week 11

• Estrogen is the hormone that regulates the menstrual cycle
• progesterone is the hormone that supports pregnancy.
• The ovaries are two small, oval-shaped glands located on either side of the uterus.
• They are home to the female sex cells, called eggs, and they also produce estrogen, the female sex hormone.

  ovaries
• The fallopian tubes are narrow tunnels for a fertilized egg to make its way down to the uterus.
• Damage or blockage to the fallopian tubes — called tubal disease — can sometimes cause fertility problems
• The uterus is a hollow, pear-shaped organ located in a woman’s lower abdomen, between the bladder and the rectum.
• It is also called the “womb” and holds the fetus during pregnancy.

  uterus
• The cervix is the lower, narrow part of the uterus, located between the bladder and rectum.
• It forms a canal that opens to the vagina.

  Cervix
• Often called the neck or entrance to the womb, the cervix lets menstrual blood out and semen into the uterus
• This is the external portion of the female genital organs.

  Vulva
• Your labia majora (“large lips”) enclose and protect the other external reproductive organs.
• During puberty, hair growth occurs on the skin of the labia majora, which also contain sweat and oil-secreting glands.
• Your labia minora (“small lips”) can have a variety of sizes and shapes
• They lie just inside your labia majora, and surround the opening to your vagina and urethra .

  Labia minora
• the canal that joins the lower part of your uterus to the outside of your body

  vagina
• the tube that carries pee from your bladder to the outside of your body

  urethra
• This skin is very delicate and can become easily irritated and swollen.

  Labia minora
• Your two labia minora meet at your clitoris, a small, sensitive protrusion that’s comparable to a penis in men or people assigned male at birth (AMAB).
• Your clitoris is covered by a fold of skin called the prepuce and is very sensitive to stimulation.
• Your vaginal opening allows menstrual blood and babies to exit your body. 
• Your hymen is a piece of tissue covering or surrounding part of your vaginal opening.
• It’s formed during development and present during birth.

  Hymen
•  The opening to your urethra is the hole you pee from.
• Testosterone is the main sex hormone in people AMAB (assigned male at birth).
• It helps you develop certain characteristics, including muscle mass and strength, fat distribution, bone mass and sex drive (libido).

  Testosterone
• The penis is made up of two parts, the shaft and the head.
• The urethral opening at the tip of the penis delivers sperm into the vagina during sexual intercourse.
• The scrotum is the sac-like organ hanging behind and below the penis
• It contains the testicles (also called testes), as well as many nerves and blood vessels.

  Scrotum
• The testes (oval organs that lie in the scrotum) are the primary male reproductive organ and are responsible for testosterone and sperm production.

  Testicles (testes)
• The epididymis is a C-shaped tube that rests on the backside of each testicle.
• It transports and stores sperm cells that are produced in the testes.

  Epididymis
• The epididymis also brings the sperm to maturity, since the sperm emerging from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens
• The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder.


  Ductus (vas) deferens
• The vas deferens transports mature sperm to the urethra, the tube that carries urine or sperm outside of the body, in preparation for ejaculation.
• These are formed by the fusion of the vas deferens and the seminal vesicles.

  Ejaculatory ducts
• The ejaculatory ducts empty into the urethra.
• The urethra is the tube that carries urine from the bladder to outside of the body.
