Describe test tube baby programme.
In the Test Tube Baby programmes, ovum from the wife or a donor female and the sperms from the husband or a donor are collected and allowed to fuse under simulated conditions in the laboratory to form zygote; it is called In-vitro fertilisation (IVF). The zygote or early embryo is transferred into the uterus or fallopian tube for further development; this process is called Embryo Transfer (ET) and can be done in the following ways :
(i) The zygote or embryo upto eight blastomeres is transferred into the fallopian tube;this process is called Zygote Intra Fallopian Transfer (ZIFT).
(ii) Embryos with more than eight blastomeres are transferred into the uterus by the process called Intra Uterine Transfer (IUT).
