Yan' an Sunshine Hospital experts pointed out that the foreskin is too long, which is more common in men. It means that when men are adults, the penis skin is wrapped around the glans, so that the glans cannot be completely exposed. Among them, it can be divided into true redundant prepuce and false redundant prepuce. The true foreskin is too long, and the glans can't be completely exposed after penis erection. The false foreskin is too long, which means that the glans penis can not be completely exposed at ordinary times, but it can be completely exposed after erection. Whether the true foreskin or the false foreskin is too long, it is easy to breed scale, which brings trouble to the cleaning of male reproduction. Consult online experts because many men with too long foreskin do not pay attention to opening the foreskin frequently for cleaning due to lack of physical health knowledge, which is easy to cause long-term bacterial stimulation and glans inflammation. Moreover, repeated foreskin inflammation can easily lead to the adhesion between glans penis and foreskin, which will limit the erection of penis, and then cause pain in sexual intercourse, which will not only lead to disharmony in husband and wife's sexual life, but also lead to psychogenic sexual dysfunction. In addition, the reason why too long foreskin affects male fertility is that too long foreskin can easily lead to premature ejaculation in men. This is because men with long foreskin have sensitive nerves in their reproductive organs and can't stand any stimulation at all. When adults are slightly stimulated in sexual life, ejaculation will occur and premature ejaculation is prone to occur. Premature ejaculation caused by long foreskin not only affects the quality of sexual life, but also leads to impotence, which indirectly threatens male fertility.
