed medical history and clinical examination including BMI and Waist Hi...

This study was aimed at determining the blood serum testosterone level and its relationship with scrotal circumference and physical characteristics of semen in Nili-Ravi buffalo bulls. Semen samples were collected weekly from three buffalo bulls of 14 years age for 12 weeks and were evaluated for physical characteristics i.e. ejaculatory volume, sperm motility, sperm concentration, pH and sperm...

BACKGROUND Level of the testosterone in a man's life span is very important. Studies on the serum testosterone concentrations in different age groups of healthy men were controversial. The aim of this study was to investigate dynamic changes of serum reproductive hormones with aging in healthy Chinese male and to compare its correlation with age. METHODS Total of 1,093 healthy Chinese men fro...

Background: Chemotherapy or irradiation is associated with impaired fertility. The aim of this study was to investigate the possible protective role of testosterone enanthate (TE) on the proliferative activity, plasma testosterone level and morphometry of epithelial cells of seminal vesicles in busulfan-induced spermiotoxicity. Materials and Methods: Sprague- Dawley rats were divided into 4 gro...

As men age, their serum testosterone concentrations decrease, as do their bone densities. Because bone density is also low in hypogonadal men, we hypothesized that increasing the serum testosterone concentrations of men over 65 yr to those found in young men would increase their bone densities. We randomized 108 men over 65 yr of age to wear either a testosterone patch or a placebo patch double...

Activity of alkaloid extract of caricapryl-99 seeds [Carica papaya Linn seeds] on the serum levels of steroid hormones was studied in adult male albino rats. Three tolerated doses obtained from the graph of percentage toxicity [10, 50 and 150 mg/kg] were separately administered orally, daily for three days to three groups of male rats [n=5] while group four of 5 rats received the vehicle [corn ...
