چکیده
Abstract Introduction Variation in testosterone levels by season and month have been reported, however results inconsistent across studies. Large series are conflicting with reported peaks June, October, December, January. Testosterone most of these studies nadir the spring. The etiology for variability remains unknown but is likely multifactorial including sunlight exposure, sleep duration, outdoor temperature. Objective To determine if there seasonal a large cohort men this may be clinically relevant. Methods Using single institutional database, were obtained ages 18-99 from 2010-2021 who had at least 2 drawn within 2-year period. Patients currently or previously on exogenous testosterone, stimulating medications, suppressing aromatase inhibitors excluded study. Climate data mean monthly temperature Miami-Dade County, FL was PRISM Group. Minutes daylight fifteenth day each applied as representative duration month. Results There 3,377 total patients included study, 9495 measured all having more levels. age 58.8 years old. In winter level 422 ng/dl (Figure 1.), average time 682 minutes, 68 F. spring 412 ng/dl, 801 78.4 summer 416 780 83.6 fall 417ng/dl, 661 75.3 Conclusions Our findings suggest highest winter, lowest steady increase fall.

Seasonal variation in seminal characteristics, testicular measurements and plasma testosterone concentration in Iranian Khalkhali bucks
The aim of the present study was to determine seasonal variations in semen characteristics, testicular size, and plasma testosterone concentration in Iranian Khalkhali goats. An artificial vagina was used to collect semen from 10 bucks (2–4 years of age), from November 2013 to October 2014. Testicular circumference was higher (P<0.05) from September to October. Ejaculate volume, sperm ...
متن کاملSeasonal variation in serum testosterone, testicular volume, and semen characteristics in the coyote (Canis latrans).
The coyote is a seasonally breeding mammal, with most copulations occurring between December and April (depending on location). The objective of this study was to characterize seasonal changes in serum testosterone concentrations, testicular volume, and ejaculate quantity and quality in captive male coyotes. There were seasonal differences in testicular volume, with the greatest volume (20.2+/-...
متن کاملSeasonal and population variation in male testosterone levels in breeding orange-crowned warblers (Vermivora celata).
Comparative hormone studies can reveal how physiology underlies life history variation. Here, we examined seasonal variation in plasma testosterone concentration between populations of male orange-crowned warblers (Vermivora celata) breeding in Fairbanks, Alaska (V. c. celata) and on Santa Catalina Island, California (V. c. sordida). These populations face different ecological constraints and e...
متن کاملSeasonal variation in male testosterone levels in a tropical bird with yearround territoriality
Testosterone is important in mediating investment in competing activities such as territoriality, parental care, and maintenance behavior. Most studies of testosterone function have focused on temperate species and less is known about the role of testosterone in territoriality or variation in mating systems of tropical species. Results of studies of tropical species with year-round territoriali...
