Does a Fever Affect Sperm Quality and Future Pregnancy?

Does a man's fever affect sperm quality?

Hello! We are a couple planning to conceive soon, but my husband had a cold with a fever that reached up to 104 degrees Fahrenheit a couple of days ago.
Today is the optimal time for conception.
I would like to know if conceiving now would affect the quality of the sperm produced during the fever and impact the fetus.
Thank you!

Dr. Wu Zongcheng reply Obstetrics and Gynecology

Dr.
Wu Zongcheng from the Department of Obstetrics and Gynecology at Tainan Hospital of the Ministry of Health and Welfare responded that if the husband has a fever, his sperm will certainly be affected, leading to reduced fertility.
However, as long as medication is taken with caution, it will not impact fetal malformations.
Given your situation, it is advisable to use contraception this cycle and try again in the next cycle.
Tainan Hospital wishes you good health and all the best.

Fever can indeed have an impact on sperm quality, which is a crucial factor when considering conception. When a man experiences a high fever, particularly one reaching 40 degrees Celsius (104 degrees Fahrenheit), it can lead to temporary changes in sperm production and quality. The testicles, where sperm is produced, are sensitive to temperature. Elevated body temperature can impair spermatogenesis, the process of sperm production, leading to a decrease in sperm count, motility (the ability of sperm to move), and overall viability.

Research indicates that fever can affect sperm parameters, and while the effects are often temporary, they can still be significant during the critical window of conception. If the sperm produced during a period of fever is used for fertilization, there is a possibility that the quality may not be optimal, which could potentially affect the chances of successful conception and the health of the embryo. However, it is important to note that the body typically recovers from such temporary impairments, and sperm quality can improve in subsequent cycles.

In your specific case, since your husband experienced a high fever just before your optimal conception period, it may be advisable to consider postponing attempts to conceive until after he has fully recovered and his body temperature has returned to normal for a few days. This would allow his body to produce healthier sperm, which could enhance the chances of a successful pregnancy and reduce any potential risks to the embryo.

Regarding the concern about the health of the fetus if conception occurs during a period of fever, it is generally understood that while sperm quality may be affected, the risk of congenital abnormalities or other issues related to the embryo is not significantly increased solely due to the fever. However, it is essential to consider other factors such as maternal health, environmental exposures, and lifestyle choices that can also impact fetal development.

In addition to fever, other factors such as the use of medications during illness, overall health, and lifestyle choices (like smoking, alcohol consumption, and diet) can also play a role in both sperm quality and fetal health. If your husband was taking medications to manage his fever, it is crucial to consult with a healthcare provider regarding any potential effects those medications might have on sperm quality.

In conclusion, while a fever can temporarily affect sperm quality, the impact on future pregnancy can be managed by allowing time for recovery and ensuring optimal health before attempting conception. It is always best to consult with a healthcare provider for personalized advice and to discuss any concerns regarding fertility and pregnancy. They can provide guidance based on your specific circumstances and help you make informed decisions about your family planning.
