WATCHFUL WAITING TO 6 MONTHS, THEN SURGICAL REFERRAL (NO DRUG THERAPY)
Undescended testis - disease-level clinical article (undescended-testis-full.txt)
The whole management is a clock. If the testis has not come down by 6 months, the article treats spontaneous descent as unlikely, and turns to surgery: the AUA guidelines it cites advise operating on a congenitally undescended testis somewhere between 6 and 18 months of age. Nothing is prescribed; a date is set.
- THE WINDOW - where the testis stays undescended, the advice is orchidopexy somewhere between 6 and 18 months of age, bringing it down into the scrotum, which lowers the risks and gives infertility less chance of following. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
- EARLIER IS BETTER WITHIN THAT WINDOW - many specialists favour operating early, often at around 6 months, to give the testis the best growth and to protect fertility. The younger the child, moreover, the shorter the distance the testis has to travel; that distance grows as he does. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
- BEFORE 6 MONTHS, WAIT - left alone, an undescended testis will most likely come down within the first 3 months of life (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270), and descent of its own accord remains possible through the first 6 months. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
- NO HORMONE IS PRESCRIBED HERE, AND THAT IS THE ARTICLE'S POSITION - the AUA guidelines advise against using hormones to bring a testis down: too few respond, and nothing lasts. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270) A meta-analysis of 7 randomised trials, the article adds, found hormonal treatment no better than placebo. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270) hCG is reserved for a named exception (Prader-Willi syndrome) and is a specialist decision.
- DO NOT ORDER AN ULTRASOUND - scanning as a matter of routine gets you nowhere: at finding a testis that cannot be felt it runs at 45% sensitivity and 78% specificity. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270) Worse: of the boys with an impalpable testis and a scan that showed nothing, 49% turn out in the end to have one inside the abdomen. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270) A normal scan delays surgery and proves nothing.
- As things stand, no radiological test can establish beyond doubt that a testis is absent. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
- EXAMINE, DO NOT IMAGE - an experienced pair of hands can feel over 70% of undescended testes, and those need no imaging at all. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
- MOST BOYS DO NOT NEED THIS AT ALL - 3% of babies born at term have an undescended testis, and the figure falls to 1% between 6 months and 1 year of age. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270) Among boys born prematurely it is 30%. (Cryptorchidism - StatPearls - NCBI Bookshelf, NBK470270)
