Suggested when there is a male infertility problem in cervical mucous antibody reactions. This is doneusing a prepared semen sample from the husband. In cases where a donor sample needs to be used, the couple’s identifiable characteristics are matched as closely as possible with that of a donor.

In this technique, despite the best precautions, it may not be possible to completely rule out multiple pregnancy.
This procedure is advocated when the male does not have sperms in the ejaculate but has sperms in the testicular tissue or in the aspiration from the epididymis. We retrieve the sperm mechanically and follow it up with ICSI as described earlier. These two sperm retrieval techniques have revolutionized the treatment of male factor problems.
Excess embryos of good quality are frozen following IVF program, for future use up to a period of tenFrozen Embryo Transfer years. The big advantage of this procedure is that it involves the minimum of medical intervention. Next time round, there are no more daily injections to stimulate ovaries to produce follicles, so there is less stress on the patient. When the couples decide on a second child, the frozen embryos after thawing can be replaced in the uterus in a stimulated or natural cycle. Of course this procedure is adopted only after thoroughly briefing the couple and getting their consent.
A part of the IVF program is used to identify embryos with genetic material that may lead to fetal abnormalities. A single cell from each embryo is taken and the DNA is examined using genetic probes. Here the sex chromosome comes in for special scrutiny that helps to identify hereditary diseases that could be passed onto the fetus. This allows measures that could prevent it from happening.
