Backgraund: There is insufficient data on the duration of recovery of HPG axis after abuse of androgenic anabolic steroids (AAS).
Aims: to evaluate the recovery of HPG axis in men, AAS users, after a 3-month of cessation of their use and after PCT.
Materials and methods: An observational, single-center, prospective, sampling, open, uncontrolled study was conducted among male AAS users. While using of AAS and 3 months after the refusal of their administration and PCT, the clinical symptoms of hypogonadism were evaluated, luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (Tt), prolactin, estradiol, inhibin B, thyroid-stimulating hormone (TSH) were determined. The scheme of rehabilitation therapy was the same and did not change throughout the study. Recovery criteria: Tt3.4 ng/ml and LH1.24 mIU/ml. The study was conducted from January to August 2019. Fisher's exact test, Mann-Whitney U-test, and Spearman's rank correlation coefficient were used. The differences were considered statistically significant at p 0.05.
Results: The study included 44 men, their age 29 years [27.75;34], the duration of the use of AAS is 6 months [3.52;7]. During the use of AAS: LH 0.2 mIU/ml [0.04;0.47], Tt - 4.34 ng/ml [1.05;8.81]. In this group, the number of men with a LH level1.24mIU/ml was 84% (n=37) and Tt3.4ng/ml was 47.7%(n=21). After 3 months, the LH level reached 4.12 mIU/ml [2.58;5.84], Tt - 4.55 ng/ml [3.76;6.24]. At the same time, the level of Tt3.4 ng/ml remained in 20.5% (n=9); LH1.24 mIU/ml in 4.5%(n=2) men. According to the level of recovery of LH and Tt, patients were divided into two groups: with satisfying (n=35;79.5%) and poor (n=9;20.5%) recovery. A clear correlation was established between the duration of use (-0.857; p0.0001), the amount (-0.443; p=0.003), the dose (-0.7825; p0.0001), the type of AAS (-0.698; p0.0001).
Conclusions: A three-month refusal to use AAS with PCT led to the restoration of HPG axis a in 79.5% of the volunteers. The negative effect of the duration of use, the number of simultaneously administered drugs, their dose and type of AAS on the restoration of HPG axis was established.
