Frequently Asked Questions
What is amniocentesis and why is it misused?
Amniocentesis is a prenatal diagnostic technique using amniotic fluid to detect genetic disorders. It is often illegally misused for female foeticide after sex determination.
What is the difference between ZIFT and GIFT?
ZIFT involves the transfer of a zygote or early embryo (up to 8 blastomeres) into the fallopian tube, whereas GIFT involves transferring an ovum collected from a donor into the fallopian tube of another female who cannot produce one.
Are all STIs completely curable?
No. While infections like gonorrhoea, syphilis, and chlamydia are completely curable if detected early, infections like Hepatitis-B, genital herpes, and HIV are currently not curable.
