• During this lesson you will learn about the menstrual cycle and the functions of hormones
• During this lesson you will understand how fertilisation and conception occurs and the development of the embryo and foetus.
• During this lesson you will understand the baby’s support system including the placenta, amniotic sac and fluid, cervix, umbilical cord and uterus.

Reproduction
The following video clip describes reproduction, hormones, puberty, development of the foetus and the babies support system.
The video clip will last approx 20 minutes, please take notes as this will assist you throughout the rest of this topic.

Draw and label the diagram, writing an explanation to the function of each part.
The female reproductive organ

Funnel Ovum

The Menstrual Cycle The function of the menstrual cycle is to release an egg and prepare the uterus to receive it if it’s fertilised. The cycle can vary enormously from person to person and month to month due to factors such as stress, diet, health, age, etc.

The male reproductive organ

Seminal Vesicle
EpididymusForeskin

Producing and releasing sperm
• Sperm is produced by the testes and stored in the epididymis.
• At ejaculation, sperm is released and rushes through the ducts.
• As it passes along the tube, the prostate gland and the seminal vesicles release seminal fluid, which nourishes the sperm
• The mixture of sperm and seminal fluid is a milky white fluid called semen
![Page 11: Year 10 Child Development Lesson 7 ~ Reproduction.](https://reader036.fdocuments.in/reader036/viewer/2022081515/56649f0d5503460f94c2175a/html5/thumbnails/11.jpg)

Hormones
• The period of change from childhood to adulthood is called puberty.
• During puberty hormones (chemical messengers) are produced from endocrine glands whose job it is to signal changes within the body that transform a person from a child to an adult.
• The hormone that triggers the male sex organs is testosterone.
• The hormone that triggers a female sex organ is oestrogen.
• Progesterone works in conjunction with oestrogen to control the menstrual cycle. It is also the pregnancy hormone.

Male or Female?

Reproductive System
![Page 15: Year 10 Child Development Lesson 7 ~ Reproduction.](https://reader036.fdocuments.in/reader036/viewer/2022081515/56649f0d5503460f94c2175a/html5/thumbnails/15.jpg)
Conception
• In order to become pregnant an egg must be fertilised by sperm.
• When sperm is ejaculated from the penis it swims towards the cervix, through the fallopian tube until they meet an egg.
• The sperm then fertilises the egg (CONCEPTION)
![Page 16: Year 10 Child Development Lesson 7 ~ Reproduction.](https://reader036.fdocuments.in/reader036/viewer/2022081515/56649f0d5503460f94c2175a/html5/thumbnails/16.jpg)
Ovulation and Fertilisation
• In the female, one of the ovaries produces an egg every 28 days. This is called ovulation.
• During sexual intercourse millions of sperm are ejaculated into the vagina.
• If a sperm meets the egg, the sperm’s nucleus can join with the egg’s nucleus.
• This fusing of the nuclei is called fertilization.

Your first photograph was probably taken when you were10-12 weeks old.
You already looked human and you were about to start gaining mass faster than you ever will again.
Your first photo?
Your head diameter was measured to check your age and make sure you were growing properly.
