Will premature sperm die?

No, premature ejaculation will not “die”. It’s just regular sperm. Of course, its not as concentrated as the ejaculate itself, its mostly just the fluid the sprem travels in, but the few sperm that are emmitted live just like regular.

Are you worried about pregnancy using the “pull out” method?

Premature sperm never comes out of the male body I am happy (or sad depending on your reaction) to tell you. Sperm spends time in the testacles to make sure that it is mature enough to fertilize an egg. Mature sperm is stored in a seperate part of the testacle from the immature sperm. Hope I helped!

Sperm is matured to a certain degree in the male’s reproductive system (in the epidydimus) but does not reach full maturity until it reaches a favorable alkaline environment of the fallopian tubes of the woman. The sperm reaches capicitation (penetration of the ovum. The contractions of orgasm helps to move the more mobile sperm into the cervix which tips down during intercourse making it easier for the sperm to enter. The sperm that stay in the vagina (never making it to the cervix) die quickly in the acidic environment of the vagina.

If you are talking about the secretions of the sperm during foreplay if allowed to enter the vagina will go through either of the processes listed above. Basically, it all depends on the sperm. Good swimmers reach their goal and maturity.
