Most cases of renal agenesis are not inherited from the parents, nor do they result from any behavior by the mother. Some cases, however, are caused by genetic mutations. These mutations are passed on from parents who either have the disorder or are carriers of the mutated gene.

Is renal agenesis fatal?
Unilateral renal agenesis means that a baby develops only one kidney. Found in roughly one in 1,000 live births (higher in twins), this condition is not fatal and often causes no additional symptoms. When a baby has just one kidney, the organ grows larger to compensate and perform the functions of both.
How long can you live on 1 kidney?
This usually takes 25 years or more to happen. There may also be a chance of having high blood pressure later in life. However, the loss in kidney function is usually very mild, and life span is normal. Most people with one kidney live healthy, normal lives with few problems.
Which part of the male body produces sperm?
The testes
The testes are where sperm are produced. The testes are linked to the rest of the male reproductive organs by the vas deferens, which extends over the base of the pelvic bone or ilium, and wraps around to the ampulla, seminal vesicle, and prostate. The urethra then runs from the bladder through the penis.
What is seminal colliculus?
The verumontanum or seminal colliculus is the rounded eminence of the urethral crest within the posterior wall of the mid prostatic urethra. The prostatic utricle opens into it in the midline and the two ejaculatory ducts open just distal to the utricle.
Can sperm get clogged up?
Sometimes the tubes through which sperm travel can be blocked. Repeated infections, surgery (such as vasectomy), swelling or developmental defects can cause blockage. Any part of the male reproductive tract can be blocked. With a blockage, sperm from the testicles can’t leave the body during ejaculation.
