Answer:
Many couples all over the world are unable to produce children because of various reasons like congenital diseases, drugs, immunological and psychological factors. Such couples can be assisted to have children through techniques called assisted reproductive technologies (ART). IVF is one such ART and includes the following techniques:
• ZIFT - It stands for zygote intrafallopian transfer. In ZIFT, the sperm from a donor male and the ova from a donor female are fused in the laboratory. The zygote so formed is transferred into the fallopian tube at the 8 blastomeres stage.
• IUT - It stands for intrauterine transfer. In this technique, embryos with more than 8 blastomeres are transferred into the uterus.
• Surrogacy - Surrogacy is another method which is used for women who face problem in implantation of the embryo in the uterus. In this technique, the donor of the oocyte is the woman itself who has a problem in implanting the embryo in the uterus. The collected oocyte is fertilized with the sperm of her husband in a test tube. The embryo which is obtained after fertilization is implanted in the uterus of another female who is called the surrogate mother.
• Sperm bank - It is a new concept which is similar to blood banks. Sperms are collected from the male donors after a thorough medical checkup and stored for future use. These sperms are used to fertilize the ovum of women and this fertilised ovum is implanted in the uterus of the same women.
