An important factor in achieving pregnancy is the quality of the sperm, which can be assessed by performing a semen analysis. If the quality of the sperm is not correct, it will be necessary to resort to assisted reproduction techniques to achieve a pregnancy.
One of the options is IVF and it is usually indicated when the male presents an altered semen analysis. Some of the sperm alterations are the following:
- low concentration of spermatozoa in the semen sample.
- poor sperm motility.
- abnormal forms of spermatozoa.
Azoospermia: when there are no spermatozoa in the ejaculate.
