Alpha-Pregnanediol in men's urine is a metabolite of progesterone, a hormone present in males but at lower levels compared to premenopausal women. Progesterone is primarily produced in the corpus luteum following ovulation in women and to a lesser extent in the adrenal glands of both sexes. In men, it plays a role in the production of testosterone and sperm development.
In the male body, progesterone undergoes metabolic pathways, leading to the production of two isomers of Alpha-Pregnanediol, namely 5α-pregnanediol (5A-PD) and 5β-pregnanediol (5B-PD). Among these isomers, 5B-PD represents the majority endpoint of endogenous progesterone metabolism and is considered to have little physiological activity. On the other hand, 5A-PD, the lesser metabolite of progesterone, can cross the blood-brain barrier and partially agonize GABA-A receptors. This action is likely due to its role as a precursor to allopregnanolone, a potent neuroactive steroid capable of binding the GABA-A receptor, leading to calming, sedative, and anxiolytic effects.
Since Alpha-Pregnanediol levels are related to progesterone metabolism, they can be a valuable marker in monitoring hormone therapy, including supplementation of oral progesterone or pregnenolone. It's essential to consider these levels alongside other androgen and progesterone markers to gain a comprehensive understanding of the individual's hormonal status.

Elevated Alpha-pregnanediol in men may indicate various conditions and hormonal imbalances. Alpha-pregnanediol is a metabolite of progesterone, a hormone present in men at lower levels compared to premenopausal women. Progesterone is essential for testosterone production and sperm development in males.
If a male's a-Pregnanediol result is too high, it could suggest several possibilities:
- Imbalance in Progesterone: High alpha-pregnanediol levels may be indicative of an imbalance in progesterone production. This imbalance could be due to various factors, such as inflammation, insulin resistance, obesity, or stress, which may lead to increased production of progesterone.
- Liver Issues: Elevated progesterone in men may also be associated with liver issues.
- Potential Root Causes: It's important to work on identifying and addressing the underlying root causes of the elevated alpha-pregnanediol levels. This might involve investigating factors such as hormone levels, stress levels, and overall health to determine the specific cause of the imbalance.
Since progesterone in men is positively associated with inflammation and can rise in response to higher testosterone production, high stress, and high cortisol levels, it is crucial to assess these factors and any related medical conditions.
In cases where supplementation of oral progesterone or pregnenolone is used, it's important to be aware of their potential effects, as they may lead to an increase in the neuroactive steroid allopregnanolone, which can have calming and anxiolytic actions.
It's essential to remember that elevated alpha-pregnanediol levels alone do not necessarily indicate a specific medical condition but can serve as a marker for further investigation into hormonal imbalances and potential underlying health issues.
