Effect of Alcohol on Testosterone

Hypogonadism (low testosterone) is common in chronic alcoholic men . Such hypogonadism has been shown to be due to alcohol toxicity occurring at the level of the testes as well as at the level of the hypothalamus and pituitary. Thus, in addition to reduced levels of plasma testosterone and a high prevalence of oligozoospermia. chronic alcoholic men frequently have concomitant “normal” or only minimally increased plasma levels of gonadotropins [follicle stimulating factor (FSH) and luteinizing hormone (LH)]

Studies Found
Low plasma testosterone values in men during hangover

Ethanol intoxication reduced testosterone and increased LH with no significant influence on estrogens, with more pronounced changes associated with hangovers

Acute Ethanol Administration Enhances Plasma Testosterone Levels Following Gonadotropin Stimulation In Men

Ethanol intake at 0.675g/kg was able to enhance the testosterone-increasing response to injected gonadotropin-releasing hormone in healthy men.

Acute Effect Of Alcohol On Androgens In Premenopausal Women

Testosterone was increased in healthy women at an oral dose of 0.5g/kg ethanol, and this increase was more prominent in women using oral contraceptives

Effect Of Acute Postexercise Ethanol Intoxication On The Neuroendocrine Response To Resistance Exercise

No significant influence on testosterone, adrenaline, or cortisol associated with alcohol intake after exercise

Effects Of Acute Alcohol Intake On Pituitary-gonadal Hormones In Normal Human Males

16 males consuming a large acute dose of vodka (2.2ml/kg 100-proof vodka within 15 minutes) noted suppression of testosterone after 84 minutes, with a spike in LH as well

Sex Hormones And Adrenocortical Steroids In Men Acutely Intoxicated With Ethanol

An increase in cortisol and decrease in testosterone was seen by 12 hours after a large dose of alcohol, and small trends that reached significance at 36 hours were seen for LH and FSH in being increased.

Intake of a moderate amount of alcohol (30-40g) over a period of 3 weeks is associated with slightly suppressed testosterone levels in men only.

The Effects Of Acute Alcohol Consumption On Recovery From A Simulated Rugby Match

1g/kg ethanol was unable to significantly influence the endocrine parameters measured, but was able to reduce power output the next day

Testosterone Increases In Men After A Low Dose Of Alcohol

Low dose alcohol (0.5g/kg) was associated with a small (17%) increase in testosterone, which was abolished when the metabolism of ethanol was reduced
