1. Assisted reproductive technologies
Infertility is the inability of a couple to have a baby
There are many potential causes:
Inability of the man to produce enough sperm
An imbalance in the hormones of the woman
Chemotherapy or other “hostile” medical treatments

2. Artificial insemination
This can solve infertility if the issue is the sprem count in the male
It is any process of collecting sperm from the male, possibly concentrating the sample to have a higher ratio of sperm to semen, then injecting it into the female
This has been used for 200 years to breed farm animals like dairy cows

5. In Vitro Fertilization
“in vitro” means in a glass.
This is best known for creating “test tube babies”
This can be used to solve issues that prevent the sperm and egg meeting (such as blocked fallopian tubes)
Eggs are removed from the woman and mixed with sperm in a lab. The resultant fertilized embryos will then be implanted in the uterus of the woman

6. To increase the chances of at least one fertilized egg surviving, more than one will be implanted
This can lead to multiple births
To help the implanted egg grow the woman must take hormones

8. Gamete Intrafallopian Transfer
Similar to IVF in that eggs are removed from the woman and mixed with sperm in the lab
Different from IVF because this mixture is immediatly injected into the fallopian tubes of the woman so fertilization occurs inside the woman

9. Intracytoplasmic Sperm Injection
A sperm cell is injected directly into the egg
The resulting zygote is then implanted into the woman
About 25% of ICSI procedures result in birth
