For couples who choose artificial insemination, not many of them are affected by male factors, while most of them are asthenozoospermia patients. Oligospermia and asthenozoospermia are just symptoms; after a clear diagnosis and etiology treatment, patients can become pregnant naturally. Many people think of artificial insemination and test tube baby as “omnipotent ". They can always work, which is a big mistake.

Artificial insemination uses and injects male semen into the female cervix or uterine cavity artificially to assist conception. This technology is mainly used in male infertility patients. Artificial insemination includes insemination between spouses and non-spouses.

For couples who choose artificial insemination, not many of them are affected by male factors, while most of them are asthenozoospermia patients. Oligospermia and asthenozoospermia are just symptoms; after a clear diagnosis and etiology treatment, patients can become pregnant naturally. Many people think of artificial insemination and test tube baby as “omnipotent ". They can always work, which is a big mistake.

◆How to perform full diagnosis for male or female infertility?

※Male semen analysis, dynamic digital vas deferens lipiodol angiography, six items for ECLI hormone tests, four-dimensional ultrasound, pituitary stimulation test, chromosome. (Requirements for examination: abstinence for two or three days)

※Vagina four-dimensional ultrasound, dynamic digital hysterosalpingography, six items for ECLI hormone tests, colposcopy, gynecological examination + leucorrhea routine, and electronic uterus laparoscopic inspection if necessary. (Requirements for examination: Non-menstrual period)

◆How long will the above male and female infertility test take? Antai could obtain the results and confirm the diagnosis at the same day.

◆Beijing Antai OBGYN hospital provide contracted treatment for male or female infertility patients, and if pregnancy was not reached within two years, full refund will be paid.

●About Oligospermia, asthenozoospermia, azoospermia and semen abnormalities:

※Oligospermia: In two continuous tests, if a sperm density of less than 20 million/ml was obtained, the patient can be diagnosed as Oligospermia.

※Asthenozoospermia: Refers to a, b grade of sperm inadequacy of less than 40%.

※Azoospermia: if no sperm was observed under the microscope, it can be called azoospermia. There are clinically two kinds of azoospermia; first: obstructive azoospermia; testicles can produce sperm and if vas deferens was blocked, it would resulted in azoospermia. Another Azoospermia characterized in testicle that dones not have spermatogenic cells, so it can not produce sperm, which is a kind of azoospermia indeed.

※necrospermia: no active sperm was found under microscope.

※Sperm non-liquefied and liquefied for longer time: it is not a disease! Non-liquefaction or longer liquefaction time of semen outside the vaginal environment is a protective mechanism. For these patients, the wives can normally get pregnant. After the causes for infertility was determined, copulation test (Antai unique inspection items) shall be carried out to conduct further examination.

※Low sperm motility: sperms could achieve a best dynamic activity between 32-37 degrees of temperature. If the temperature continues to decline, the activity will decrease. In some hospitals, patients were asked to go to the bathroom to take sperms; if it is in winter, the semen will be ejected in the cold container, and besides, if microscope was not equipped with heating device, a small amount of semen will be placed in cold glass slide which will resulted in the illusion of low activity under microscope.

Antai OBGYN hospital has a quiet, warm sperm extraction chamber and equipped with a 37 degrees constant temperature microscope station; low sperm motility (asthenozoospermia) detected in many other hospitals are normal in our hospital, which proved that most cases are caused by infertility of woman. The following are analysis on common causes of male infertility:

★Hypothalamic-pituitary factors leading to oligozoospermia, asthenozoospermia and azoospermia:

Hypothalamic secretes gonadotropin-releasing hormone (GnRH) to stimulate adenohypophysis to release follicle stimulating hormone (FSH) and luteinizing hormone (LH). LH was also known as interstitial cell stimulating hormone (ICSH), and can induce Leydig cells to produce testosterone. FSH acts in the seminiferous tubules and prompts sperm maturation. Gonadotropin secretion reduction; hypogonadism reduction; testosterone secretion reduction; spermatogenic obstruction; all these factors will ultimately lead to male infertility;

Antai Hospital applies gonadotropin treatment for male hypogonadism that happens secondary to gonadotropin secretion insufficient of hypothalamus – pituitary, which will help to restore spermatogenic function and promote the development of secondary sexual characteristics.

Available drugs include:

1. HCG could stimulate testicular interstitial cells to produce testosterone.

2. HMG could stimulate spermatogenic and androgen secretion. 2 to 3 times medication a week, lasting for at least 3 months.

★Varicocele factors leading to oligozoospermia, asthenozoospermia and azoospermia:

Expansion, bending and prolong of pampiniform plexus in spermatic cord are called varicocele, of which most occurs on the left. In males suffering from infertility, 39% are caused by varicocele. Its reason lies on degradation and atrophy of spermatogonia and decrease in the number of sperm, which is caused by either raised temperature in scrotal and reflection to the contra lateral, or regurgitation of serotonin or steroids secreted by left adrenal from left spermatic vein to testicle.

In hospital, varicocele is treated by high position ligation of spermatic vein with laparoscope and this method has following advantages compared with previous classic surgical methods:(1) structure of the blood vessels can be detected more clearly by the application of zoom lens, thereby spermatic vein and spermatic artery can be more easily identified, therefore, injury can be avoided. (2) Relapse rate could be reduced by a more completed surgical separation and offshoot ligation of spermatic vein. (3) For bilateral varicocele, laparoscopic surgery avoids a second incision and shortens the operation time. (4) In laparoscopic surgery, pulling testicles by hand could help passing the spermatic vessels and parallel veins through annulus accurately.(5)Improvement of semen quality after operation is better than that in traditional operation.

All patients could have diet immediately after anesthesia recovery, have same-day discharge and just need to take oral analgesics and anti-inflammatory drugs after operation. Patients should referral back to the hospital a week after surgery. For infertility patients, in order to access the response to operation, semen should be checked every three months, starting at the time of four weeks after the operation.

★Vas deferens epididymal lesions leading to oligozoospermia, asthenozoospermia, azoospermia

Epididymal obstruction can be congenital, inflammatory or primary disease. Azoospermia men have normal volume of semen, normal testicular size, palpable bilateral vas deferens, and enough spermatogenic capablity as shown in testicular biopsy; and the obstruction site is more likely to be in the epididymis. Before Vas Deferens epididymal anastomosis, Vas deferens angiographies need to be carried out to determine the patency of the vas deferens, and to determine the location and manner of the anastomosis according to the results of scrotal exploration. The most commonly used microsurgical method is vas deferens epididymal anastomosis. The majority of patients showed semen sperm within 3 months.

★About Cryptorchidism:

Cryptorchidism is an illness that characterize in unilateral or bilateral testicles remaining in the abdominal. During fetal period, the testicles are formed in the abdomen; usually, the testicles will drop into the scrotum near birth. About 3% of boys suffering from cryptorchidism at birth, but at about 1 year of age, most of their testicles will drop into the scrotum. If testicles were still not dropped, surgery shall be performed to place the testicle back inside the scrotum to prevent the risk of infertility or testicular torsion (testicular torsion pain in spermatic cord) and reduce testicular cancer. The surgery can decline the testicles into the scrotum and recover its normal function.
