Summary Introduction
To determine:
The reason for gynomastia (breast development in males) due to chronic marijuana effects.
Introduction:
An endocrine gland can be defined as a gland that releases hormones directly into the bloodstream. The endocrine organs that are involved in the production of sex differences are the reproductive organs ovaries and testes. Testes help in the production of male gametes, or sperm and testosterone. This hormone helps in the development of male sexual characters.

- Sexual arousal results in a generally positive sympathetic response, e.g. increased heart rate, increased breathing rate and depth, etc. How is it, then, that erection can occur if sympathetic activity causes vasoconstriction and prevents blood flow into the vascular spaces of the penis?arrow_forwardIdentify one aspect of testosterone that could be useful in treating individuals with HIV.arrow_forwardSex hormone secretion is governed by a negative feedback loop to the hypothalamus and pituitary, similar to that for thyroid hormone or cortisol. Because of this, a veterinarian can use a blood test to find out whether a female dog has been neutered. Dogs who still have their ovaries have a lower blood level of luteinizing hormone (LH) than dogs who have been neutered. Explain why removing a dog’s ovaries would result in an elevated level of LH.arrow_forward
- List three different menopausal symptoms that can be counteracted by HRT (hormone replacement therapy). What is the reason why both estrogen and progestin are often included in these preparations?arrow_forwardHormone replacement therapy was advertised first to women in the 1990s as a way of increasing their youthfulness. Hormone replacement therapy today is usually taking pills to increase someone's estrogen or testosterone supply. Pick either estrogen or testosterone. For either one: 1) How does your chosen sex hormone work at the cellular and at the molecular level? 2) How do these hormones improve the reproductive system as a whole? 3) What are the benefits of doing hormone replacement therapy? 4) What are the harms of doing hormone replacement therapy? 5) Who would be an ideal candidate for hormone replacement therapy?arrow_forwardWhich of the following is/are true with regards to hormones in the reproductive tract? Estrogen secretion is stimulated exclusively by LH. Progesterone is secreted by ovarian follicles & the corpus luteum. Progesterone secretion is stimulated exclusively by FSH. Estrogen is secreted by ovarian follicles & the corpus luteum. All of the abovearrow_forward

Usual symptoms of teratoma are diabetes insipidus, neurological issues, and a reduction in pituitary hormones.Which of the following correctly describes the symptoms of a 10-year-old girl with a teratoma tumour in the pituitary gland? Select one: a. Increased levels of ADH and stimulation of the development of secondary sexual characteristics b. Decreased levels of ADH and inhibition of the development of secondary sexual characteristics c. Decreased levels of FSH and stimulation of the development of secondary sexual characteristics d.

- There is considerable advertising directed at men in their 50s and older suggesting that they can reverse the effects of aging by taking supplemental testosterone ( "maybe you have low T!") . Surprisingly, their doctors often comply with requests for supplemental testosterone with little or no testing to find out if their levels are actually abnormal. It turns out abnormally low testosterone levels are fairly rare in men, so not surprisingly, most men derive little benefit from the supplements. Often these patients, when they don't get the desired results, being guys, think increasing their dosage by 3 or 4 times would be better. What would be the effects of increasing the testosterone dosage on the following hormone levels? A. Low FSH; high GnRH, LH and estradiol B. Low LH, FSH and estradiol; high GnRH C. Low GnRH, FSH, and LH; high estradiol D. Low GnRH and LH; high FSH and estradiol E.
