Evaluation of proteohormon concentrations in serum and seminal fluid and its relationship with sperm count.
The measurement of FSH, LH, and PRL in serum and seminal fluid of 105 men attending a male infertility clinic and 21 men of proven fertility (controls) did not reveal an interrelationship between the spermatozoal count and the level of the proteo-hormones in both biological fluid except for FSH, which was significantly higher in the serum of men with low as compared to normal sperm count (p less than 0.01). FSH in seminal fluid was significantly lower (p less than 0.01), and LH-like activity significantly higher (p less than 0.01) than in serum, while there was no difference between the respective levels of PRL. These results could be confirmed in 4 patients with azoospermia due to occlusive disease, and in 1 out of 2 vasectomized men. It was demonstrated for the first time that the higher concentration of "LH" in seminal fluid as compared to serum was due to the presence of HCG-beta or a HCG-like material cross-reacting with the antiserum against LH.
