ABSTRACT
Androgens such as mesterolone, which do not aromatize, have the same effect as testosterone and its esters on serum cholesterol (24,26).
Testosterone administration does not promote fertility. Although low doses of testosterone undecanoate combined with tamoxifen citrate have been suggested to serve as a treatment of oligospermia, this treatment cannot be considered as evidence based (27). If men with secondary hypogonadism want to have children, pulsatile GnRH or recombinant FSH and recombinant LH treatment can stimulate spermatogenesis. Men with primary hypogonadism wishing to have children should be referred for assisted reproduction technology (for more details see chapters 11, 27, and 28).
