Fraternal birth order (FBO) appears as a prenatal cause of 15% of homosexual males (gays) through mnemonic maternal anti-male factors. Non-right-handed men seem to be protected from homosexuality. Four hypotheses are proposed: (1) androgenic factors of non-right-handedness neutralize anti-male factors; (2) non-right-handedness and homosexuality are lethal or produce mental impairment; (3) non-r...

Haploid microspore-derived embryos (MDEs) of wheat were obtained by in vitro androgenesis. These  embryos were employed to evaluate the transient expression of GUS gene (uidA) following particle bombardment. Using the Bio-Rad PDS-1000/He system, the physical parameters including rupture disk pressure (900, 1100 and 1350 psi); microprojectile travel distance (6 and 9 cm); gold particles size (0....

Changes in concentrations of 17beta-estradiol (E2) and androgenic hormones were measured in turkey embryos incubated in long-term, shell-less culture (ex ovo) and in ovo. Blood samples were obtained from both sets of embryos on Days 14, 16, 18, 20, and 22 and from embryos incubated in ovo on Days 24, 26, and 28. Ex ovo and in ovo embryos showed no differences in either hormone within sexes, wit...

physiological mediators of human host such as androgenic hormones interfere pathogenic fungal growth. it has been revealed that the growth of yeasts as well as of dermatophytes is influenced by human androgenic hormones in vitro. in this reason for in vivo condition, the andrgenic hormones level must be measured in patients with dermatophytosis and healthy individuals. to this purpose we measur...

This pioneering work reports successful androgenic plant development via embryogenesis from microspore calluses in anther cultures and estimation of bioactive metabolites vitro regenerants parent (control) Cambod tea, Camellia assamica ssp. lasiocalyx (Planch MS) cultivar TV19. Anthers bearing microspores at early-to-late uni-nucleate stage were selected to initiate androgenesis. A pre-treatmen...

OBJECTIVE The relationship between musculoskeletal injuries and anabolic-androgenic steroids is not well understood. The purpose of our study was to investigate the association between self-reported anabolic-androgenic steroids use and the prevalence of musculoskeletal injuries in a unique group of retired professional football players. DESIGN A general health questionnaire was completed by 2...

Embryogenesis in plants is a unique process in the sense that it can be initiated from a wide range of cells other than the zygote. Upon stress, microspores or young pollen grains can be switched from their normal pollen development towards an embryogenic pathway, a process called androgenesis. Androgenesis represents an important tool for research in plant genetics and breeding, since androgen...

We investigated the effect of long-term supraphysiologic doses of anabolic androgenic steroids (AAS) on atrial electromechanical delay (AEMD) in male bodybuilders. We clearly demonstrated that long-term consumption of supraphysiologic doses of AAS is associated with higher values of inter- and intra-AEMD in healthy young bodybuilders.
