31
Q

What is facilitated reproduction?

A

Using technology to increase the chances of pregnancy.

32
Q

Name the 2 common methods of facilitated reproduction.

A

1) in-vitro fertilisation
2) artificial insemination

33
Q

Describe how in-vitro fertilisation works.

There are 3 steps.

A

1) eggs and sperms collected from the couples
2) eggs mixed with sperms in a glass dish to allow fertilisation
3) fertilised eggs are released into the uterus for implantation

34
Q

Describe how artificial insemination works.

There are 2 steps.

A

1) healthy sperms are collected from the male
2) the sperms are released into the uterus to increase the chances of fertilisation

35
Q

State the 2 permanent birth control methods.

A

1) vasectomy (male)
2) ligation (female)

36
Q

Describe how vasectomy works to prevent pregnancy.

A

The sperm ducts are cut and tied back.
This prevents the sperm from entering the urethra.
No sperms will be deposited at the vagina.

37
Q

Describe how ligation works to prevent pregnancy.

A

The oviducts are cut and tied back.
This prevents the sperm from reaching the egg.
