Research indicates warmer weather may enhance the chances of conception through IVF.

Study suggests summer months boost IVF success rates

A study involving 1,100 women undergoing IVF treatment suggests that pregnancy rates significantly increase during warmer months. Results indicate a pregnancy may be twice as likely when weather conditions are sunny, particularly when temperatures reach between 26 and 30 degrees Celsius. The research was conducted in China, focusing on patients at a fertility clinic from June 2021 until October 2023. Researchers observed that spring also showed improved rates, with a 75 percent increase in pregnancy compared to colder months. The findings propose that fertility clinics might consider scheduling treatments in alignment with seasonal variations to optimize IVF success.

Key Takeaways
