SUBSTANCE: technique involves a blood serum examination for thyrotropic hormone, mcUnit/ml, free T4, pmole/l, prolactine, mIU/ml, follicle-stimulating hormone, mIU/ml, lutenizing hormone, mIU/ml, testosterone, nmole/l, dehydroepiandrosterone sulphate, mcg/ml, cortisol, nmole/l, oestradiol, pg/ml, 17-OH progesterone, nmole/l. Calculating an integral hormone state (HIS) by formula follows. If the HIS value is below 0.799, a habitual disorder is stated, which is accompanied by a minimum risk of the reproductive disorders. The HIS values falling from the range of 0.800 to 1.000 provides stating the tensed hormonal regulation reflecting a moderate risk of the reproductive disorders. The disturbed interhormonal cooperation corresponds to the HIS value falling within the range of 1.001 to ≤1.210 that represents a high risk of the reproductive disorders. The HIS value of more than 1.211 shows the lack of reserves that testifies to a very high risk of the reproductive disorders.
