A low s***m count, also called oligozoos***mia, is where a man has fewer than 15 million s***m per millilitre of semen. Having a low s***m count can make it more difficult to conceive naturally, although successful pregnancies can still occur. Problems with s***m, including a low s***m count and problems with s***m quality, are quite common. They're a factor in around 1 in 3 couples who are struggling to get pregnant.
Symptoms of Low S***m Count
The main sign of low s***m count is the inability to conceive a child. There might be no other obvious signs or symptoms. In some men, an underlying problem such as an inherited chromosomal abnormality, a hormonal imbalance, dilated testicular veins or a condition that blocks the passage of s***m may cause signs and symptoms.
Low s***m count symptoms might include:
* Problems with s*xual function β for example, low s*x drive or difficulty maintaining an er****on (erectile dysfunction)
* Pain, swelling or a lump in the testicle area
* Decreased facial or body hair or other signs of a chromosome or hormone abnormality.
