Reproductive System Overview

The male and female reproductive systems each include gonads, ducts, and accessory glands or organs. In males, the testes produce sperm which is expelled during ejaculation. In females, the ovaries produce eggs which travel through the fallopian tubes to the uterus, and the vagina connects to the exterior of the body. Key female organs are the ovaries, which produce eggs and hormones, the uterus which nourishes a fetus, and the cervix which connects the uterus to the vagina. The reproductive cycles begin at puberty and allow for both reproduction and sexual pleasure.

Human Reproductive system

Reproductive system includes;


-Gonads (testes, ovaries)

-Ducts

-Accessory glands and organs

- External genitalia

Males and females


 Males
 Testes produce spermatozoa
 Expelled from body in semen during ejaculation
 Females
 Ovaries produce oocytes
 Immature ovum
 Travels along uterine tube toward uterus
 Vagina connects uterus with exterior of body

Female Reproductive system


Female reproductive organs are for
intercourse, reproduction, urination
pregnancy and childbirth.

Ovary(Ovaries)

- Two solid egg-shaped structures

- They are attached to the uterus by ligaments. They are the counterpart of the male testicles.

- Ovaries have two main functions:

Ova

- The female reproductive cell.

- They are the largest cells in the female body. (about the size of a grain of sand.)

- The female baby is born with all the ova she will ever have (about 200,000 in each ovary).

- About 400-500 ova mature and are released over a lifetime


Estrogen

Estrogen is responsible for the secondary sex characteristics and the sex drive in females. It spurs the onset of
puberty and is responsible for OVULATION.

Progesterone
Progesterone builds up the lining of the uterus called the endometrium in preparation for the fertilized ovum

Ovulation
- When the egg is released from the ovary.

- At the age of puberty

- The ovum moves to the surface of the ovary in bursts out

- The ova falls into the fallopian tube and waits for fertilization

- This happens every 28 days

th
- It happens at about the 14 day of the cycle

Uterus
- A hollow, muscular organ (shaped somewhat like an upside-down pear, about the size of a fist).

- The uterus is lined with endometrium (a blood lining.)

- The uterus has one main function—to protect and nourish a fetus

- The walls of the uterus have the ability to stretch to the size of a small watermelon.

- After childbirth the uterus shrinks back to the original shape in 6-8 weeks, but it can take up

Cervix

 The neck or opening of the uterus.


 A normal healthy cervix is the strongest muscle in the body.
 It dips down about half an inch into the vagina.
 It is normally plugged by mucus. It stays tightly closed during pregnancy, but thins and opens for the
delivery of the baby.
 How big does it need to dilate to for birth?

Urethra The opening to the bladder


Clitoris
A small, pea shaped bump at the front of the labia.

- It contains a small amount of erectile tissue.


- The clitoris increases sexual pleasure

Time line :
 Ages 9-12
 Secondary sex characteristics appear
 Ages 11-14
 Menstrual cycle begins
 Late 20-30's
 Peak sexual urges
 Ages 45-55
 Menopause (cycle stops, but sex urge continues)

Male Reproductive
Male reproductive organs are for intercourse, reproduction and urination

Time Line:
 Infancy
 Erections begin
 Ages 11-14
 Secondary sex characteristics appear
 Ages 13-16
 Sperm produced in adult amounts (puberty)
 Late teens
 Peak sexual urges for boys
 Throughout life
 If good health is present, there is the sex urge and ability to father children
