This test measures the level of follicle-stimulating hormone (FSH) in a sample of your blood. A hormone is a chemical messenger in your bloodstream that controls the actions of certain cells or organs. FSH plays an important role in sexual development in children and fertility in adults.

Indicadores
A heterodimeric glycoprotein hormone secreted by the gonadotropic cells of the anterior pituitary gland. This hormone is involved in gonadal development, growth, maturation and reproductive processes, including the regulation of spermatogenesis in males and follicular growth and ovulation in females.
Indicadores
The most potent androgen, required for sex development. Dihydrotestosterone is synthesized from testosterone in the prostate gland, testes, hair follicles and adrenal glands by 5-alpha reductase. Dihydrotestosterone exerts its action similar to testosterone, which binds to and activates specific nuclear androgen receptors. After translocation into the nucleus, the activated hormone-receptor complex binds to the androgen response elements on the DNA and activates gene expressions that are required for sex development. Dihydrotestosterone is responsible for the formation of male primary sex characteristics and most male secondary sex characteristics during puberty, such as muscular growth, facial and body hair growth, and deepening of the voice.
Indicadores
Inhibin B, consisting of an alpha subunit and a beta B subunit linked by disulphide bonds, is a heterodimer hormone produced by the follicle cells of the ovary and by the Sertoli and Ledig cells of testis. Although other forms of inhibin also exist in men, inhibin B is the predominant form in the circulation in men.
