In the complex process of human reproduction, the union of sperm and egg is undoubtedly the magical moment when life is born. The testicles in the male body, as sperm production factories, operate efficiently every day, producing hundreds of millions or even billions of sperm. These sperm enter the woman\’s vagina through ejaculation and begin their long journey. They must travel through the cervix, uterine cavity, and ultimately to the fallopian tubes, where sperm and egg meet and fertilization may occur.
At the same time, a woman’s body is also preparing to welcome the arrival of new life at its own pace. A woman\’s menstrual cycle averages 28 days, but this cycle length can vary between women and within the same woman. Ovulation is a critical part of this cycle and usually occurs about 14 days before the next menstrual period. During ovulation, mature eggs are released from a woman\’s ovaries, waiting to meet sperm. 
Number of eggs Far fewer than sperm, and their survival time is short, only about 12 to 24 hours. If no sperm is encountered during this time, the egg will die naturally. This means that although there are many sperm, the chance of sperm and egg meeting and fertilizing is highest only during intercourse during ovulation.
Female fertility is also affected by many factors such as age, health, and lifestyle habits. As women age, their ovarian function gradually declines, and the frequency and quality of ovulation are also affected. Therefore, it is crucial for couples planning a pregnancy to understand a woman\’s menstrual cycle and ovulation. By monitoring basal body temperature, using ovulation test strips, or tracking changes in cervical mucus, couples can more accurately determine ovulation and thus choose the best time to have intercourse to increase the probability of pregnancy. At the same time, maintaining a healthy lifestyle, a reasonable diet and appropriate exercise can also help improve fertility. For example, it is beneficial to avoid smoking, limit alcohol consumption, maintain an appropriate weight, and have a balanced nutritional intake. In addition, reducing stress and anxiety can also help improve the fertility environment and make the body more conducive to pregnancy.
In short, the combination of sperm and egg is a key step in the beginning of life, and a woman’s menstrual cycle and ovulation period are important factors in determining the timing of pregnancy. Through scientific monitoring and planning, couples planning pregnancy can increase their chances of successful pregnancy and welcome the arrival of new life together. At the same time, maintaining a healthy lifestyle and a positive attitude are also important cornerstones for realizing fertility wishes.
