REPRODUCTIVE DEVELOPMENT
Intrauterine Development
Pubertal Development
Role of Androgen
Role of Estrogen
The sex of an individual is determined at the moment of conception by the chromosome information supplied by the particular ovum and sperm that joined to create the new life.
Intrauterine Development
Is a body organ that produces the cells necessary for reproduction
Gonad
(the ovary in females, the testis in males)
Puberty is the stage of life at which secondary sex changes begin
Pubertal Development
Androgenic hormones are the hormones responsible for muscular development, physical growth, and the increase in sebaceous gland secretions that causes typical acne in both boys and girls.
Role of Androgen
When triggered at puberty by FSH, ovarian follicles in females begin to excrete a high level of the hormone estrogen
Role of Estrogen
Pubertal changes in girls
1. Growth spurt
2. Increase in the transverse diameter of the pelvis
3. Onset of menstruation
4. Growth of axillary hair
5. Vaginal secretions
6. Breast development
7. Growth of pubic hair
Pubertal changes in male
1. Increase in weight
2. Growth of testes
3. Growth of face, axillary, and pubic hair
4. Voice changes
5. Penile growth
6. Increase in height
7. Spermatogenesis (production of sperm)

Epididymis

Prostate Gland
Bulbourethral Glands
Urethra
is a rugated, skin-covered, muscular pouch suspended from the perineum. Its functions are to support the testes and to help regulate the temperature of sperm
Scrotum
Are two ovoid glands, 2 to 3 cm wide, that lie in the scrotum
Testes
is composed of three cylindrical masses of erectile tissue in the penis shaft: two termed the corpus cavernosa, and a third termed the corpus spongiosum
Penis
The seminiferous tubule of each testis leads to a tightly coiled tube, the epididymis, which is responsible for conducting sperm from the tubule to the vas deferens, the next step in the passage to the outside.
Epididymis
is an additional hollow tube surrounded by arteries and veins and protected by a thick fibrous coating.
Vas Deferens
is a popular means of male birth control
Vasectomy
are two convoluted pouches that lie along the lower portion of the posterior surface of the bladder and empty into the urethra by way of the ejaculatory ducts.
Seminal Vesicles
