Background:
In otherwise normal boys with undescended testes, early orchidopexy is recommended to preserve fertility, to decrease the risk of testicular cancer, and to facilitate its detection. Indeed, compared to the general population, the risk of testicular cancer is increased two- to eight-fold in isolated cryptorchidism and usually occurs before the age of 40 years. By contrast, when cryptorchidism is associated with congenital hypogonadotropic hypogonadism, the risk of testicular cancer is unknown.
Objective:
The aim of this study was to determine the characteristics of testicular cancer when cryptorchidism is associated with congenital hypogonadotropic hypogonadism.
Methods:
We conducted a PubMed research without date limits including the following key words: hypogonadism, hypogonadotropic hypogonadism, testicular cancer, testicular germ cell tumors, undescended testis, Kallmann syndrome, FSH, AFP (α foeto protein), βHCG.
Results:
Only 3 patients with testicular cancer and congenital hypogonadotropic hypogonadism have been published in the past 4 decades and two were diagnosed at 50 and 64 years.
Conclusion:
Gonadotropin deficiency may protect against testicular cancer, and orchidopexy in this context may be deferred.

01:30Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
