Outline 5 causes of infertility in man?

1. Low sperm count: A low sperm count, also known as oligospermia, can significantly reduce the chances of conception. This can be caused by various factors such as hormonal imbalances, genetic factors, infections, or lifestyle choices such as smoking and excessive alcohol consumption.

2. Abnormal sperm morphology: Sperm morphology refers to the size and shape of sperm cells. Abnormalities in sperm morphology can make it difficult for sperm to reach and fertilize an egg. This can be caused by genetic factors, hormonal imbalances, or exposure to toxins.

3. Erectile dysfunction: Erectile dysfunction, or the inability to achieve or maintain an erection, can make it difficult for a man to successfully engage in sexual intercourse and ejaculate. This can be caused by various factors such as stress, anxiety, underlying health conditions, or side effects of certain medications.

4. Varicocele: A varicocele is a swelling of the veins that drain the testicles. This can lead to decreased sperm production and quality, ultimately affecting fertility. Varicoceles are a common cause of male infertility and can be treated through surgery.

5. Hormonal imbalances: Hormonal imbalances, such as low levels of testosterone or high levels of prolactin, can affect sperm production and quality. These imbalances can be caused by various factors such as thyroid disorders, pituitary gland disorders, or certain medications. Treatment for hormonal imbalances can help improve fertility in men.
