The Chinese article titled "Can I have sex during ovulation" is as follows:

Sexual behavior is an integral part of human life, and the quality of sexual behavior directly affects the physical and mental health of two people. However, for couples who want to conceive, how to have intercourse at the right time becomes a problem.

Generally speaking, women's menstrual cycles are divided into two types: cycle length. Long cycles are called irregular menstruation, while short cycles are called irregular menstruation. Generally speaking, a woman's menstrual cycle lasts about 28 days, but some people may delay or advance their menstrual cycle due to factors such as malnutrition, disease, drugs, etc.

The ovulation period in women refers to the period between the 14th and 20th days of the menstrual cycle. During this time, a woman's eggs begin to mature and are expelled from the body. If she wants to become pregnant, she must have sexual intercourse during this time.

However, some people may miss the best time for intercourse due to the following reasons:

1. Irregular menstruation: Some people may have erratic menstrual cycles, causing them to be unable to accurately predict the best time for sexual intercourse.

2. Pregnancy: If a couple has been married for many years but has not yet become pregnant, some tests may be needed to determine if there is a fertility problem.

3. Disease: Certain diseases may cause changes in a woman's cycle, such as anemia, depression, etc.

4. Medications: Certain medications may cause changes in a woman’s cycle, such as antibiotics, antidepressants, etc.

The above Chinese article titled Is it possible to have sex during ovulation provides some basic knowledge on how to have intercourse at the right time. However, for couples who want to conceive, the time and manner of sexual intercourse are very important. It is recommended that couples communicate in detail before sexual intercourse, choose a comfortable sexual intercourse position as much as possible, and avoid excessive force and excitement to ensure the quality and safety of sexual intercourse. If a couple is unable to have intercourse at the right time, it is recommended that they seek help from a doctor to determine the best time for intercourse.
