Premature ejaculation in men can lead to normal fertility and does not affect sperm production or transport, and does not affect the quality of semen, which can still combine with the egg to form a fertilized egg. Premature ejaculation in men is only a short ejaculation time or a short latent ejaculation time, which makes both partners not reach a state of full psychological satisfaction. This condition is not an organic lesion that affects the quality of semen, and it does not affect fertilization of the egg, nor does it affect the union of sperm with the egg, so normal fertility can take place. For patients with severe premature ejaculation, the male has not yet entered the female vagina to ejaculate, and no sperm-egg union will occur at this time. The majority of patients with premature ejaculation are able to maintain intercourse for about 1 minute, at which time they can ensure that the ejaculated semen enters the woman’s vagina and further unites with the egg to produce a fertilized egg, so they can have normal fertility.
