What is the best treatment option to achieve pregnancy with teratozoospermia?

By Zaira Salvador B.Sc., M.Sc. (embryologist).

Once teratozoospermia has been diagnosed with a semen analysis, there are the following alternatives for having children of one's own:

Artificial insemination (AI)
in cases of mild teratozoospermia and in women under 35 years of age. It is the simplest option for a first attempt.
In vitro fertilisation (IVF)
when the teratozoospermia is moderate or severe, and if the woman is over 35 years old.

On the other hand, IVF in men with teratozoospermia is usually performed by intracytoplasmic sperm injection (ICSI). There is also a newer technique: IMSI.

IMSI is a variant of conventional ICSI in which it is possible to observe the sperm at 6,000x magnification under the microscope. In this way, all sperm with any malformation are discarded and those with a perfect appearance for fertilisation are used.
