The issue of phthalate exposure!


Hello Doctor: I hadn't paid much attention until recently when I became aware of phthalates, and I noticed that my penis size is quite small.
When not erect, it measures about 5 to 6 centimeters in length and approximately 2.5 centimeters in width.
When erect, it can reach about 11 to 13 centimeters in length and around 4 centimeters in width! I masturbate about 3 to 4 times a week, and sometimes when I'm close to ejaculation, I stop and repeat the process 2 to 5 times before finally ejaculating.
Additionally, there are times when I feel that my erection isn't very firm! After ejaculation, it becomes soft...
Sometimes, I have to stand for half a minute before I can urinate! So I would like to ask if this is why my penis isn't larger? (I notice that my classmates are thicker and longer than I am) or is it related to phthalates? Furthermore, before the phthalate controversy, I had already undergone a test at Chang Gung Memorial Hospital in Kaohsiung, and my kidneys were fine! However, the urination issue is strange...
I feel like I can't urinate properly...
That's why I'm consulting you, Doctor! Should I undergo further investigation?

The size of the penis has been the subject of a large-scale screening in Taiwan.
You can check online for more information.
As for whether it is caused by plasticizers, I am not sure.
However, it is advisable to check if hormone levels are normal.
In daily life, it is best to avoid overly seasoned foods.
Strongly flavored, spicy, or rich foods may lead to issues.
If there are any unclear points, feel free to ask again, and we can discuss and research further.
This response is from Dr.

The concerns you have raised regarding phthalates and their potential impact on male urogenital health are quite valid and warrant a thorough understanding. Phthalates are a group of chemicals commonly used as plasticizers in various products, including toys, food packaging, and personal care items. They have been associated with a range of health issues, particularly concerning reproductive and developmental health.

Firstly, it is important to note that phthalates can disrupt endocrine function. They are known as endocrine disruptors, meaning they can interfere with hormone levels and signaling in the body. In males, exposure to phthalates has been linked to reduced testosterone levels, which can affect various aspects of male reproductive health, including libido, erectile function, and sperm quality. Studies have shown that higher levels of phthalates in the body can correlate with lower testosterone levels, which may contribute to issues such as reduced penile size or erectile dysfunction.

Regarding your specific concerns about penis size and erectile function, it is essential to understand that penis size can vary significantly among individuals and is influenced by a combination of genetic, hormonal, and environmental factors. While phthalate exposure may contribute to hormonal imbalances, it is unlikely to be the sole factor affecting penis size. Psychological factors, such as anxiety or self-esteem issues, can also play a significant role in perceived size and erectile function.

Your mention of experiencing difficulty urinating and the sensation of incomplete bladder emptying could indicate a separate issue, possibly related to the urinary tract or prostate health. Conditions such as benign prostatic hyperplasia (BPH) or urethral stricture can lead to urinary difficulties and should be evaluated by a healthcare professional. Given your history of urinary issues and the concerns regarding phthalate exposure, it would be prudent to seek further evaluation from a urologist. They may recommend tests such as a urinalysis, ultrasound, or even a urodynamic study to assess bladder function and rule out any underlying conditions.

In terms of self-stimulation frequency, while masturbation is a normal sexual activity, excessive or compulsive behavior can sometimes lead to temporary erectile issues or desensitization. If you find that your sexual function is affected, it may be beneficial to moderate the frequency and observe any changes.

Lastly, if you are concerned about phthalate exposure, consider reducing your use of products that contain these chemicals. Look for phthalate-free options in personal care products and household items. Additionally, maintaining a healthy lifestyle, including a balanced diet, regular exercise, and stress management, can help support overall hormonal balance and reproductive health.

In summary, while phthalates may have an impact on male reproductive health, it is essential to consider a comprehensive approach that includes evaluating hormonal levels, psychological factors, and potential underlying medical conditions. Consulting with a healthcare professional will provide you with the best guidance tailored to your specific situation.
