Summary
Testosterone, produced by Leydig cells, circulates freely to target cells. Anti-androgens block this uptake, impacting testosterone
Area of Science:
- Endocrinology
- Molecular Biology
Background:
- Testosterone synthesis primarily occurs in Leydig cells.
- Testosterone secretion exhibits episodic patterns and circadian variation.
- Only unbound testosterone in circulation is biologically active.
Purpose of the Study:
- To elucidate the mechanism of testosterone uptake by target cells.
- To understand the action of anti-androgens in relation to testosterone.
Main Methods:
- Review of existing literature on testosterone metabolism and action.
- Analysis of cellular uptake mechanisms for testosterone and its metabolites.
Main Results:
- Free testosterone enters target cells and binds to specific receptors.
- In some tissues, testosterone is converted to 5alpha-dihydrotestosterone before receptor binding.
- Anti-androgens primarily inhibit the uptake of testosterone or its metabolites.
Conclusions:
- Testosterone's biological activity depends on its free fraction and cellular uptake.
- The mechanism of action for anti-androgens involves blocking testosterone uptake pathways.

01:08Intracellular Hormone Receptors
Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell
01:31Hormones of the Adrenal Glands
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
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...

01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
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...

01:26Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
01:27Signs of Puberty
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
01:27Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
