What would a feedback loop for someone who has secondary hypogonadism and is receiving testosterone replacement therapy look like and why?

Which hormone promotes sperm production and secondary sex traits in males? A) Progesterone B) Calcitonin C) Testosterone D) Epinephrine

As males and females age they produce lower volumes of sex hormones. For women, taking testosterone to increase libido in becoming more common. Why is the same not common for males?

What is the primary role of FSH in males?     Develop and maintain secondary sex characteristics   Initiate sperm production in the testes   Stimulate the interstitial cells to produce testosterone   Stimulate the nurse cells to produce inhibin   Influence sexual behaviors and sex drive

What is lactational amenorrhoea?

A reproductive hormone that is secreted directly from the anterior pituitary is  follicle-stimulating hormone. progesterone. testosterone. estradiol. gonadotropin-releasing hormone.

Scientists have noticed a disturbing trend in the freshwater ecosystems in North America: a large number of male fish are found to contain female egg cells growing inside their testes. The feminization of male fish is called intersex, and its exact cause is still baffling many scientists. Many studies have shown that intersex can be induced when male fish are exposed to endocrine disruptors. An endocrine disruptor stimulates or inhibits the endocrine system, causing either an increase or decrease in hormone production. However, it is easier to demonstrate the direct cause and effect in a laboratory environment where the fish are only exposed to a single endocrine disruptor. In nature, there are many other variables such as low oxygen levels or warmer water temperatures that could also cause feminization in fish. Identify two reasons why we should be concerned about the feminization of fish.

Where does progesterone come from and what maintains the production of progesterone?

Name two endocrine disruptors, identify their source and explain how they can get into freshwater bodies? An example has been given.  Endocrine Disruptor: DDT…

Which of the following hormones controls the release of pituitary sex hormones? LH - luteinizing hormone FSH - follicle stimulating hormone GNRH - gonadotropin releasing hormone Testosterone
