What Happens to Sperm Count after a Vasectomy?

Vasectomy adhesion is the main cause of male infertility. His occurrence will prevent the sperm from smoothly exiting the vas deferens, leading to the occurrence of azoospermia.

Vascular adhesions are causing

Epididymis or vas deferens palpation abnormal; blood FSH levels are basically normal or slightly elevated. There is no sperm or low sperm count in the semen; the testicles are normal or slightly reduced in size, and the quality is basically normal; some of them have epididymis or vas deferens palpation that can be normal.

Congenital anomalies. The vas deferens are congenitally undeveloped or stunted, and are not connected to the epididymis. They are often accompanied by non-development of the seminal vesicles, resulting in a small amount of semen and no sperm.

Inflammatory stenosis. Various pathogens cause inflammation of the vas deferens, form scars, and cause occlusion of the lumen. Severe cases cause azoospermia.

tumor: from the vas deferens itself or adjacent organs caused by tumor compression caused by tumor lumen, is also one of the causes of azoospermia.

Traumatic or surgical injury, such as hernia repair caused by lumen obstruction. Vasectomy is one of the main methods of male sterilization, which is to artificially block the lumen and prevent sperm from being discharged to achieve birth control.

1. Routine check of semen : check whether there is sperm in men's semen, or whether the number of sperm is small.

2. Vasectomy: Vasectomy is performed by injecting a contrast agent into the vas deferens by incision or percutaneous puncture, so that it shows the tissue structure of the vas deferens, seminal vesicles, and ejaculatory ducts to understand whether the vas deferens are unobstructed and whether the seminal vesicles have pathological changes Etc., the cause of male infertility is clearly identified.

3. Surgical exploration: Surgical exploration in the scrotum is clinically the ultimate method for diagnosing obstruction of the insemination duct, because some lesions cannot be found by physical examination or angiography. Experts suggest that scrotal surgery can be performed at the same time as epididymal biopsy to avoid secondary surgery.

Vas deferens epididymal anastomosis

Vasectomy and epididymal anastomosis is the current "gold standard" for the treatment of epididymal obstruction. It reduces the chance of anastomotic leakage, makes the recanalization rate as high as 91.7%, reduces surgical complications, and sperm appear in the semen 3 months after surgery.

Three types of vas deferens epididymal anastomosis

1. End-to-end anastomosis of the vas deferens epididymis:

The epididymal tubule was anastomosed with the vas deferens. Due to the large disparity between the vas deferens and epididymal lumen, and the dilated epididymal canal wall is very thin, it is difficult to operate practically. Another improved type of end-to-end anastomosis is to drag a section of the epididymal canal into the vas deferens and The head is fixed in the vas deferens, and the adventitia of the vas deferens and the epididymis are sutured.

2. End-to-side anastomosis of the epididymal vas deferens:

The entire epididymal cross section is used to anastomosis the vas deferens. First, sperm should be found in the exudate of the epididymis cross-section, and then the vas deferens are cut laterally for anastomosis.

3. End-to-side anastomosis of the vas deferens and epididymis ducts:

In this method, a segment of the epididymal tube with sperm confirmed by puncture is selected, which is opened at the side and coincides with the distal end of the vas deferens. The endometrium of the vas deferens and the entire epididymal duct were intermittently sutured. The adventitia of the vas deferens and the epididymis are embedded and sutured. Another type of telescopic end-to-side anastomosis is to drag a section of epididymal tube with a side incision into the vas deferens and fix it. The vas deferens and epididymis are embedded and sutured.

Vasectomy

Vascular anastomosis includes conventional vasectomy and microvasal anastomosis. The conventional anastomosis method is simple and easy to master, but the surgical success rate is low. Microscopic anastomosis can align the layers of the vas deferens neatly, and the success rate of surgical treatment of vas deferens is significantly higher than that of conventional vas deferens.

Surgical indication

1. The child who died after the vas deferens was blocked and required to give birth again.

2. After the vas deferens are blocked, the spouse dies or divorces and remarries.

3. Patients with epidural stagnation after non-surgical treatment of vas deferens after non-healing.

4. Severe sexual dysfunction occurs after vas deferens blockage, and those who fail to treat for a long time are ineffective.

Vas deferens epididymal anastomosis

It is currently the preferred method of treating obstructive azoospermia in medicine. The operation is quite difficult. It requires doctors to have superb microsurgery technology and rich clinical experience. The operation requires a lumen with a diameter of only 0.3-0.4mm. Establishing a relatively good, unobstructed, and leak-proof anastomosis is the key to guaranteeing recanalization and pregnancy rates.

Three Characteristics of Vascular Vascular Microlayer Anastomosis:

Feature one: Good surgical anastomosis and high success rate!

The technique of microsequestration vas deferens anastomosis precisely positions sutures according to the diameter of the anastomosis tube before anastomosis, so you can focus on the anastomosis operation without considering the position of the sutures during anastomosis. Good anastomosis results can be obtained even when the cavity diameters do not match. In addition, the full-layer anastomosis suture is difficult to break the vas deferens mucosa, and the knots are not left between the anastomotic muscle layers. The 6-layer full-suture suture is fully aligned and healed well. The pregnancy rate reached 64%, greatly improving the phenomenon of previous surgical failures.

Feature 2: Short operation time, safe and reliable!

Vascular microscopy full-layer anastomosis shortens the traditional operation time, greatly reduces the patient's pain during the operation, and uses micro-technology throughout, which is safer and more reliable!

Feature three: fast recovery, no complications!

Because the vasectomy full-thickness anastomosis makes the surgical wound small and easy to recover; the incidence of postoperative sperm cysts is also greatly reduced compared to traditional non-nested end-to-side anastomosis methods, so that there is no complications!
