No sperm worm! Whether the transportation is blocked or not is related
Dr. Wu Jianying stated that there are many reasons for male infertility, and Taiwan studies have shown that the top six most common causes are: unknown causes, varicocele, cryptorchidism, anti seminal antibodies, Crohn's syndrome (chromosome abnormality 47XXY), and sexual or ejaculatory dysfunction. The condition for diagnosis of azoospermia, which is a relatively serious condition in male infertility, is that no sperm is found in at least two semen tests, and the incidence is approximately 15% of all infertile males.
Azospermia can be broadly divided into two categories: "obstructive azoospermia" and "non obstructive azoospermia". "Obstructive azoospermia" refers to the absence of spermatozoa in the semen due to blockage of the sperm transport pathway, normal testicular size, normal spermatogenic function, and normal hormone testing. The treatment should be based on the reconstruction of the seminal tract as the first choice. If it is not suitable for the reconstruction of the seminal tract, sperm extraction should be considered. The success rate of sperm extraction is close to 100%.
"Non obstructive azoospermia" refers to abnormal testicular spermatogenesis, which is usually small in size, and most hormone tests are abnormal. Treatment can only be performed by testicular sperm extraction, with a success rate of about 50% to 60%.
Diversified Sperm Extraction Surgery for Vitality and Smart Selection
According to the location of sperm extraction, sperm extraction can be divided into vasectomy, accessory testicular sperm extraction, and testicular sperm extraction. Testicular sperm extraction can also be divided into percutaneous testicular sperm aspiration, traditional testicular sperm extraction, and microscopic testicular sperm extraction.
Percutaneous testicular sperm aspiration has a low success rate in sperm extraction and a small amount of sperm obtained, which is generally suitable for patients with good testicular conditions, such as obstructive azoospermia; Traditional testicular sperm extraction surgery involves making several incisions directly on the testicle, which can cause significant damage to testicular tissue and have a relatively high probability of testicular atrophy after surgery.
Dr. Wu Jianying said that microscopic testicular sperm extraction surgery uses a microscope to aid in enlarging the surgical field of vision. During the operation, it can clearly identify the direction of blood vessels and reduce damage to testicular tissue. The postoperative impact on testicular tissue structure and function is small, thereby improving the success rate of sperm extraction, but the disadvantage is that the operation takes a long time.
Pregnancy and childbirth should be evaluated before having sex for one year without pregnancy
Despite advances in medical technology, infertile couples who hope to conceive the next generation still need to grasp the timing of childbirth. Doctors remind that if a male or female partner has been having regular, non contraceptive sex for one year and still fails to conceive, men need to undergo an infertility assessment. However, if there are signs that a male may be infertile or have risk factors such as cryptorchidism, the timing of the assessment should be early, followed by appropriate diagnostic and therapeutic interventions to seek "vitality.".
