A normal sex life is a prerequisite for fertility, but a significant number of patients in male infertility clinics also suffer from sexual dysfunction, especially ejaculatory dysfunction. Ejaculatory dysfunction is generally divided into premature ejaculation, delayed ejaculation, non-ejaculation, retrograde ejaculation, and so on. The most common one is premature ejaculation. Patients often consult their doctors about their short sex life and ejaculation too fast, does it affect their fertility? What is the impact of ejaculatory dysfunction, including premature ejaculation, on fertility, and how should it be resolved? In terms of fertility, the function of ejaculation is to send sperm from the male body into the female body to make the union of sperm and egg possible. If ejaculation dysfunction prevents sperm from entering a woman’s body, it will undoubtedly have a greater impact on fertility and even lead to infertility; however, if ejaculation dysfunction does not prevent sperm from entering a woman’s body, it will generally not have much impact on fertility. The incidence of premature ejaculation is the most common disease in ejaculatory dysfunction, accounting for 35 to 50% of adult males, usually refers to men who lose the ability to control ejaculation during sex, before or just before penile insertion into the vagina that ejaculation. The vast majority of premature ejaculation patients ejaculate soon after penile penetration into the vagina, and only a very small number of patients ejaculate before penile penetration into the vagina. Therefore, for premature ejaculation patients, as long as they can ejaculate in the vagina, it will not affect their fertility. If you cannot ejaculate in the vagina, you must treat premature ejaculation. If you can ejaculate normally in the vagina after treatment, it is possible to conceive naturally; if you still cannot ejaculate in the vagina after treatment, you can undergo artificial insemination treatment to help you conceive. Patients with delayed ejaculation and non-ejaculation have difficulties in ejaculation, resulting in excessively prolonged sexual intercourse, making it difficult to achieve orgasm or even no orgasm. In general, patients with delayed ejaculation can eventually ejaculate in the vagina without affecting fertility; some patients are unable to ejaculate during normal sexual intercourse but can ejaculate through masturbation, and if their symptoms do not improve after appropriate treatment, they need to be treated with artificial insemination or in vitro fertilization. Patients who cannot ejaculate naturally but can ejaculate through electric massage can be considered for artificial insemination. Patients who cannot ejaculate through various treatments can have their testicles punctured to obtain sperm and then undergo IVF to help them conceive. Retrograde ejaculation refers to patients who ejaculate with orgasm during sexual intercourse, but the semen retrogrades into the bladder without ejaculating out of the urethra, mostly caused by organic lesions. Some patients with retrograde ejaculation can be treated surgically, but most patients do not receive effective treatment. Most patients need to be treated by collecting sperm in the urine after ejaculation and undergoing artificial insemination or IVF to help conceive.
