उत्तर
In-vitro fertilisation (IVF): In this process, the fertilisation takes place outside the body (test tube baby). The following techniques are included in IVF:
- Zygote Intrafallopian Transfer (ZIFT) - In ZIFT, the sperm from a male donor and the ovum from a female donor are fused in the laboratory. The zygote so formed is transferred into the fallopian tube at the 8 blastomeres stage.
- Gamete Intrafallopian Transfer (GIFT) - In GIFT, females who cannot produce ovum, but can provide suitable conditions for the fertilisation of ovum, are provided with ovum from a donor.
