How does the body react during fertilization?

Men have stronger physical desires when they are young, so after the body generates physical desires, the penis will become erect. When a boy's physical desires are unbearable, ejaculation is the only way to relieve his desires after his penis is erect. If there is no contraceptive measure, the male's sperm will enter the female's body. If the sperm and egg meet and ejaculate, what will happen to the female body?

1. The body's response during fertilization

1. There is generally no reaction during the fertilization process and the implantation of the fertilized egg. After the sperm enters the vagina, it can survive for 2-3 days. If ovulation occurs during this period, conception will occur. The lifespan of an egg is also about 2-3 days, while it takes one day for sperm to travel from the vagina to the fallopian tube, and two days for the fertilized egg to implant. Therefore, the time for conception after sexual intercourse should be 2+1=3 days. Pregnancy can only be considered after the fertilized egg successfully implants in the uterus. On the fourth day, the physiological reactions of pregnancy have just begun. The enzyme system during pregnancy has not yet been activated and the metabolites have not yet accumulated. The detection sensitivity of the test paper cannot achieve a clear distinction effect. After 3 weeks, you can use the test paper to judge.

2. What should be paid attention to when the fertilized egg implants?

In order to ensure successful conception, you must pay attention to the following aspects when the fertilized egg implants.

1. Do not take over-the-counter medicines at will. Taking any medicine during implantation may cause fetal malformation. Therefore, if you feel unwell during implantation, you should go to the hospital immediately to find out the cause.

2. During the implantation period, you should avoid lifting heavy objects or strenuous exercise, and reduce housework and outings as much as possible. Avoid overwork, get more rest, get enough sleep, and control your sexual life to avoid accidental miscarriage.

3. Quit smoking and drinking. Drinking during implantation will delay fetal development and reduce fetal birth weight. Smoking during implantation can cause fetal malformations and increase fetal mortality. Therefore, you should quit smoking and drinking during implantation.
