Quitting Anabolic Steroids Can Still Impair Men Afterward

BOSTON — Men who stop using performance-enhancing anabolic-androgenic steroids (AAS) experience significant depression, anxiety, and diminished sexual function within the first year after quitting, new research found.

The data suggest that monitoring these men and, pending clinical trial evidence, intervening to minimize these effects could help prevent recidivism, Bonnie Grant, MBBS, a clinical research fellow at Imperial College London, London, England, told Medscape Medical News.

“Nothing has actually been studied in proper randomized controlled trials…but I think there’s going to be a role for medicine alongside psychological treatment…Clinicians often see men who have stopped [taking steroids] who report feeling low in mood…a lot of these men will just restart taking them again,” she said.

Anabolic steroids taken exogenously suppress the hypothalamic-pituitary-gonadal system, thereby suppressing endogenous testosterone secretion. While AAS do enhance muscle-building, they can also lead to enlarged hearts, hypertension, and infertility. Most of these are reversible if the man stops taking the AAS.

However, after stopping, the testosterone levels can take up to a year to return to normal. During that time, the man can experience symptoms including low libido, erectile dysfunction, low mood, and fatigue. This leads to a dependence syndrome in about 30%. About 65% of men who stop taking anabolic steroids will restart taking them within the first year, Grant said in presenting her findings at the ENDO 2024: The Endocrine Society Annual Meeting.

Asked to comment, session moderator Frances Hayes, MBBCh, associate clinical chief of the Division of Reproductive Endocrinology at Massachusetts General Hospital, Boston, said, “One question is, if you intervene with an antidepressant, will that prevent the people from relapsing and going back to using? I think that’s certainly something that would need to be explored and tested.”

Hayes also noted that fertility problems may lead some men to decide to stop using the steroids. “That can be a strong motivator. If you have a motivated patient, then you add in an antidepressant or anxiolytic or link the patients with mental health services. I think that would definitely be beneficial and definitely something we need to address and see if it is worthwhile doing.”

Grant presented data from her group’s cross-sectional, observational study. Of a total 245 men, 116 were current AAS users, 84 were previous AAS users who had quit within the past year, and 45 had never used them. All completed extensive questionnaires about their substance use, mood, sexual function, and anxiety. They had morning blood tests, and urine samples were taken for toxicology testing.

The three groups didn’t differ by age (most were in their mid-30s) or ethnicity (most were White). However, the proportion who self-reported psychiatric diagnoses (mostly depression or anxiety) was significantly higher among both the current (29%) and past (25%) AAS users than among the never users (6.6%), with P = .0094.

Hayes commented, “One of the drawbacks of this study was they didn’t have baseline data. But it would make sense, I think, that the incidence of depression and anxiety was higher in the people who went on to use anabolic steroids.”

Use of other illicit drugs — mostly cocaine and cannabis — was also higher among the past (40.5%) and current (47.4%) AAS users than among the nonusers (17.7%), P = .0025.

Not surprisingly, total testosterone levels were much higher in current AAS users (62.8 nmol/L) than in past users (20.1 nmol/L) and nonusers (20.0 nmol/L), P luteinizing hormone (LH), follicle-stimulating hormone, and sex hormone-binding globulin were significantly lower in the current AAS users than in the other two groups, while estradiol levels were significantly higher (all P

There were no differences in total testosterone between the never users and previous users. However, about 25% of the men who stopped continued to have lower-than-normal testosterone levels, Grant noted.

Depression scores, as assessed by the Beck Depression Inventory-II, were highest in men who stopped using AAS, and lowest in the never users. Moderate to severe depression was present in 20% of the men who stopped using AAS, 6% of current users, and none of the nonusers.

In multivariable analysis, having a prior psychiatric diagnosis increased the risk for current depression on the Beck inventory by twofold in the current AAS users (P = .001) and threefold in the past users (P

Sexual function, as measured by the International Index of Erectile Function (IIEF) 15, was significantly worse among those who had stopped using AAS compared with current users and nonusers (P = .023). At the same time, total testosterone levels were only weakly correlated with IIEF scores.

In multivariate analysis, higher LH levels were associated with worse sexual function (P = .01).

Anxiety, as measured by the General Anxiety Disorder-7 assessment, was higher in previous users than in never users. Overall, 12% of the previous users had moderate or severe anxiety vs just 2% of nonusers.

The next step in the research will be to examine the urine toxicology for AAS and other illicit substances, Grant said.

“We’re hoping this information will allow for future studies to be developed to design treatments, which will help millions of men worldwide to stop and stay off anabolic steroids,” she concluded.

Grant and Hayes had no disclosures.
