The failure of one or both of the testes to fail to descend into the scrotum is known as ‘cryptorchidism’.
In the unborn child the testes lie close to the kidneys. During approximately the 7th month the testes start to descend through the inguinal canal and into the scrotum. Occasionally, an improperly developed testis may be halted in its descent in the abdomen and may not produce the hormones that induce secondary sex characteristics.
A testis lodged in the inguinal canal may well produce these secondary sex characteristics but may not produce spermatozoa. Usually, only one testis is involved and the other produces sufficient numbers of spermatozoa.
To have both testes fail to descend is unusual.
According to information I have read, undescended testis can be brought down into the scrotum by medical treatment with the gonadotrophic hormone and that this is the preferred treatment to surgery.
I am not very informed on this particular problem so it might be an idea to ask your GP some more searching questions, as to this possibility.
I have also read that it is possible to use hormonal herbs to achieve the same result. I have not had experience trying this either and the only herbs I have seen mentioned were a Chinese blend available over the internet but with no particular ingredients mentioned.
Most herbs used for ‘male’ problems are generally tonifying and I do not know if they would actually activate the gonadotrophic hormone.
