Types of Hormones02:13

Types of Hormones

83.8K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

Types of Hormones

7.2K
Hormones are classified into four main groups: steroids, eicosanoids, amino acid-based derivatives, and peptide hormones.
Steroids and eicosanoids fall under the category of lipid-soluble hormones. Steroids are derived from cholesterol and feature four interconnected carbon rings with variable side chains. Notable examples include estradiol from ovaries and testosterone from testes, exemplifying the critical roles of these lipid-soluble hormones in reproductive physiology. Eicosanoids, derived...

Hormonal Regulation01:33

Hormonal Regulation

36.1K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Plant Hormones01:56

Plant Hormones

27.7K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Infertility in Males01:23

Infertility in Males

575
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...

Area of Science:

  • Reproductive endocrinology and male contraception.

Background:

  • Male hormonal contraceptives aim to suppress spermatogenesis by inhibiting pituitary gonadotrophins and depleting intratesticular testosterone.
  • Previous trials utilized testosterone alone, with newer research exploring combination therapies for enhanced efficacy.

Purpose of the Study:

  • To evaluate the efficacy of combined hormonal regimens for male contraception.
  • To identify promising combination therapies for future clinical application.

Main Methods:

  • Testing synergistic combination regimes using newer androgens and other agents.
  • Focusing on the combination of long-acting testosterone preparations with progestogens.

Main Results:

  • The combination of long-acting testosterone and progestogen shows significant promise.
  • This synergistic approach is more effective than testosterone alone.

Conclusions:

  • Combined hormonal contraception, specifically testosterone and progestogen, is a highly promising strategy for male birth control.
  • This approach is expected to lead to an accepted male contraceptive product in the near future.
