How long can sperm survive on sheets and quilts?

One: Sperm stays in the air and is infiltrated by oxides. It can only survive for 2- 15 minutes at atmospheric pressure, so the survival time of sperm in the air is relatively short. Sperm flowing out during excitement refers to the semen left around the vaginal opening before ejaculation. Sperm may have been left in the vagina during insertion. In this case, pregnancy is possible except the safe period. However, if there is no sexual behavior entering the vagina and the sperm stays around the vaginal opening, the chance of pregnancy is small. Therefore, sperm survive in the air for a short time.

Two: Sperm can live in vagina for 0.5 days. Survive in the cervix for 2 to 8 days and in the ovary for 2 to 2.5 days.

The survival time of sperm in women should be distinguished according to the specific location of sperm. The time between them is not exactly the same. For example, the survival time of sperm in vagina is only 0.5 days; Sperm in the cervix can survive for as long as 2 to 8 days; When sperm is in uterus or ovary, its survival time can be as high as 2 to 2.5 days. Moreover, the survival time of sperm in women is obviously related to the sex of sperm. Sperm can be divided into female sperm and male sperm. The survival time of male sperm is short, so the survival time of each part is shorter than that of female sperm. In addition, the survival time of male sperm and female sperm in women is also related to the surrounding specific conditions, such as whether there is a tumor in the reproductive tract, whether there is infection, and even whether there is tubal stenosis, which are obviously related to these diseases.
