Silvia Azaña, an embryologist at inviTRA, explains in this video if hypospermia affects male fertility:
To correctly evaluate the seminal quality in a semen analysis, the patient must arrive with a sexual abstinence of 2 to 5 days. If there are fewer days of abstinence and the semen volume is lower than normal, it's possible that the hypospermia is due to this, to a recent ejaculation, and not to any major problems.
Likewise, it is essential that the seminal sample is collected in its entirety. If any part of the ejaculate has been lost, it's essential to inform the lab, since the collected volume doesn't represent the total volume of the ejaculate.
On the other hand, it's true that if a man has a low ejaculate, the total sperm count in the ejaculate may be lower than that of another man without hypospermia
Although hypospermia is most often related to oligospermia, or low sperm concentration, this is not always the case.
It can happen that the sperm count per milliliter is good and that they show adequate morphology and motility. Therefore, having hypospermia doesn't necessarily mean there's an infertility problem if the concentration, motility, and morphology of the sperm are adequate.
However, if when seeking pregnancy, hypospermia delays or prevents this goal, a lifestyle change could be tried or assisted reproduction techniques used.
