The aim of this study is to evaluate the effect of fasting versus non-fasting state on the total testosterone levels in women during the reproductive period.MethodsThis study was conducted at Faiha Specialized Diabetes, Endocrine and Metabolism Centerin Basrah, (Southern Iraq) betwe...
A temporary drought caused relatively high levels of early brood reduction for this population; 2- and 3-day-old chicks were most likely to starve. We found that chicks from testosterone-treated eggs were less likely to starve than control chicks, and were heavier on the days when most brood...
Testosterone is secreted at adult levels during three epochs of male life: transiently during the first trimester of intrauterine life (coinciding with masculine genital tract differentiation), during early neonatal life as the perinatal androgen surge (with still undefined physiologic significance), and ...
Using the barn swallow, Hirundo rustica, a migratory species, we found that plasma testosterone levels increased with increasing the proportion of eumelanin pigments compared with pheomelanin pigments, but not with the amount of pheomelanin pigments, during the mating period. In the Pacific swallow ...
striving to get results that just wouldn't come. After a few months at the gym I started to get really down, and began feeling as though I would never make any progress. I was still just as skinny as I had always been. During that time period I had tried numerous workout supplements...
Testosterone levels are high in young men, but plummet during aging. Low testosterone is associated with excess abdominal fat, loss of insulin sensitivity, and atherosclerosis.
randomized, double-blind, placebo-controlled study to assess the effects of testosterone supplementation on functional mobility, cognition, bone mineral density, body composition, lipids, quality of life, and safety parameters in older men with low normal testosterone levels during a period of 6 ...
Estrogen levels rise and fall throughout your life. During puberty, estrogen shoots up to help your body make physical changes, such as breast development. Levels change during your menstrual cycle: rising during ovulation, when your body produces an egg, and dropping during your period. It also...
We longitudinally monitored captive red-legged partridges (Alectoris rufa) and exposed males to high exogenous testosterone levels, anti-androgens, or a control treatment during each breeding period throughout their lives. Theory predicts that individuals maintaining high androgen levels should obtain ...
