Q: Does Smoking, Drinking, and Frequent Sex Affect Male Fertility?

Is this harmful to the body?

Hello, Dr.
Hsu.
I have a few questions regarding sexual health.
My boyfriend is 32 years old and works as a police officer.
He has a habit of smoking about a pack a day and occasionally drinks alcohol.
Due to his work schedule, he often stays up late.
We have been together for almost six months and have not used contraception, but we have not become pregnant.
Does smoking, drinking, and staying up late reduce sperm count or lead to infertility?
Additionally, because of his job, we can only see each other about once every three days, but during our one or two days off, we have intercourse 3 to 4 times, totaling about 7 to 8 times a week.
There have been no issues with premature ejaculation or inability to ejaculate, and his erections are good.
Given his age, is this frequency of sexual activity excessive and could it negatively impact his health? He is quite concerned that this might be excessive indulgence and wonders if it could lead to any health problems.
What is a normal ratio of age to frequency of sexual activity?
Also, could this frequent ejaculation affect sperm count and impact fertility? I have heard that if a man drinks alcohol before intercourse, it can affect the ability to produce sperm afterward.
Is it true that having sex after drinking is harmful to health? I apologize for the many questions, but I would appreciate your insights.
Thank you!

Xiao Yu: Hello, there is a saying: "When one is well-fed and warm, they think of lust." From a urological perspective, this statement is quite appropriate.
Sexual function is not directly related to life itself; therefore, it only manifests normally when the body is in good condition and life is not threatened.
To clarify, as long as one can achieve a normal erection, it indicates that the body is functioning well.
Regarding whether indulgence in sexual activities can deteriorate health, traditional Chinese medicine has its views, but Western medicine does not agree.
On the contrary, Western medicine believes that as long as one desires to engage in sexual activity and the body can handle it, the frequency of sexual activity does not negatively impact health.
Some people feel satisfied after one bowl of food, while others may need three or four bowls.
You cannot say that those who eat more are healthier.
Under normal circumstances, the frequency of sexual activity does not affect health (although stimulation through medication can have an impact).

Alcohol, in fact, can be beneficial for sexual function.
Provided that one is not intoxicated, moderate alcohol consumption can enhance the sensations for both men and women, making sexual activity more enjoyable.
According to studies, 50% to 60% of women report that they find it easier to reach orgasm after drinking, while about 30% to 40% of men feel that a little alcohol helps them achieve erections more easily and last longer.
Therefore, moderate alcohol consumption is generally considered to be aphrodisiac.
Of course, excessive drinking or intoxication can lead to negative effects.
Frequent ejaculation can indeed affect sperm count, and an irregular lifestyle can impact both the quality and quantity of sperm.
Generally, sperm takes about 70 days to mature, and during this two-and-a-half-month period, any physical issues or psychological stress can affect the quality of the sperm produced.
Remember what I mentioned earlier: "When one is well-fed and warm, they think of lust," which illustrates this point.
In other words, if someone has been ill, it will take about two and a half months for the sperm to return to its previous condition.
As for the issue of not achieving pregnancy, it is advisable to conduct a semen analysis first; if the results are normal, then the female partner should be examined, but I won’t elaborate further on that here.

More Info

When considering the impact of smoking, drinking, and frequent sexual activity on male fertility, it's essential to understand how these factors interact with reproductive health. Your boyfriend's lifestyle choices, including smoking a pack of cigarettes a day, occasional drinking, and irregular sleep patterns due to his job, can indeed affect his sperm quality and overall fertility.

Smoking and Male Fertility
Research has shown that smoking can significantly reduce sperm quality. Nicotine and other harmful substances in cigarettes can lead to decreased sperm count, motility (the ability of sperm to move), and morphology (the shape of sperm). The toxins in cigarettes can also cause oxidative stress, which damages sperm DNA. This damage can lead to fertility issues and may also affect the health of any potential offspring. Given that your boyfriend smokes regularly, this could be a contributing factor to the lack of pregnancy despite unprotected intercourse.

Alcohol Consumption
Moderate alcohol consumption may not have a significant impact on fertility, but excessive drinking can lead to hormonal imbalances that affect sperm production. Alcohol can lower testosterone levels, which is crucial for sperm production and sexual function. While occasional drinking may not pose a significant risk, regular heavy drinking can lead to fertility issues. It's important to note that alcohol can also affect sexual performance and libido, potentially leading to difficulties in achieving or maintaining an erection.

Frequency of Sexual Activity
Regarding the frequency of sexual activity, having sex 7-8 times a week is generally considered normal for a healthy couple, especially at your boyfriend's age of 32. As long as both partners feel comfortable and satisfied, this frequency should not inherently cause health issues. However, frequent ejaculation can temporarily reduce sperm count, as it takes time for the body to replenish sperm reserves. Sperm production typically takes about 70 days, so if your boyfriend is ejaculating frequently, it might lead to a temporary decrease in sperm count, but this is usually not a long-term concern unless there are underlying health issues.

Impact of Lifestyle on Sperm Production
The combination of smoking, drinking, and irregular sleep can lead to a decline in overall health, which in turn can affect sperm quality. Chronic stress, poor diet, and lack of exercise can also contribute to fertility issues. It's crucial for your boyfriend to consider making lifestyle changes, such as quitting smoking, reducing alcohol intake, and improving sleep hygiene, to enhance his reproductive health.

Conclusion
In summary, smoking and excessive alcohol consumption can negatively impact male fertility by reducing sperm quality and quantity. While frequent sexual activity is generally not harmful, it can lead to temporary reductions in sperm count. If pregnancy is a goal, it may be beneficial for your boyfriend to adopt healthier lifestyle habits, including quitting smoking and moderating alcohol consumption. Additionally, if there are ongoing concerns about fertility, consulting a healthcare professional for a semen analysis and further evaluation would be advisable. This proactive approach can help identify any underlying issues and improve the chances of conception.
