Hydrocele has not been associated as a direct cause of infertility nor does it usually drastically affect the male's reproductive capacity.
However, it is important to bear in mind that in cases of large hydroceles and stress, the blood supply and testicular tissue may be compromised. In addition, there may be cases where the hydrocele is associated with testicular infections, factors that directly influence fertility and the possibility of pregnancy.
Presenting hydrocele does not represent any danger to the individual who suffers it, or to his testicles. However, this condition may be associated with testicular tumours and infections, inguinal hernias and testicular torsion, for this reason, a review with the medical specialist is necessary to evaluate the conditions of the disease and its association with other pathologies.
Emergency medical care should also be sought in cases where the scrotum suddenly increases in size, becomes tight and begins to be very painful.
During the intrauterine development of men, the testicles descend through the peritoneal vaginal canal from the abdomen into the scrotum. This process is surrounded by a sac called tunica vaginalis, which has fluid inside it; normally this membrane closes before birth and the fluid is reabsorbed. In many cases, the tunic closes but the liquid is not reabsorbed forming a non-communicating hydrocele. In other cases, the tunic does not close and the liquid can pass freely from the abdominal cavity into the scrotum, forming a communicating hydrocele and with the possibility of an inguinal hernia.
