What hormone feeds back to the hypothalamus so that only one follicle will reach maturity?
Step by step
Solved in 3 steps
- In the anterior pituitary region, do you see multiple cell types in each follicle or does each follicle contain a single cell type? How can you tell each cell type apart from one another? Hint: think about the names and staining.Which male sex hormone that helps maintain sexual organs ?What is Follicle stimulating hormone (FSH) ?
- Where does progesterone come from and what maintains the production of progesterone?Name three anterior lobe hormones that have reproductive functions and three that have nonreproductive roles.What target organs are stimulated by each of thesehormones?Which hormone is controlled by both a releasing and an inhibiting hormone from the hypothalamus? prolactin (PRL) follicle stimulating hormone (FSH) oxytocin
- What is the relationship between luteinizing hormone (LH), follicle stimulating hormone (FSH) and estrogen.Are estrogen and progesterone antagonistic hormones? Why or why not?A 38-year-old male is upset about his low sperm count and visits a "practitioner" who commonly advertises his miracle cures of sterility. The practitioner is a quack who treats conditions of low sperm count with megadoses of testosterone. Although his patients experience a huge surge in libido, their sperm count is even lower after hormone treatment. a) Which two glands would be responsive to the megadose of testosterone? b) Identify the two hormones that would be affected by the megadose of testosterone. Would their levels increase or decrease? c) What role, if any, would either of the affected hormones have on the man's reduced sperm count?
