Does canola oil affect sperm?

Under normal circumstances, rapeseed oil has no effect on sperm and does not cause male infertility. The details are as follows:

Rapeseed oil is a type of edible oil extracted from rapeseeds and is one of the primary cooking oils in China. It contains polyunsaturated fatty acids such as linoleic acid and oleic acid, which are beneficial to health when consumed in moderation. Rapeseed oil is also rich in vitamin E and other antioxidants that help protect cells from oxidative stress damage. It is generally considered that rapeseed oil does not affect sperm, so men who are preparing for pregnancy need not worry excessively and can consume it as part of a normal diet. It should be noted, however, that sperm health and function are influenced by various factors, including diet, lifestyle, environmental exposures, and genetics. For those concerned about sperm health or fertility, it is recommended to maintain a balanced diet, exercise regularly, quit smoking, avoid alcohol, and refrain from staying up late, as these measures can generally improve sperm health.

It should also be noted that rapeseed oil is high in fat, so intake should be moderate to prevent obesity. Individuals experiencing discomfort should seek medical attention promptly and receive standardized treatment under a doctor's guidance, which can aid in recovery.
