In Vitro Fertilization (IVF); IVF 

Infertility is the inability to naturally conceive, carry or deliver a healthy child. The International Council on Infertility Information Dissemination (INCIID) considers a couple to be infertile if they have not conceived "after a year of unprotected intercourse in women under 35, or after six months in women over 35", or if they are incapable of carrying a pregnancy to term.

IVF (in vitro fertilization). Involves extracting a woman''s eggs, fertilizing the eggs in the laboratory, and then transferring the resulting embryos into the woman''s uterus through the cervix. For some IVF procedures, fertilization involves a specialized technique known as intracytoplasmic sperm injection (ICSI). In ICSI a single sperm is injected directly into the woman''s egg.
