Question 1

how long does it take for left over sperm leave the urethra?

Accepted Answer

Here are some...: After a flush-out by urination, the urethra should become sperm-free although no practical study has been done specifically to address your Q. How soon do you pee? That will tell how long it takes to clean sperms out of urethra.

Question 2

how long can sperm stay in urethra after ejaculation?

Accepted Answer

: Some sperms which might linger in the urethra are washed away on urination.

Question 3

i have urinated 3 times since my last ejaculation. is all the sperm in my urethra removed?

Accepted Answer

: There is no way for you to know. Having repeated sex without condoms and contraception has the same risk for unintended pregnancies and even STDs. Sperm can live up to 5 days. I perform vasectomies on men, and I tell them to do a semen analysis 6 weeks later and after 20 ejaculations. Only then do I tell the overwhelming majority that they are sterile.

Question 4

how long does sperm from a previous ejaculation survive in the urethra ? if the previous ejaculation happened 5 days ago

Accepted Answer

All sperm gone : By now.

Question 5

how long does sperm live in the male urethra after ejaculation?

Accepted Answer

Probably about 1 hr: This is rough estmate &amp; can be shorter or longer. This is important with regards to safe sex if you have sex without condom some time after ejaculation. There may be live sperm in urethra &amp; means there is definite risk of unwanted insemination.

Question 6

is it true the first urine in the male is most likely to kill any remaining sperms in the urethra?

Accepted Answer

: Not true,

Mobile sperm is occasionally observed in the first voided urine in the morning.  
The sperm left in urethra remain alive up to 48 hours.

Question 7

how many hours after ejaculation does residual sperm last in the urethra and how motile is it say 20 hrs later?

Accepted Answer

Killed by urine: Sperm bathed in semen can live in urethra for many hours. However doubt that you lasted 20 hours without urinating. Thus residual semen containing sperm would have been flushed out or lysed (killed) by urine.

Question 8

i ejaculated 2 days ago and i have urinated each day since,whats the possibility that theres still sperm in my urethra & will there be in my precum?

Accepted Answer

Doubtful: get examined and make sure that you did not injure your urethra. Additionally, if you have had any unprotected intercourse, get screed for STDs.

Question 9

what if you recently ejaculated a few hours ago and urinated multiple times will there still be leftover sperm in the urethra and will mix with precum?

Accepted Answer

Yes: Precum can definitely contain sperm as well as STD's, whether from a previous ejaculation or from new production. You should wear a condom from the time the penis is erect enough to produce precum and through the entire act of intercourse through ejaculation. Remove the condom carefully and do not allow the fluid to come in contact with your partners genitals to prevent pregnancy or STD's.

Question 10

how long does sperm remain viable (able to impregnate) in the male urethra after ejaculation? most places say minutes to a few hours, but i found one place that said up to 72 hours. can an expert please help?

Accepted Answer

: The question should be how long sperm remain in urethra after ejaculation.  Sperms are normally washed out while urinating.   Sperms are occasionally found moving in urine specimen taken in early morning.
