Question

Answer

Some couples (with some special cases) could be assisted to have children through certain special techniques commonly known as assisted reproductive technologies (ART). Several techniques are available today, such as: in vitro fertilisation (fertilisation outside the body in almost similar conditions as that in the body) followed by embryo transfer (ET) is one of such methods. The zygote or early embryos (with up to 8 blastomeres) could then be transferred into the fallopian tube.

(ZIFT–zygote intra fallopian transfer) and embryos with more than 8 blastomeres, could be done into the uterus (IUT – intrauterine transfer), to complete its further development. Transfer of an ovum collected from a donor into the fallopian tube (GIFT – gamete intra-Fallopian transfer) of another female who cannot produce one, but can provide a suitable environment for fertilisation and further development is another method attempted.

Intracytoplasmic sperm injection (ICSI) is another specialised procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum.

Infertility cases either due to the inability of the male partner to inseminate the female or due to very low sperm counts in the ejaculates could be corrected by artificial insemination (AI) technique. In this technique, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus (IUI-intra-uterine insemination) of the female. After insemination of sperm into the female body, the next process is similar to the natural type.
