Gonadotropin-releasing hormone (GnRH) causes the release of what hormone: A. Leuteinizing hormone (LH) B. Thyroid-stimulating hormone (TSH) C. Somatostain D. Growth hormone (GH) A rise in ___ causes the hypothalamus to be stimulated by estrogen. A. Estrogen. B. ACTH. C. Progesterone...
Give one example of the hormonal stimulus for the release of hormones. Briefly explain the role of Testosterone in the male reproductive system. Which hormone triggers ovulation? In men, the hormone ___ initiates sperm production in the testes and ___ stimulates secretion of testosterone...
The hormone FSH—follicle stimulating hormone—is produced and released by the pituitary gland. It's this hormone that triggers the follicles to mature. As the follicles increase in size, they release more estrogen. Higher levels of estrogen signal the pituitary gland to slow down the production...
Several medications are used in assisted reproductive technology to suppress the release of LH, which can prematurely release follicles before an egg retrieval in in vitro fertilization. These medications, which include: Leuprolide acetate Ganirelix Cetrotide are called Gonadotropin Releasing Hormone (GnRH)...
Luteinizing hormone (LH), the other reproductive pituitary hormone, aids in egg maturation and provides the hormonal trigger to cause ovulation and the release of eggs from the ovary. How are sperm cells produced? Most men have two testes. The testes are responsible for making testosterone, the...
Nugenix® GH-Boost is designed to be taken before bed, so while you’re resting it’s putting in work to support endocrine balance, promote better sleep quality, and trigger the all-powerful human growth hormone.They also make several other supplements like Testosterone boosters. You’re ...
Signal pheromones are a type of pheromone that is used to Short-term effects, such as the release of neurotransmitters that activate a reaction, are caused by signal pheromones. For example, the chemical Gonadotropic releasing hormone (GnRH) acts as a neurotransmitter in rats to cause lordosis be...
Some agonists are very broad in the range of movements they may trigger, while others are more focused. The physician’s decision of which chemical or drug to utilize during the course of treatment often depends on the type of movement desired and the muscle groups involved in the process of...
The HPG axis is essentially your body’s control center for testosterone production. It involves a feedback loop between the hypothalamus in the brain, the pituitary gland (also in the brain), and the testicles.When testosterone levels are low, the brain tries to compensate by increasing GnRH,...
Once the egg is released, LH continues to impact the cellular structure of the former follicle. Before ovulation, granulosa and theca cells in the follicle produce estrogen. After ovulation, LH triggers these cells to transform into the corpus luteum and they begin to release the hormone progeste...
