- Testes. Singular, testis. The paired male gonads, they are the primary organs of the male reproductive system and measure about two inches in length and one inch in diameter. They are located in the scrotum, or scrotal sac. Their role is to produce sperm and the hormone testosterone.he paired male gonads, they are the primary organs of the male reproductive system and measure about two inches in length and one inch in diameter.

- Embryological and Fetal Events. Sex is determined by the sex chromosomes at conception; females have two X chromosomes and males have an X and a Y chromosome. Sexual Differentiation of the Reproductive System. The gonads of both males and females begin to develop during week 5 of gestation. During week 7 the gonads begin to become testes in males, and in week 8 they begin to form ovaries in females. The external genitalia arise from the same structures in both sexes, with differentiation occurring in week 8.

An Introduction to Male and Female Gonads Gonads. Gonads are the male and female primary reproductive organs. The male gonads are the testes and the female gonads are the ovaries. These reproductive system organs are necessary for sexual reproduction as they are responsible for the production of male and female gametes.s a component of the endocrine system, both male and female gonads produce sex hormones. Male and female sex hormones are steroid hormones and as such, can pass through the cell membrane of their target cells to influence gene expression within cells.

Male Gonad Hormones. 2  Androgens are hormones that primarily influence the development of the male reproductive system. 3  Although found in much higher levels in men, androgens are also produced in women. 4  Testosterone is the main androgen secreted by the testes.

- The sperm has to go through 5 different organs, 1st: Testes, 2nd: Epididymis, 3rd: Vas Deferens, 4th: Urthra, 5th: Penis. Testes: The Male Reproductive Organs that make sperm and testosterone. Epididymis (EP UH DID I MIS) : Tightly coiled tube where the sperm matures and is stored. Vas Deferens: A long tube.

- The entire male reproductive system is dependent on hormones, which are chemicals that stimulate or regulate the activity of cells or organs. The primary hormones involved in the functioning of the male reproductive system are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone.he external structures of the male reproductive system are the penis, the scrotum and the testicles. Penis — The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis.

Gonad Gonad: Gonad,, in zoology, primary reproductive gland that produces reproductive cells (gametes). In males the gonads are called testes; the gonads in females are called ovaries. (see ovary; testis). The gonads in some lower invertebrate groups (e.g., hydrozoans) are temporary organs; in higher forms they are permanent.

- The testes are known as gonads. Their female counterpart are the ovaries. In addition to their role in the male reproductive system, the testes also have the distinction of being an endocrine gland because they secrete testosterone—a hormone that is vital to the normal development of male physical characteristics.

Gonadal hormone Full Text. The gonad is the organ that makes gametes. The gonads in males are the testes and the gonads in females are the ovaries. Both gonads in males and females are endocrine glands. The ovary is a paired, ovum-producing, reproductive organ located in the lateral wall of the pelvis in a region called the ovarian fossa.

Chapter 28 Reproductive System The systems involved in an adequate sperm count, correct pH and nutrients, and erection and ejaculation are. reproductive and digestive, endocrine and nervous, and cardiovascular and urinary. The reproductive organs that produce gametes and hormones are the. gonads. In the male the important functions of the epididymis are. monitors and adjusts the composition of the tubular fluid, acts as a recycling center for damaged spermatozoa, the site of physical maturation of spermatozoa.

The Male Reproductive System The external structures of the male reproductive system are the penis, the scrotum and the testicles. Penis — The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis.he organs of the male reproductive system are specialized for the following functions: 1  To produce, maintain and transport sperm (the male reproductive cells) and protective fluid (semen). 2  To discharge sperm within the female reproductive tract. 3  To produce and secrete male sex hormones.

21.3 Differentiation of the gonads 21.3 Differentiation of the gonads. Descent of the testes. Between the 3rd month of pregnancy and its end the testes become transferred from the lumbar area (ventro-medial to the mesonephros) into the future scrotum. This transfer is due to a combination of growth processes and hormonal influences (7). The gubernaculum testis also plays a decisive role in this phenomenon.

Top 30 Doctor insights on: Can Gas Cause Testicle Pain The testicles are the two oval male gonads, or reproductive glands, located in the scrotum. The seminiferous tubules of the testis are the site of spermatogenesis and its leydig cells secrete testosterone. The term testicles is synonymous with testes or gonads. The singular form is testis, testicle, or gonad.

Fertilization Cells that develop in the yolk sac and migrate to the genital ridge (developing gonads). They arrest in the male but undergo mitosis to form oogonia in females. Cells produced by the mitosis of primordial germ cells at sexual maturity in the male. These cells also undergo mitosis to form primary spermatocytes.

- In males, the gonads are the testes. Their corresponding hormones  include:   Testosterone-This stimulates spermatogenesis, growth, and  maturation of sperm as well as the production of secondary sex  characteristics.  Inhibin-This hormone inhibits the secretion of follicle  stimulating hormone.     In males, the gonads are the testes. Their corresponding hormones  include:   Testosterone-This stimulates spermatogenesis, growth, and  maturation of sperm as well as the production of secondary sex  characteristics.
