Introduction Sexuel reproduction

Hormones are responsible for changes

• In the brain the pituitary gland (hypofyse ) produces hormones
• Hormones are transported in the blood stream 
• At the place of change tissue react 

Hormones

-Proteins
- Regulate functions 

- Coordinate processes in the body

- are produced in glands and secreted into the bloodstream

- travel in the bloodstream to target cells/organs --> key - matching lock- send slow, long-lived signals

-Puberty hormone (LH/FSH) 

From pituitary to puberty

Puberty hormone (LH/FSH) fits on 
target cells in ovary (testes )

Ovaries ( and testes )  
are now active!

transport of hormones

Clitoris and Labia

Labium minora/majora

clitoris
urethra

vagina (& hymen)

The external parts of the female reproductive system

vagina :entrance in the woman's body where semen is released during sexual intercourse

clitoris: area of skin at the front of the vagina that is sensitive to stimuli 

outer labia: folds of skin around the inner labia

inner labia: these folds of skin around the vagina have glands that produce mucus to lubricate the entrance to the vagina

Hymen : it is a small, thin piece of tissue at the opening of your vagina. 

The menstrual cycle

• After the menstruation the uterus linings starts to grow thicker again and have more blood vessels.

•  Ovulation start +- around 14 days after the start of the last menstruation.

• Next menstruation starts about 28 days after the start of the last one.

4 Phases

• Phase 1 (day 1-5) : menstruation
• Uterus lining is shed through the vagina (no fertilized egg)
  
  
• Phase 2 (day 6-12): repair phase
• uterus lining build new layer of mucus
• new egg cell develops in the ovary

4 Phases

• Phase 3: Ovulation (day 13-15)
• A new ova is released and send down the oviduct
  
  
• Phase 4: Receptive phase (day 16 - 28)
• Uterus lining grows to form a 'nest' for the egg cell
• No fertilized egg cell? --> cycle starts again!
