Sperm retrieval is not affected by a mild fever, but if the fever is greater than 38°C, this needs to be reduced before sperm retrieval, and sperm retrieval should be avoided if medication has been used.
Generally speaking, a cold with a fever of 38°C or less has little effect on sperm quality. Nowadays, sperms are not only produced on the same day, but also stored in the epididymis when they are healthy, so the quality of sperms is not affected much, and artificial insemination uses sperms that are highly active in them.
However, if you have a fever of more than 38℃, the rise in body temperature may affect the activity of sperms, so generally, if the fever is more than 38℃, it is necessary to carry out antipyretic and other treatments, and wait for improvement before sperm retrieval. Some medications have a greater effect on sperm, so if medications are used, it is necessary to wait for a period of time until the concentration of the medication decreases before performing sperm retrieval.
If there is any discomfort during sperm retrieval, it is recommended that the patient consults the doctor in time to decide whether or not the sperm can be retrieved according to the patient’s own situation.
