The chances of conceiving naturally for a teratozoospermic man are very low, if not nonexistent. In order to have biological offspring it is necessary to use assisted reproduction treatments.
The recommended techniques vary depending of the degree of affectation. Also, fertility and age of the woman are also taken into account, as the latter might be a limiting factor when attempting pregnancy.
Assisted reproduction treatments
Once the diagnosis of teratozoospermia is confirmed, the couple will start the treatment that meets their needs. The available options are:
- Artificial insemination (IA): recommended in cases of mild teratozoospermia (3%-4% of the spermatozoa are normal), provided that the woman is younger than 35.
- In vitro fertilisation (IVF): aimed at men with moderate teratozoospermia (1%-2% of spermatozoa are normal), mild teratozoospermic men whose partner is older than 35 or cases of multiple inseminations failures.
- ICSI: to be used in cases of severe teratozoospermia (less than 1% of normal spermatozoa) or if the techniques mentioned above have not been successful.
- IMSI: is a variation of ICSI with better sperm recruitment. In order to do so, a high-powered observation system allows the specialist to examine sperm in closer detail, identifying this with good morphologies and spotting abnormalities. Is the treatment of choice in cases of severe teratozoospermia or in a history of recurrent miscarriages.
