Serum and seminal plasma hormonal profiles of infertile Nigerian male.

Male infertility constitutes a worldwide problem, especially in Nigeria where most men do not readily accept that they may contribute to the couple's infertility. In order to assess hormonal disturbances in the male infertility we compared male reproductive hormonal levels in human serum and seminal plasma and evaluated the hypothalamic-pituitary-testicular-axis in infertile Nigerian males. The biophysical semen parameters were assessed by W.

Selenium status of idiopathic infertile Nigerian males.

Selenium concentration in the sera and seminal plasma of 60 infertile males (40 oligospermia and 20 azoospermia) and 40 males with proven evidence of fertility (normospermia; control group) were estimated using atomic absorption spectrophotometry. Results were correlated with spermatogram and hormonal levels in order to determine their relationship and significance in male infertility. The mean serum concentrations of selenium was found to be significantly increased in oligospermic compared to azoospermic subjects and controls (p < 0.

Seminal plasma zinc level in users of gossypol.

Seminal plasma zinc levels were determined in 13 healthy male volunteers on gossypol, a triterpenoid aldehyde extracted to purity from cotton plant which has been found to be an orally active male fertility regulation agent that is simple, economical and reversible. Each subject was given 20 mg gossypol tablet daily until azoospermia occurred. Thereafter, a maintenance dose of 7.

Hyperprolactinaemia as a cause of male infertility in Ibadan.

Sera from normospermic, oligospermic and azoospermic adult Nigerians were analysed by radioimmunoassay (RIA) for prolactin (PRL) and testosterone (T). The mean +/- SEM DRL concentration (M.I.

The prevalence of insulin resistance and other cardiovascular disease risk factors in healthy elderly southwestern Nigerians.

We assessed the prevalence of coronary heart disease (CHD) risk factors including insulin resistance in 500 (205 males, 295 females) healthy elderly (age > 55 years) indigenous, low socioeconomic group Yorubas residents in either an urban slum (n = 240) or a rural town (n = 260) in southwestern Nigeria. Anthropometric indices, blood pressure and fasting plasma levels of glucose, lipids, insulin and insulin resistance were measured. The results indicated that: (i) gross obesity (4.
