What is infertility ? How is infertility treated by assisted reproductive technologies like GIFT and ICSI?

Explanation

An woman who is unable to conceive is called infertile . This infertility is caused due to defects in men or women or both .
Gamete intra fallopian transfer: Here both ova and sperms are trasnferred into the fallopian tube of the mother , when her both ovaries are defective . This leads to invitro fertilization (natural) . Here failure of fertilization and pregnancy amy happen . Even when cervial canal is narrow and cervical mucosa is hostile for sperm movement it is practiced
Intra cytoplasmic sperm injection(ICSI) : It is a technique in which a single healthy sperm is injected into each mature egg directly .ICSI increase the change of fertilisation for men who have low sperm count or poor sperm quality.
