hi found you this answer on med help its from dr j m epp phd hi. here are the answers to your questions: 1. sperm cannot survive in hot water. however they can survive in cold or warm water for a few minutes. 2. they die very quickly once they get dry in the air are exposed to cleaning chemicals or change temperature too much. that means that when semen dries out the sperm inside are probably dead. according to the mayo clinic sperm in semen exposed to the open air will usually die within a few hours. you can also kill sperm on your hands clothes or bedding by washing them in soap and water. if you have semen on your body and need a quick clean up you can simply wipe it up with baby wipe or tissue so that the remaining semen dries quickly. the rest will probably dry in the trash long before you take out the garbage. please note that soap water or air are not effective forms of birth control if semen has gotten in or on your partner's genitals! i'm just talking about sperm that is outside the body. if there are diseases in the semen they may be more resilient depending on the disease. hopefully this information will put you at ease about the longevity of your delicate little swimmers. 3. washing your hands with very hot water and soap will kill sperm as long as you can be sure you've reached every tiny nook and cranny of your hands. a much more effective form of risk reduction is to use a barrier method such as latex. 4. varicose veins do not impair sperm production. 5. sperm begin to die on contact with air; however there are millions and millions in each ejaculation. take a drop of semen and put it on a piece of paper. as the semen dries out the sperm are dying. once the semen is totally dry the semen are all dead. that's the amount of time it takes for them all to die. the smaller the drop the quicker they're dead. dr. j do hope this helps you calm your nerves. good luck
if guy ejaculates on toilet and doesnt flush and min later girl pees water splashes on her vulva can she get pregnant? . a family member tends to never flush and i think he masturbates there. a couple of days ago i rushed to the restroom without checking if it was flushed and water splashed on my vulva. is there a chance of pregnancy? i don't know how long after i used the restroom but the toilet tab was opened so i am guessing the water was cold and there was air around. i am very worried since it was in my fertile days and i am not down for incest.
