Males typically have more skeletal muscle mass than females. Androgens promote the enlargement of skeletal muscle cells in a coordinated manner by acting on several cell types in skeletal muscle tissue. [12] One cell type, called the myoblast, conveys androgen receptors for generating muscle.
The anterior pituitary complex and hypophyseal portal system, where FSH and LH are released. Theca cells are responsible for synthesizing androgens, providing signal transduction between granulosa cells and oocytes during development by the establishment of a vascular system, providing nutrients, and providing structure and support to the follicle as it matures.
In female: stimulates maturation of Graafian follicles in ovary. In male: spermatogenesis, enhances production of androgen-binding protein by the Sertoli cells of the testes. 27 Galanin: GAL Peptide: central nervous system and gastrointestinal tract: GALR1, GALR2, and GALR3: modulation and inhibition of action potentials in neurons: 28
Research shows that older men and women with low testosterone have lower red blood cell counts and an increased risk of developing anemia. Anemia can produce symptoms like fatigue, weakness, loss ...
In general, androgens are considered "male sex hormones", since they have masculinizing effects, while estrogens and progestogens are considered "female sex hormones" although all types are present in each sex at different levels. [6] Sex hormones include: Progestogens. Pregnenolone → Progesterone → Allopregnanedione → Allopregnanolone
In both males and females, the sex organs consist of two structures: the internal genitalia and the external genitalia. In males, the gonads are the testicles and in females, they are the ovaries. These are the organs that produce gametes (egg and sperm), the reproductive cells that will eventually meet to form the fertilized egg .
Your muscle cells have receptors called androgen receptors. When testosterone binds to the receptors, it helps your muscles grow. But when T levels flag, the muscle can start to degrade.
Each type of cell behaves differently in response to FSH. Theca interna cells express receptors for luteinizing hormone . LH induces the production of androgens by the theca cells, most notably androstendione, which are aromatized by granulosa cells to produce estrogens, primarily estradiol. Consequently, estrogen levels begin to rise.
