The problem of blocked fallopian tubes has always been a highly hated reproductive system disease among many female friends, leading to a series of serious problems such as female infertility. But male vas deferens can also have problems, and even some male friends are born without a vas deferens! This is called absence of the vas deferens, so can this absence of the vas deferens lead to normal pregnancy? Can the absence of the vas deferens really be cured?

1、 Causes of absence of vas deferens

Congenital absence of the vas deferens, as a congenital malformation of the male reproductive system, has always been suspected to be related to genetic factors. For example, it has been found that the disease accumulates in some families, and in clinical practice, cystic fibrosis is closely related to congenital absence of the vas deferens, providing strong evidence for the important role of genetic factors. Since the late 1980s, significant progress has been made in clinical and molecular genetic research on cystic fibrosis, with molecular level research on the relationship between the disease and congenital absence of the vas deferens achieving congenital progress, mainly due to embryonic development. The development of the mesonephric duct stops being blocked or degenerated, resulting in the loss of the vas deferens. For the absence of one vas deferens, it often does not affect male reproductive function and generally does not require treatment. If both vas deferens are missing, it often leads to male infertility. Assisted reproductive technology is usually needed to assist patients in childbirth.

2、 Is it possible to conceive normally if the vas deferens are absent?

Absence of the vas deferens is a congenital malformation that develops not far from one or both renal ducts during the embryonic stage, resulting in a defect of the vas deferens. Divided into unilateral and bilateral absence of the vas deferens, it is an important cause of obstructive azoospermia and male infertility. The absence of the vas deferens can lead to inheritance of male reproductive organs and cannot lead to normal pregnancy. Only assisted reproductive technology can help patients achieve reproductive needs. If the testicles develop normally, artificial insemination or in vitro fertilization can be performed by puncturing and extracting sperm. When going to the hospital for examination, it is necessary to adopt reasonable treatment methods based on specific reasons and actively cooperate with the doctor's treatment. Patients may not have symptoms in their daily lives, mostly due to years of infertility after marriage.

3、 Can the absence of the vas deferens be cured?

Bilateral absence of vas deferens is related to congenital development. In this situation, a cure is unlikely. If testicular puncture is performed and there are mature sperm and healthy sperm in the testicles, pregnancy can be achieved through in vitro fertilization or artificial insemination. The patient is physically healthy, has normal sexual activity, can ejaculate, and cannot reach the vas deferens through palpation of the scrotum, resulting in unilateral absence of the vas deferens. Because the opposite testicular vas deferens are normal and do not affect normal fertility, treatment is not necessary. Repetitive vas deferens malformation has no clinical symptoms, normal sexual activity, and is more common in scrotal exploration.

Overall, as a common genetic defect in the male reproductive system, absence of the vas deferens cannot be treated through surgery, let alone medication, as there is no vas deferens at all. But this does not mean that patients cannot reproduce. Current in vitro fertilization techniques can successfully perform fertilization in vitro as long as the male partner has viable sperm. The absence of the vas deferens often results in intact testicles and does not result in the absence of sperm!
