Final answer:
Hypospadias is the congenital condition of the male urethra where the opening is on the underside. The urethra serves both urinary and reproductive functions in males. Spermatogenesis occurs in the seminiferous tubules in the testes.
Step-by-step explanation:
The congenital condition of the male urethra referred to in the question is hypospadias. This is a condition where the opening of the urethra is not located at the tip of the but on the underside. The other options provided, such as varicocele, relate to other conditions: varicocele is an enlargement of the veins within the scrotum, phimosis is a condition where the foreskin cannot be retracted over the glans, circumcision is a surgical procedure to remove the foreskin, and hydrocele is the accumulation of fluid in the scrotum.
The urethra is part of the male urogenital tract that is shared by both the urinary and reproductive systems. The prostate gland, seminal vesicles, and vas deferens play roles in the reproductive system but are not shared with the urinary system.
Within the male reproductive system, sperm are produced in the seminiferous tubules of the testes. The vas deferens transports sperm from the testes, and during ejaculation, sperm are mixed with seminal fluids produced by the prostate gland and the bulbourethral glands, which contribute to the semen.
