Oligospermia, also known as Oligozoospermia, is a medical symptom of low sperm count affecting men. It is defined as having less than 20 million spermatozoa per ml of ejaculate. Oligospermia has many different causes, as many different medical conditions can reduce sperm concentration. The effects of these causes may be temporary or permanent.


There is really no effective medication available today for increasing sperm count[1]. Nevertheless, clomiphene citrate, HMG and HCG injections are commonly used in lack of anything better.[1]

Other commonly used, but basically ineffective[1] medications are: ProXeed, testosterone, Vitamin E, Vitamin C, anti-oxidants, high-protein diets, hoemeopathic pills , ayurvedic churans and even varicocele surgery. That they have no real effect on oligospermia is a reason to that there are such many medications in use.[1]

Rather than medication, other assisted reproductive technology need to be used, such as IVF or even ICSI.[1]


Causes include:

  • Y chromosome microdeletion[1]

However, it is independent on physique, general state of health, diet, libido or sex frequency[1].
