How long can seeds survive
How long do sperm survive?
Anyone who underestimates the lifespan of sperm may be surprised by an unplanned pregnancy. How long does sperm survive depend on?
The lifespan of sperm depends mainly on two factors:
- The sperm quality
- The woman's cycle phase
The question "How long do sperm cells actually survive?" Some women only pose themselves when they are amazed at the pregnancy test. Anyone who did not have sex at the time of ovulation and afterwards and still becomes pregnant has probably not considered the lifespan of sperm. Ironically, the days immediately before ovulation are often the days when conception works. This is because sperm can still be able to fertilize a mature egg for up to five days after sex.
The sperm quality affects their survivability
It takes ten weeks for sperm to be ready for use. First, they mature in the testicles, from there to migrate to the epididymis and continue to mature. Here the sperm can remain viable for up to a month. Either they are excreted with an ejaculation during this time and possibly fertilize a female egg, or they die if an ejaculation does not occur. Then the next generation of sperm matures.
How well a man's sperm are in shape can vary greatly, because lifestyle and diet, but also factors such as medication intake, have a major influence on sperm quality. The healthier the sperm, the longer they can survive after sex. A man can use a spermiogram to examine how the quality of sperm is in general.
Which phase of the woman's cycle lets sperm live the longest?
The ideal pH value at which sperm feel particularly comfortable is 7.5. However, the mucus on the cervix changes its pH value - it is particularly sperm-friendly right at the beginning of the fertile days. Nature has cleverly arranged this to turn all traffic lights in the direction of procreation to green.
Since the vaginal environment is now less acidic, the sperm can hold out for up to five days in order to hopefully come into play at the right moment and meet a fertilized egg cell. Less acidic doesn't just mean less harmful. The more alkaline environment of the cervical mucus attracts the sperm magically, even magnetically, so that they can dash to their destination even better.
Couples who want a baby and are willing to have sex according to their schedule should therefore definitely plan the days before the expected ovulation. Great things can happen here! But if you, on the other hand, want to prevent pregnancy and do not rely on permanent solutions such as the pill or the IUD, you should not only use a condom on the fertile days, for example, but also a few days earlier.
