Does black goat improve fertility?

Black Goat Does Not Help with Fertility

Based on the available evidence, there is no scientific support for the use of black goat as a treatment for fertility issues, and herbal therapies in general are not recommended for treating male infertility due to very low quality evidence. 1, 2

Evidence Against Herbal Treatments for Fertility

The World Health Organization (WHO) and European Association of Urology (EAU) guidelines strongly recommend against the use of herbal therapies for treating abnormal semen parameters and male infertility. This recommendation is based on:

• Very low quality evidence from available studies 1
• Poor methodological quality of most studies on herbal therapies 1
• Heterogeneity of trials that does not allow for robust conclusions 1
• Lack of standardized techniques to measure outcomes between trials 1
• Adverse effects reported in 16.6% of herbal therapy studies 2

Specific Issues with Herbal Treatments

The evidence highlights several concerns with herbal treatments for fertility:

• Only one of three (33.3%) studies on herbal therapies reported a positive influence on pregnancy rates 1
• Some herbal compounds have been associated with adverse hematological reactions, as seen with Linn Crocus sativus (Saffron) 1
• There is often a lack of clear pre-selection of appropriate subgroups for testing 2
• There are no high-quality data to support the use of any specific herbal treatment 1

Evidence-Based Approaches for Fertility

Instead of herbal treatments, the guidelines recommend several evidence-based approaches:

1. Lifestyle modifications:

   • Weight loss for overweight/obese individuals 1
   • Physical exercise 1
   • Smoking cessation 1
   • Diet lower in fats and higher in fruits and vegetables 2

2. Medical evaluation and treatment:

   • Comprehensive semen analysis with adherence to WHO reference values 1
   • Hormonal evaluation 1
   • Treatment of underlying conditions (e.g., hypogonadism) 1, 2

3. Antioxidant therapy:

   • While evidence is conflicting, some studies suggest antioxidant therapy may improve seminal oxidative status 1
   • However, there are insufficient data to recommend any specific antioxidant or combination 1

Pitfalls and Caveats

When considering fertility treatments, be aware of these important caveats:

• Semen analysis alone cannot distinguish fertile from infertile men 1
• Techniques to measure oxidative stress and antioxidant capacity are not standardized between trials 1
• Despite promising animal studies, many herbal treatments lack human clinical evidence 1
• Some herbal treatments may have adverse effects that outweigh any potential benefits 1, 2

Future Research Needs

The guidelines emphasize the need for:

• Large, well-designed placebo-controlled randomized trials 1
• Primary outcomes that measure time to pregnancy and live births 1
• Standardized methods to measure oxidative stress 1
• Better characterization of patient subgroups 1

In conclusion, there is no scientific evidence supporting the use of black goat for fertility improvement, and herbal therapies in general are not recommended for treating fertility issues due to poor quality evidence and potential for adverse effects.
