No topic, just answer the following questions - Assignment Example After maturity, the sperm cells move along the vas deferens (Chiras 115-120). As the sperm cells move along the tube, they take fluid from seminal vesicles, prostate gland, and Cowper’s gland organs. The fluid is added to the sperm cells. The resulting mixture is known as semen. The fluid plays a significant role to the sperm cells. It provides nourishment to the cells, allows locomotion, and offers a suitable environment for the cells to exist. Exit of sperm occurs through a method identified as ejaculation (Chiras 115-120). However, ejaculation occurs when the male organ erect. Erection occurs once the male organ is filled with blood, and this makes it firm. As a result, semen is discharged through the tube known as the urethra. The tow cycles play a significant role in the reproduction process of a woman. A reflection on the two cycles is crucial. First, female ovarian cycle controls growth of the egg in the ovary. The process begins with the rise of level of estrogen in the woman body. Then increase level of this hormone causes an upsurge of luteinizing hormone (LH) and follicle Lutenising hormone (FSH) (Sloane 82-88). A rise of LH and FSH leads to growth and breakdown of the follicle, and this sets free the completely developed egg from the ovary. The menstrual cycle takes over the process from here. The process occurs in what is known as luteal phase. In the course of ovulation, the eggs disintegrate from its follicle (Sloane 82-88). However, the ruptured follicle floats on the ovary. For a period of 14 days, the follicle changes into a structure recognized as corpus luteum (Sloane 82-88). The structure plays a role of releasing progesterone and a limited amount of estrogen. The hormone helps in thicken ing of the uterine wall awaiting implantation of fertilized egg. Failure of egg to stick leads to various changes in the uterus. First, the corpus luteum shrinks and dies (Sloane
