AB One  or  both  testes  may  be  absent  from  the  scrotum  at  birth  in  about  20%  of  premature  or  low-birth-weight  male  infants  and  in  3–6%  of  full-term  infants.  Cryptorchidism  is  found  in  1–2%  of  males  after  1  year  of  age  but  must  be  distinguished  from  retractile  testes,  which  require  no  treatment.  Infertility  or  subfertility  occurs  in  up  to  75%  of  men  with  bilateral  cryptorchism  and  in  50%  of  men  with  unilateral  cryptorchism.  Some  patients  have  underlying  hypogonadism,  including  hypogonadotropic  hypogonadism.
