The Chinese traditionally attach great importance to the issue of having children so as to “start a family”, although many young couples aspire to a “Dinky” family where they can enjoy the spontaneity of a two-person world. Although many young couples aspire to a “Dinky” family where they can enjoy the freedom of a two-person world, a family without children is never complete. Infertility is often an unspeakable problem for couples who desire to become parents. Infertility is a condition in which a couple has lived together for more than a year after marriage, has a normal sexual life, and does not use any contraception, but the woman fails to conceive. The infertility caused by the male side is called male infertility, accounting for 30-40% of infertility. Medical studies have shown that the incidence of male infertility has increased significantly with social development, and in large cities with high industrialization and dense population the incidence can reach about 10%. Male infertility is not an independent disease, but the result of one or more diseases/factors, whose causes include neuroendocrine factors, testicular and post-testicular factors and infections and sexual dysfunction, as well as daily bad habits (such as tobacco and alcohol addiction), environmental pollution and the patient’s own disease (such as ejaculation, the patient can not ejaculate and make sexual intercourse too long, resulting in difficulty in reaching orgasm) can lead to male infertility. ) can all lead to male infertility. According to its clinical manifestations, male infertility is divided into absolute infertility (complete lack of fertility, such as azoospermia) and relative infertility (some fertility, but fertility is below the threshold required for pregnancy, such as oligozoospermia). Male infertility is caused by a variety of complex factors, so it is especially important to go to a regular hospital for a systematic examination to clarify the cause. Many patients are in a hurry to seek medical help, one-sidedly interpreting male infertility as “sexual incompetence” and indiscriminately taking supplements; or blindly listening to the treatment experience of other patients without distinguishing the cause of the disease. According to Professor Liu, there are many treatments for male infertility, such as medication, surgery or artificial assisted reproduction, and different methods or medications must target specific causes to achieve results. In the diagnosis of male infertility, the patient’s semen examination is the most important, and the results of semen analysis can provide an objective assessment of the patient’s fertility. For infertility caused by non-ejaculation or when artificially assisted reproduction is used to treat infertility, ejaculation needs to be induced, and the help of equipment such as an electronic ejaculator is needed in this case. The electronic ejaculator helps ejaculation in a wide range of applications, mainly for patients with insemination, such as those with recalcitrant insemination (those for whom conventional treatment is ineffective), those with high paraplegia, those who are unable to ejaculate after retroperitoneal lymph node dissection; those with cancer before marriage who need to preserve semen; those with diabetes secondary to insemination and those with brain death who have a need for artificial insemination, all can ejaculate smoothly with the help of the electronic ejaculator. This is incomparable to other methods of sperm retrieval. The principle of the electronic ejaculator is that the rectal probe (with special electrodes on the surface) is inserted into the rectal mucosa from the anus to the back of the seminal vesicles and prostate gland. Through intermittent and increasing electrical stimulation, it causes excitement contraction of the seminal vesicles, vas deferens, ejaculatory ducts, prostate and urethra and other related tissues, and stimulates the patient’s ejaculatory nerve, causing the patient’s penis to gradually become erect and finally ejaculate, thus achieving the purpose of accurate sperm collection. Patients may have unbearable pain during electrical stimulation of ejaculation, so hospitalization with general anesthesia or continuous epidural anesthesia or lumbar anesthesia is required. Complications are rare, and there may be occasional blood in the stool due to damage to the rectal wall. The preferred method of fertility for patients with intractable ejaculation is to apply electrical stimulation to obtain semen for assisted reproduction. After semen collection, the semen is sent to a human sperm bank for freezing and storage, and waiting for the arrival of female ovulation to produce pregnancy using AIH (artificial insemination of husband’s semen) or ICSI (intracytoplasmic single sperm injection). According to Prof. Liu, Tongji Hospital is the first in Hubei Province to introduce electronic ejaculation instrument to extract sperm for patients, and has been carrying out this work for nearly a year, treating more than 10 cases of recalcitrant non-ejaculation, all receiving good results.
