Abstract:
The potential health hazard of the large amounts of Lead that occurs in canned baby food, domestic water from lead-lined tanks and, in printing and petroleum industries. Lead acetate administration at a does of 8 mg/kg body weight for 21 days resulted a significant increase in adrenal steroidogenic enzyme (Delta5-3beta- HSD) and serum levels of corticosterone, while serum levels of testosterone, FSH, LH and testicular spermatogenesis were decreased in albino rats. But lead-treated rats received exogenous testosterone for the last 14 days of lead treatment, showed prevention of adrenocortical hyperactivity by decreasing adrenal Delta5-3beta-HSD activity and serum level of corticosterone. Testosterone administration also increased serum level of testosterone, FSH and LH along with spermatogenesis. The results suggest that testosterone supplementation in lead-treated rats protects adrenocortical activity and testicular spermatogenesis.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...
Testosterone: Functions and Regulation
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
Spermatogenesis
Anatomy of the Adrenal Glands
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct regions...
