Genital tract disorders
This prevents semen from being deposited at the back of the vagina during coitus (erectile impotence, absence of ejaculation).
It is worth mentioning the anomalous situation of the urinary meatus, whether below its normal location (hypospadias) or above it (epispadias), a penis with curvature that is a too pronounced or a big decrease in its size, and extreme obesity. Serious erection problems, premature or delayed ejaculation and other ejaculation problems (ejaculation towards the urinary bladder or lack of ejaculation) can also prevent the appropriate deposition of spermatozoa in the vagina.
