What is oligoteratozoospermia?
Oligoteratozoospermia is a semen alteration that consists of the combination of alterations in the concentration and morphology of the spermatozoa. The World Health Organization (WHO) establishes that a semen sample must have at least 15 million sperm per mL of ejaculate or a total concentration greater than 39 million. In addition, the sperm morphology must be greater than 4%.
If a seminal sample has low sperm count and also has abnormal sperm shapes, pregnancy in a natural way will be complicated. In this situation, it is most likely that assisted reproductive techniques such as IVF-ICSI will have to be used.
