Introduction
1. What organs are involved in hormonal control of male reproductive functions?
Testis, hypothalamus, an anterior pituitary.
Hormonal Control of Male Reproductive Functions
2. a. Describe gonadotropin releasing hormone (GnRH) production.
At puberty the hypothalamus secretes GnRH which stimulates anterior.
b. Describe GnRH affects on the male anterior pituitary.
GnRH goes to a GPCR and increases the levels of Ca2+ which causes stimulation of synthesis and secretion of FSH and LH.
3. What affect does luteinizing hormone (LH) have on the testes?
It stimulates Leydig cells to secrete the hormone testosterone.
4. a. What affect does testosterone and FSH have on the testes?
Sterol cells produce ABP which binds and maintains increased levels of testosterone.
b. What affect is the affect of androgen-binding protein?
ABP's production is regulated under influence of FSH on Sertoli cell, enhanced by insulin, retinol, and testosterone.

America Endangered species are plant and animal species that are in danger of extinction, the dying off of all individuals of a species. Over 19,000 plant species and 5000 animal species around the globe are classified as endangered, and many thousands more become extinct each year before biologists can identify them (Microsoft 1). The primary ca...
In order to assess the one must first take an overview of the whole of the whole disease. One must understand the disease and its enormity on a global basis. Malaria is a protozoan disease of which over 150 million cases are reported per annum. In tropical Africa alone more than 1 million children under the age of fourteen die each year from Malar...

The various kinds of dinosaurs are classified in two for...
Ever since the publication of Charles Darwin's The Origin of Species was published, there has been an ongoing debate between science and religion. Scientists have formulated many theories as to the origins of man and to the creation of the earth, whereas religious groups have one main creation theory, based on the "Genesis" story of The Bible. Thes...
Lamprey is a common name for about forty species of jawless, eel-like fishes. They are very smooth skinned and scaleless. Some can grow up to three feet in length, usually only in the oceans. All lampreys are dull colored, ranging from light-tan to molted-brown or bluish-black. Scientist consider the lamprey to be one of the least developed vert...
