More and more couples are turning to fertility clinics to find out why they are unable to conceive naturally. Male factors can account for many of these cases of infertility, although not all of them are equally well known. Among them is hypospermia, a condition related to semen volume.
Hypospermia refers to a decrease in the volume of ejaculated semen, below 1.5 milliliters after a period of sexual abstinence lasting between two and seven days, according to the criteria set by the World Health Organization (WHO).
This condition should not be confused with oligozoospermia (low sperm count) or asthenozoospermia (reduced motility). Hypospermia exclusively concerns the volume of the ejaculate.
There are several factors that can lead to hypospermia in men. In some cases, it is linked to insufficient production of seminal fluid in the accessory glands (prostate and seminal vesicles). In others, it may be caused by a partial obstruction of the ejaculatory ducts.
Other contributing factors include hormonal imbalances, neurological disorders that interfere with ejaculation, or even lifestyle habits such as dehydration, excessive alcohol consumption, or prolonged stress.

The standard test used to diagnose hypospermia is the seminogram or semen analysis. This is a simple and routine examination that measures not only semen volume, but also sperm concentration, motility, and morphology.
In some cases, fertility specialists may recommend additional studies such as ultrasounds or hormonal analyses to determine whether the underlying cause is anatomical, obstructive, or hormonal.
A reduction in semen volume does not necessarily mean that a man is infertile. However, it may hinder the efficient transport of sperm through the female reproductive tract.
If this reduction is combined with other factors, such as low sperm concentration, the chances of achieving a natural pregnancy can be further diminished. For this reason, hypospermia should be considered an alert sign warranting a complete fertility evaluation.
Addressing hypospermia requires treating its root cause. If it is related to a hormonal disorder, hormone therapy may be prescribed. When caused by an obstruction, surgery may be necessary to restore normal flow.
In some cases, hypospermia results from unhealthy lifestyle habits. Here, simple modifications such as improving hydration, reducing alcohol intake, and managing stress can improve semen parameters within weeks or months.

As mentioned, hypospermia can be treated in different ways to minimize its impact on male fertility, but treatment is not always successful. In such cases, assisted reproductive medicine provides alternatives, which vary according to the severity of each case.
For mild cases, artificial insemination may be sufficient if sperm quality is otherwise good. In more severe cases, or when hypospermia is associated with other alterations, in vitro fertilization (IVF) offers greater chances of success, as it allows for sperm selection and laboratory-based fertilization of the egg.
In any case, the final decision always depends on medical criteria. At IVF-Life, each case is assessed individually in order to select the most appropriate treatment.
When there is any suspicion of hypospermia or another alteration in semen parameters, it is essential to consult a fertility specialist as soon as possible. Early diagnosis makes it possible either to begin the most suitable treatment for each situation or to choose the most effective assisted reproduction technique if necessary.
In short, hypospermia is a factor that may influence male fertility, but it does not amount to a definitive diagnosis of infertility. Thanks to precise diagnosis and advances in assisted reproduction, many men with this condition are able to fulfill their wish of becoming fathers.
