Slide 1 - Tekstslide

Learning goals
  • At the end of the class you know the parts of the female reproductive system and what they do
  • You know how ovulation and fertilization works
  •  You know the misconceptions about the female reproductive system.

Slide 2 - Tekstslide

you are changing
During puberty you change a lot. Especially on the following levels:
1. Physical 
2. Emotional 
3. Social 

The features of people that tell us their gender are called sexual characteristics.

Slide 3 - Tekstslide

Physical changes of the woman
The sexual characteristics present at birth are called the primary sexual characteristics:
- Vagina and labia

The sexual characteristics that start appearing from about the age of ten onwards are called: The secondary sexual characteristics 
- Breasts have grown,
- Wider hips
- Reproductive organs will start to function.

Slide 4 - Tekstslide

Physical changes in men
The primary sexual characteristics:
- Penis and scrotum
- Testes

The secondary sexual characteristics:
- More muscular body,
- Deeper voice, 
- Beard and chest hair
- Reproductive organs will start to function.

Slide 5 - Tekstslide

Internal male reproductive system
  1.  Testes: Makes the sperm cells
  2. Scrotum: Protects testes and has a lower temperature, which is good for sperm cell production. 
  3. Epididymis: Temporary storage for sperm cells.
  4. Sperm duct: Transports the sperm cells.

Slide 6 - Tekstslide

Internal male reproductive system
5. Seminal vesicle: Adds fluid with nutrition to the sperm cells. 
6. Prostate: adds fluid to sperm cells. 
Fluids + sperm cells =  called semen.
7. Urethra: Transports urine + semen to outside.

Slide 7 - Tekstslide

Slide 8 - Tekstslide

external female reproductive system
External part of the female reproductive system is called the vulva.

Clitoris: is the pleasure center of the vulva.

Inner labia: Glands in the inner labia produce mucus during sexual arousal. This lubricates the entrance of the vagina so the penis can slide in easier. 

Slide 9 - Tekstslide

Internal female reproductive system
Ova = female sex cells
Ovum = egg cell

Slide 10 - Tekstslide

  • Ovulation in Dutch = eisprong
  • Ovulation = when a ripe egg cell is released by the ovary
  • Happens every 4 weeks
  • One week left ovary, other week right ovary
  • Egg cell lives 24 hours

Slide 11 - Tekstslide

Slide 12 - Video

Fertilization - when sperm cell enters egg cell

Slide 13 - Tekstslide

When an egg is not fertilised, part of the uterus lining detaches. This is called menstruation.

Average age for girls to start their menstruation is 13.

Slide 14 - Tekstslide

Slide 15 - Video

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

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

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

Slide 16 - Tekstslide

Vagina info
1. Never wash your vagina with soap!!
This can cause infections.

2. Discharge is normal (penises do it too)

3. G-spot is not a thing. Most of the time vagina's are not that sensitive.

4. Avoid touching the anus and afterwards the vagina or vaginal region (can cause UTI, blaasontsteking)
