Reproduction in Humans

In Vitro Fertilisation

1 in 8 couples worldwide have difficulty conceiving a baby to start or grow their family. In the last 40 years, more than 50 million babies were born through IVF! Observe how fertilisation, which usually occurs in the mother’s body, takes place in a laboratory. Which part of the female reproductive system do you think the incubation chamber where the sperm meets the egg mimics?

Vasectomy

Tubes called the vas deferens transport sperm from the testes to the urethra – another tube that carries sperms and urine through and put of the penis. During a vasectomy, the vas deferns are cut and sealed, preventing sperm from being transported from the testes to the penis. 

Tubal Ligation

During tubal ligation, both fallopian tubes are cut and sealed to prevent sperm cells from reaching the egg for fertilisation to occur. This is a type of sterilisation which causes the female to no longer be able to have children.
