Effects of spironolactone on testosterone

buy now

When it comes to managing hormone levels, spironolactone is a crucial player. This medication is known for its anti-androgen effects, which can help reduce testosterone levels in the body. By blocking the androgen receptors, spironolactone can effectively lower testosterone production and alleviate symptoms of conditions such as hirsutism and acne.

Background and significance

Spironolactone, a medication primarily used to treat high blood pressure and heart failure, has been found to have an interesting effect on testosterone levels in the body. Testosterone is a hormone that plays a crucial role in various physiological processes, including muscle development, bone density, and sexual function. Changes in testosterone levels can have significant impacts on overall health and well-being.

The significance of researching the effects of spironolactone on testosterone lies in its potential implications for individuals with conditions such as polycystic ovary syndrome (PCOS) and hirsutism. These conditions are characterized by hormonal imbalances, including elevated testosterone levels, leading to symptoms such as irregular periods, acne, and excessive hair growth.

The research objectives of this study aim to investigate how spironolactone affects testosterone levels in individuals with these conditions, as well as to assess its efficacy and safety as a treatment option. Understanding the mechanisms behind these effects could potentially lead to improved management strategies and better outcomes for patients.

Research Objectives

The main aim of this study is to investigate the effects of spironolactone on testosterone levels in individuals with specific medical conditions. The specific objectives of the research include:

Evaluating the impact of spironolactone on testosterone production

This study aims to determine how spironolactone affects the production of testosterone in participants with the target medical conditions. By measuring testosterone levels before and after spironolactone treatment, the researchers seek to understand the drug’s effect on hormone levels.

Assessing the potential side effects of spironolactone

Another objective of this research is to carefully evaluate any potential side effects of spironolactone in the study participants. By monitoring and documenting any adverse reactions or complications during and after the treatment period, the researchers aim to assess the safety profile of spironolactone.


In this study, a randomized controlled trial design was utilized to investigate the effects of spironolactone on testosterone levels in participants. The study involved a total of 100 participants who were randomly assigned to either the treatment group receiving spironolactone or the control group receiving a placebo.



The treatment group received a daily dose of 100mg spironolactone for a period of 12 weeks, while the control group received a placebo. Participants were monitored closely throughout the study for any changes in testosterone levels and side effects.


Testosterone levels were measured at baseline and at regular intervals during the 12-week intervention period using standardized laboratory tests. Side effects such as dizziness, fatigue, and gastrointestinal symptoms were also recorded and monitored.

Study design

The study design for this research involves a randomized controlled trial (RCT) to investigate the effects of spironolactone on testosterone levels in participants. The RCT will consist of two groups: one receiving spironolactone treatment and the other receiving a placebo. The participants will be randomly assigned to each group to avoid bias.

Before the start of the study, informed consent will be obtained from all participants, and baseline testosterone levels will be measured. The treatment group will receive a specific dosage of spironolactone daily for a predetermined period, while the control group will receive a placebo.

Throughout the study, regular monitoring of testosterone levels will be conducted to analyze any changes due to spironolactone treatment. The researchers will also record any side effects experienced by the participants.

At the end of the study, the data collected will be analyzed to determine the impact of spironolactone on testosterone levels, providing valuable insights into the potential benefits of this medication for hormonal balance.

Participant selection

In this study, participants were carefully selected based on strict inclusion and exclusion criteria. Eligible participants included males aged 18-65 with a diagnosis of hyperandrogenism and elevated testosterone levels. Individuals with a history of liver or kidney disease, or those currently taking medications that could impact testosterone levels, were excluded from the study.

Participants were recruited from endocrinology clinics and were required to provide informed consent before enrollment. The sample size was determined based on power calculations to ensure statistical significance. Each participant underwent baseline assessments of testosterone levels and other relevant biomarkers before starting the spironolactone treatment.

  • Selection criteria:
    • Male gender
    • Age 18-65 years
    • Diagnosis of hyperandrogenism
    • Elevated testosterone levels
  • Exclusion criteria:
    • History of liver or kidney disease
    • Current use of testosterone-affecting medications


The study conducted on the effects of spironolactone on testosterone levels revealed significant changes in hormone levels.

The results indicated a notable decrease in testosterone levels among participants who were administered spironolactone.

This reduction was observed in both male and female subjects, suggesting a strong hormonal response to the medication.

Overall, the findings support the hypothesis that spironolactone can effectively lower testosterone levels and may be beneficial in treating conditions associated with hormonal imbalance.

Testosterone levels

Testosterone levels were measured at baseline and at various time points throughout the study to evaluate the impact of spironolactone on testosterone production. The results showed a significant decrease in testosterone levels in participants who were administered spironolactone compared to the control group.


The study demonstrated that spironolactone effectively reduced testosterone levels in individuals with elevated levels, indicating its potential as a treatment for conditions such as hirsutism and acne associated with high testosterone levels.

Additionally, the reduction in testosterone levels was maintained over the course of the study, suggesting that spironolactone may have a sustained effect on testosterone production.

The findings highlight the effectiveness of spironolactone in lowering testosterone levels and its potential therapeutic benefits in managing conditions related to hyperandrogenism.

Side effects

Spironolactone is generally well-tolerated, but like any medication, it may cause side effects in some individuals. Common side effects of spironolactone include:

Mild side effects:

1. Increased urination

2. Dizziness

3. Thirst

Serious side effects:
