Frequently Asked Questions
What is the difference between ZIFT and GIFT?
In ZIFT (Zygote Intra Fallopian Transfer), the zygote or early embryo up to 8 blastomeres is transferred into the fallopian tube. In GIFT (Gamete Intra Fallopian Transfer), unfertilized oocytes and sperm are transferred directly into the fallopian tube of a female who cannot produce eggs.
Why is amniocentesis legally banned in India?
Amniocentesis is a medical procedure used to detect chromosomal abnormalities and genetic disorders in the foetus. However, it is legally banned for sex determination to prevent female foeticide and maintain the child sex ratio.
Arebarrier methods completely effective against STIs?
Barrier methods like condoms provide good protection against many STIs and HIV because they prevent the direct contact of bodily fluids, unlike hormonal contraceptives or IUDs which only prevent pregnancy.
