What is the Factor known that can lead to male infertility?

Certain chemicals are known to negatively impact male fertility, making exposure to them a significant factor in male infertility. Various industrial chemicals, heavy metals, and endocrine disruptors can adversely affect sperm production and function. For example, exposure to pesticides, lead, and phthalates has been associated with reduced sperm counts and motility, as well as abnormal sperm morphology.

In contrast, while a sedentary lifestyle and elevated stress levels can also influence fertility, their direct impact is often less pronounced compared to chemical exposure. A sedentary lifestyle may contribute to weight gain and hormonal imbalance, which in turn could affect fertility, but it is not as direct a cause as exposure to harmful substances. Elevated stress levels can affect hormone levels and libido, potentially impacting fertility, but the effects are variable and can be managed through lifestyle changes. An adequate body weight typically supports overall health and can be beneficial for fertility. However, being within a healthy weight range alone does not directly prevent male infertility caused by toxic chemical exposure.
