Reasons that affect semen quality can be summarized as follows:
- Exposure to radiation, such as radiation workers, patients receiving radiation therapy.
- Varicose veins, which extend the veins around the testes, which causes the heat around the testicles and the descent of substances that hinder the production and movement of sperm.
- A hormonal imbalance such as male hormone deficiency, thyroid hormone or increased prolactin hormone.
- Taking drugs that inhibit the work of the testicles, such as cancer-fighting drugs.
- Exposure to extreme heat such as standing in front of high-temperature furnaces.
- Smoking.
- The presence of antibodies in the blood against sperm.
