In fertilization, the organs that make up the reproductive system in males plays the role of producing and discharging sperm within the female reproductive tract. The penis, scrotum, testes, sperm, epididymis, and accessory organs make up the reproductive organs in a male. In addition to being used for sexual intercourse and the pathway for semen, the penis is also where urine is passed through. The scrotum is a pouch located below the base of the penis, with two compartments. The compartments of the scrotum hold the testes. Each testicle ...view middle of the document...
There are two Cowper’s glands located below the prostate. Secretions from the Cowper’s glands are emptied into the urethra, found at the top of the penis during sexual arousal, contains sperm, and precedes ejaculation.
Like the male, the organs that make up the reproductive system in the female are responsible for fertilization. The mons veneris, labia majora and minora, clitoris, vestibule, vaginal opening and the perineum are the external sex organs of the female reproductive system. Internal sex organs include, the vagina, cervix, uterus, fallopian tubes, and ovaries. The mons veneris is the fatty tissue covering the joint of the pubic bones that severe as a cushion to the woman’s body and protection to the woman and man from the pressure against the pubic bone, during sexual intercourse. The labia majora are large folds of skin that hide the labia minora, urethra and vaginal openings, and the inner genitals of the female. Nerve endings within the labia majora respond to stimulation and produce sexual pleasure. The labia minora contains blood vessels, nerve endings, and are very sensitive to sexual stimulation. When stimulated, they darken and swell, engorging with blood (Rathus & Fichner-Rathus, 2011). Much like the labia majora and minora, the vestibule is sensitive to sexual stimulation. The opening to the vagina and urethra is located within the vestibule. Separating the labia minora allows one to see the vaginal opening. The perineum contains nerve endings, skin and tissue between the opening of the vagina and the anus.
A woman’s vagina is a tubular sex organ that contains the penis during sexual intercourse, through which a baby is born, and is usually 3 to 5 inches long at rest (Rathus & Fichner-Rathus, 2011). Located at the lower end of the uterus is the cervix. It contributes to the chemical balancing of the vagina by producing secretions. The cervical canal allows sperm to pass from the vagina to the uterus. An ovum that has been fertilized implants and develops in the uterus until it is time for birth. Four inches in length and extending from the uterus to the ovaries are the fallopian tubes. The fallopian tubes act as a pathway to all ova to pass through to get to the uterus. They...
