Boys also have a physiological cycle, and the male physiological cycle is related to the secretion of gonadotropin-releasing hormone by the hypothalamus, gonadotropin by the pituitary gland, and testosterone by the testes.
The hypothalamus, pituitary gland and testes, together, form the axis of male sex hormone secretion. The hypothalamus secretes gonadotropin-releasing hormone into the pituitary portal system to act on the pituitary gland, and the secretion of gonadotropin-releasing hormone is regulated by seasonal, diurnal and other factors, and is generally secreted more in the spring and early morning, and there is a pulsatile secretion once every 90 to 120 minutes.
After the pituitary gland secretes luteinizing hormone and follicle-stimulating hormone to act on the testes, the testes are stimulated by luteinizing hormone to secrete testosterone, and under the stimulation of follicle-stimulating hormone, the spermatogonial cells develop into spermatozoa in the seminiferous tubules, and testosterone is maintained at a level of 9.45~37.45nmol/L under the action of luteinizing hormone.
The level of testosterone in men is regulated by hormones such as gonadotropin-releasing hormone and luteinizing hormone, and is also affected by factors such as living habits, mental state and obesity. If you want to have a male sex hormone test, please follow your doctor’s instructions.
