Question

(b) Describe the 'in vitro fertilisation' technique of reproduction in humans.

Answer 1

The invitro fertilisation technique help the women with blocked oviducts in having babies as follows:

• The eggs are removed from the ovary of woman by laproscopy.
• The woman's husband provides the sperms (in the form of semen).
• The sperms are mixed with eggs in a glass dish (or glass test-tube) to carry out fertilisation. The fertilised eggs (or zygotes) develop into embryos.
• After about a week, one or more embryos are placed in the woman's uterus (or womb). If the embryo gets implanted in the uterus successfully, then normal pregnancy occurs and a baby is born.
