With coitus interrupted, is it safe that I will not get pregnant?
Even with interrupted coitus it is possible to get pregnant since the pre-ejaculatory fluid, emitted from the penis before orgasm, can also contain a sufficient amount of sperm to fertilize the female egg; furthermore, it is good to remember that this practice does not protect against sexually transmitted infections.
Even today many couples are convinced that stopping penetration just before ejaculation is an effective method to avoid pregnancy: this belief has no scientific basis.
In these cases the risk of pregnancy is linked to the presence of spermatozoa in the secretions that precede ejaculation during sexual intercourse. This small quantity of spermatozoa is able to fertilize an oocyte.
The World Health Organization (WHO) has estimated that the percentage of women who have had an unwanted pregnancy using the interrupted coitus method during the first year of use varies from 4 to 27% depending on the attention paid to the practice it.
Furthermore, this type of contraceptive practice does not prevent the transmission of bacteria and viruses by sexual way that are contained in the vaginal and pre-ejaculatory fluid.
It is therefore advisable to always protect sexual intercourse by using condoms or other effective contraceptives rather than relying on interrupted coitus.
