Effect of microwave contraception on human serum testosterone and luteinizing hormone
Abstract
Using home-made match kits and radioimmunoassay, both serum luteinizing hormone (LH) and testosterone (T) were measured in 53 healthy adult males using microwave contraception and 76 normal fertility males as control. The results showed that in contraceptive group the serum T level was significantly decreased (p 0.0001), while serum LH was apparently elevated (p 0.01) as compared whith the normal controls. Furthermore, the longer exposure duration the lower serum T declined and the higher serum LH increased (p 0.001). The present study suggests that the microwave dose used for contraception seems to cause damage in Leydig cell function in terms of T production, and then influence endocrine function of testis. The progressively increased LH level also indicates certain degree damage of the Leydig cells. However, the damage might be reversible. The results may be useful for further clinical investigation.
