Patient: The baby is now two months old and has been diagnosed by the local doctor as possibly having bilateral cryptorchidism, I would like to know how to confirm the diagnosis? How to treat it? I read on the internet that hcg injection is needed, I wonder how many months to start treatment? Expert: The diagnosis of cryptorchidism mainly relies on the doctor’s physical examination, and individual cryptorchidism that cannot be palpated needs ultrasound or even laparoscopy for supplementary diagnosis. The diagnosis of bilateral cryptorchidism requires surgery, and the timing of surgery is appropriate around 1 year old and must be completed before 2 years old. HCG (including other medications such as LHRH) may be helpful for a low positioned testicle, but from my personal experience, it is difficult for medications to restore the testicle to its normal position unless it is very low. Therefore, I personally only recommend HCG in very rare cases.
