What Is the Normal Semen Volume in Males?

When a semen analysis is performed to check the fertility of a man, a series of parameters of the sperm sample must be evaluated, including the ejaculated volume.

It’s important to check the quantity of semen ejaculated, since, even though it may not refer directly to the sperm count, it’s important to know the quantity of sperm that reaches the uterus.

The volume is measured in milliliters of ejaculated seme. The World Health Organization (WHO) considers that the reference value for a normal ejaculated volume should start from 1.5 ml. Higher values do not indicate any alteration. However, values below this figure indicate that the man has hypospermia.

The different sections of this article have been assembled into the following table of contents.

Male fertility alterations

The hypospermia causes male infertility, since it’s complicated that spermatozoa can reach the Fallopian tubes, if there’s less than 1,5 ml of ejaculated volume.

Quanity of sperm

Through the usage of assisted reproduction techniques, such as ICSI, in which few spermatozoa are required, men with hypospermia count on good odds to become fathers. Even though the ejaculated volume is inferior to 1,5 ml, a low quantity of spermatozoa is needed for this technique.

Another complication related with volume, which is more severe, is aspermia, in which the man is completely unable of expelling any fluid during ejaculation. In this case, the origin of this alteration should be found, to check if there’s spermatozoa production in the testicles.

Another possible alteration, even though it’s not related to any pathology, is hyperspermia. Men that suffer from it expel a high volume of fluid during ejaculation. It’s considered hyperspermia with more than 6 ml ejaculated volume. It doesn’t produce infertility, and it’s usually related with a big size of the seminal vesicles, since these are the organs responsible for more than 70% of the ejaculated volume.
