Urinary hormones analysis

Within each intercourse (man or woman) there is no significant difference between testosterone (p > 0.05) or estrone (p > 0.05) levels amongst the February (reproduction season) and July (non-breeding period) examples. Therefore, the testosterone and estrone levels for February and July were averaged to calculate a testosterone that is single estrone concentration for every single animal. Suggest testosterone concentration had been 2.22 ± 0.38 ng/ml for male DGFs and 0.92 ± 0.11 ng/ml for feminine DGFs (Fig. 4 , panel panela). a ). Testosterone levels ranged from 0.30 to 9.16 ng/ml in men and 0.26 to 1.60 ng/ml in females (Fig. 4 , panel panelb). b ). Suggest testosterone concentrations had been notably greater (p 4 , panel panelc), c ), with females showing notably greater (p 4 , panel paneld). d ). Even though mean testosterone and estrone levels had been considerably various amongst the sexes, there was clearly some overlap into the hormones levels of men and women (Fig. 4 , panels panelsb b and andd), d ), especially for testosterone. The entire mean testosterone concentration for both sexes ended up being 1.69 ng/ml. Whenever this value ended up being used to anticipate intercourse, 100 per cent of females had been properly predicted, but just 44 % of males. For estrone, the entire mean concentration for both sexes had been 0.66 ng/ml. Making use of this value as being a boundary to anticipate intercourse, men had been properly identified 100 percent regarding the right time, but females had been only precisely identified 59 percent of that time period.
