Dilution of sperm by water does not lead to pregnancy in most cases and there is only a small chance that it will. Sperm may remain active for some time after leaving the organism if present in the semen, but may become inactive if diluted with water. Therefore sperm diluted with water will not be able to combine with the egg due to inactivation and most of the cases will not lead to pregnancy. However, there are a few cases where there is only a small amount of water in a large amount of semen. Some of the sperms may be inactivated, and some of the sperms, which are not exposed to water due to the protection of the semen, are still viable, and may be able to successfully unite with the egg. Pregnancy is not only related to the sperm, but also to the quality of the egg. If the quality of the egg is poor, even if the sperm is not diluted with water, the possibility of pregnancy is still low. If there is a need to get pregnant, it is recommended to do so under the supervision of a doctor.
