List the two principal functions of the testis?
sperm production and testosterone production
Describe the phases of spermatogenesis and hormonal controls?
Spermatogenesis is the process of sperm production in males that occurs in the seminiferous tubules of the testes. It is divided into three phases: proliferation, meiosis, and spermiogenesis. The process is regulated by hormones including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone. FSH stimulates the production of sperm, LH triggers testosterone production, and testosterone is essential for spermatogenesis to occur.
What hormone suppresses spermatogenesis with out affecting testosterone secretion?
Inhibin is a hormone that specifically suppresses spermatogenesis without affecting testosterone secretion. It is produced by the Sertoli cells in the testes and acts to inhibit the secretion of follicle-stimulating hormone (FSH) from the pituitary gland, which is necessary for sperm production. This helps to regulate the balance of hormones involved in male reproductive function.
Do the ovaries release estrogen and progesterone in response to gonadotropic hormones from the pituitary gland?
Yes, the ovaries release estrogen and progesterone in response to gonadotropic hormones (FSH and LH) from the pituitary gland. FSH stimulates the development of follicles in the ovaries, leading to estrogen production, while LH triggers ovulation and promotes the production of progesterone from the corpus luteum.
What causes the changes of puberty?
The main cause of change at puberty are started by the production of our hormones(testosterone for boys and the estrogen and progesterone for girls)
Two hormones necessary for sperm production?
Testosterone and Follicle Stimulating Hormone from the Pituitary gland.
What Control of sperm production is the function of which hormones?
Sperm production is controlled by hormones such as follicle-stimulating hormone (FSH) and luteinizing hormone (LH) released by the pituitary gland in response to signals from the hypothalamus. FSH stimulates sperm production in the testes, while LH regulates testosterone production by the interstitial cells in the testes, which is essential for sperm maturation.
What is the hormones secreted by the teste?
Testosterone
What Gonadotropic hormones are secreted by the anterior pituitary?
Adrenocorticotropic Hormone (ACTH): Secretion of glucocorticoids Thyroid Stimulating Hormone (TSH):Secrete thyroid hormones (Controls metabolism) Follicle Stimulating Hormone (FSH): Growth of reproductive system Luteinizing Hormone (LH): Sex hormone production Growth Hormone (GH): Promotes growth Prolactin: Secretes estrogen/progesterone and stimulates mammary glands to push milk into ducts
What hormones target the gonads?
There are a few hormones that act on the gonads and they are different for both the male and female reproductive systems.In females, the gonads are the ovaries. The hormones include:Estrogen - This promotes the production of secondary sex characteristics and sex drive.Progesterone - This hormone helps prepare the uterus for pregnancy.Inhibin - This hormone inhibits the secretion of follicle stimulating hormone.In males, the gonads are the testes. Their corresponding hormones include:Testosterone - This stimulates spermatogenesis, growth, and maturation of sperm as well as the production of secondary sex characteristics.Inhibin - This hormone inhibits the secretion of follicle stimulating hormone.
Does the overproduction of the growth hormone causes premature ossification of the epiphyseal disc?
No the overproduction of growth hormones can cause pituitary gigantism. The over production of Sex hormones( estrogen /testosterone) can cause premature ossification;estrogen more so than testosterone.
What are two functions of the testes?
One of the functions of the testes is to produce sperm. The other function of the testes is to produce hormones, namely testosterone.
