  Reproductive System - MSN Encarta
The primordial germ cells remain inactive in the gonads until the animal reaches sexual maturity, when the undifferentiated cells undergo a great number of normal cell divisions or mitoses.
The size of gonads increases at sexual maturity because of the great number of germ cells produced at that time; many germ cells are also produced during breeding seasons so that many animals have a seasonal increase in size of the gonads.
The functioning of both male and female gonads is under the hormonal influence of the pituitary gland.

In males, the male gonads, known as the testes or testicles, secrete the class of hormones called androgens, and produce spermatazoa.
Gonads start developing as a common anlage, and only later are differentiated to male or female sex organs.
Gonads in human males are capable of producing two pints of spermatazoa in a single day.

In invertebrates, the primordial germ cells congregate in the body cavity or in a section of the circulatory system; in vertebrates, these cells are located in organs that adjoin the excretory system.

In peripheral regions of gonads a lot of oogonia and oocytes of early prophase meiosis stages were observed that in fact reflect the process of gonad recovery.
Visual analysis of the state of the gonads in the control and treated fishes of 194 days of age showed that,of 39 control females, 15 were at maturity stage 1Y; 24 had gonads with resorbing oocytes.
Gonads of 30 days age fishes are more stable to X-rays action that may possible be explained low radiosensitivity of previtellogenic oocytes and small proportion of oogonia and early prophase meiosis oocytes.

Starting with the anterior ends of the two lobes, slowly and carefully pull the gonad away from the abdominal wall until just the connected posterior end of the gonad remains.
If the gonad is thicker than 1/2" in cross-section, please cut into it, to the center and all along its length with the knife tip to allow better penetration of the preservative.
Pushing the knife-tip toward the lower (ventral) part of the fish and with the sharp edge of the knife pointing towards the fish's head, cut into the belly carefully, and continue cutting the skin towards the gills with a shallow-incision from the anus to the ventral base of the gill cover.

 "Descent" of gonads
In the female it remains longer, and is represented by fibrous cords - ligament of the ovary connecting the ovary to the uterus, and the round ligament which passes from the uterus to the labium majus through the inguinal canal.
Thus the gonadal arteries are paired branches of the aorta, the veins drain into the inferior vena cava (indirectly through the renal vein on the left side) and the lymphatics drain into lymph nodes lateral to the aorta.
In discussing the descent of the gonad, details of histological aspects of gonadal development are not expected.

When the fetal gonad is developing, primordial germ cells are moving and by E13 arrive at the genital ridge.
Differentiation of the male and the female gonads and the concomitant development of the gonocytes and oocytes involve intricate interaction of a large number of genes; the identity of the majority of these genes is still largely unknown.
The transcriptome of gonocyte is compared with that of type A spermatogonia as well as that of E13.5 male gonads to delineate the group of gene clusters that regulate differentiation of primordial germ cells to gonocyte and then to spermatogonia.

Male gonads, or testes (pronounced: tes-teez), secrete hormones called androgens (pronounced: an-druh-junz), the most important of which is testosterone (pronounced: teh-stass-tuh-rone).
These hormones regulate body changes associated with sexual development, including enlargement of the penis, the growth spurt that occurs during puberty, and the appearance of other male secondary sex characteristics such as deepening of the voice, growth of facial and pubic hair, and the increase in muscle growth and strength.
The female gonads, the ovaries (pronounced: o-vuh-reez), are located in the pelvis.
