Testosterone levels and stress in women
This study evaluated the relation between testosterone changes in response to anticipatory stress and several psychological variables that contribute to the stress reaction. Salivary testosterone was determined in 76 female students under stress-free conditions and before an important examination. Individual stress reactions were highly variable in direction and extent: both significant increases and decreases were found. Thus the data did not co…

The distribution of plasminogen (PLG) polymorphism in the Namibian !Kung San and Kavango populations
Genetic polymorphism of the PLG serum protein was examined in the Namibian !Kung San and Kavango (Bantu) populations by means of IEF technique. The two samples revealed very similar allele frequencies (!Kung San: PLG*A = 0.8351, PLG*B = 0.1649; Kavango: PLG*A = 0.8228, PLG*B = 0.1732 and PLG*M4 = 0.004). The Namibian distributions were within previously observed African PLG ranges. The effects of natural selection were also discussed.
HP and GC subtype distribution in the !Kung San and Kavango in Namibia
The distribution of the HP and GC serum protein polymorphisms in the !Kung San and Kavango (Bantu) populations in Namibia were examined. The obtained allele frequencies of GC marker system were very similar in both populations (GC*1F approximately equal to 0.80, GC*2 approximately equal to 0.10), while the distributions of the HP subtypes in the !Kung San sample (HP*1F = 0.0967, HP*1S = -.1452, HP*2FS = 0.7581) differed markedly from those in the…

Sex hormone levels and body hair growth in !Kung San and Kavango men from Namibia
The relation between hair growth and levels of sex hormones in serum and saliva was investigated in 256 !Kung San and Kavango men (ages 18 to 39 years) from Namibia/Southern Africa. Serum concentrations of total testosterone (Tser), 5α‐dihydrotestosterone (DHT), and estradiol (E2) as well as the level of bioavailable non‐SHBG‐bound testosterone in the saliva (Tsal) were determined by radioimmunoassay. The distribution and density of scalp and fac…
Hormonal, anthropometrical, and behavioral correlates of physical aggression in !Kung San men of Namibia
Differences in physical aggression among 114 male !Kung San (bushmen) from Namibia were investigated with regard to sex hormone levels, body dimensions, consumption of alcohol, and degree of acculturation. Subjects were classified from injuries resulting from prior conflicts with mutual physical aggression between the opponents as either violent or nonviolent. The comparison of mean sex hormone values (total serum testosterone, Tser; serum 5α-dih…
Relations between sex hormone level and characters of hair and skin in healthy young men
Total testosterone and dihydrotestosterone in blood serum as well as free testosterone in saliva were determined by radioimmunoassay in 110 healthy young men. The results were compared with the development of terminal hair on the trunk and limbs, with the disposition to balding and with the disposition to acne. No significant correlations were found between terminal hair development and absolute androgen levels; however, some significant values w…
Anthropometric-hormonal correlation patterns in San and Kavango males from Namibia
Correlations between sex hormone levels and body dimensions--so far investigated only in Caucasian populations--were analysed using data from 114 !Kung San hunter-gatherers and 137 urban and rural Kavango men from Namibia. The androgens testosterone (Tser) and 5 alpha-dihydrotestosterone (DHT) in the serum and free testosterone in the saliva (Tsal) as well as oestradiol (E2) in the serum were determined by the radioimmunoassay method. The body di…
Serum and saliva sex hormone levels in !Kung San men
Serum concentrations of testosterone (Tser), 5αL‐dihydrotestosterone (DHT), estradiol 17β (E2), and free testosterone in saliva (Tsal) were determined by means of the radioimmunoassay method in 114 !Kung San men living in the Bushmanland district of Namibia. The healthy men (mean age 26.4 years) were asked about their dietary habits over the last two months and their acute alcohol intake during the 24 hours preceding the blood and saliva sampling…
Sexual hormone level and body shape of the !Kung San. A contribution to the paedomorphism Sanid populations
In order to test the hypothesis that oestrogens as well as androgens modify the body shape resp. the paedomorphous habitus of !Kung San circulating levels of sex hormones (testosterone, 5 alpha-dihydrotestosterone, and oestradiol in the serum as well as free testosterone in the saliva) of 114 healthy !Kung San men from the Northern Kalahari of Namibia were quantitatively determined by means of the radioimmunoassay method. The probands were descri…
Comparisons of the intra-and inter-individual variability in sex hormone levels of men
Six blood samples were taken from each of 33 healthy young men during the course of 2 weeks. From these, the testosterone, dihydrotestosterone, and oestradiol levels were determined. In addition, free testosterone was measured using saliva samples obtained from 23 of the subjects. Both coefficients of variation and variance analyses showed that the inter-individual variability is greater than the intra-individual for all of the hormones. No influ…
