What is a one-sentence summary of the following article?
Some medications or supplements that you're taking to treat another condition may have side effects that decrease your fertility. If you tell your doctor all medications and supplements you're taking, they can identify any that might be causing infertility. Your doctor can work with you to find a different medication or treatment method that will improve your condition without adverse effects on your fertility. After you discontinue medications or supplements, it may be a few months before you have any real changes in your fertility. Both alcohol and nicotine have negative effects on fertility. The less you consume of these substances, the better your chances of conceiving. If you smoke, it may take longer for you to be able to conceive safely, particularly if you quit with the help of nicotine replacement therapy, such as the patch. If your usage of alcohol is excessive or problematic, you may require additional assistance to stop drinking. Don't be afraid to ask for help. Your doctor may have some recommendations. Keep in mind that even if you vape, if you're still ingesting nicotine, it may cause problems with infertility. If you have a body with a penis and testicles, hot tubs and extremely hot showers can lead to infertility. The heat kills sperm and can substantially decrease your sperm count. Using hot tubs frequently can also lead to problems with infertility if you have a body with ovaries, although the risk is not as significant as it is for bodies with testicles. Obesity can cause infertility regardless of your reproductive organs. Your doctor can help you come up with an exercise and diet plan that will help you lose weight and keep it off. They may also refer you to a physical trainer or a nutritionist for additional guidance. If you've never exercised or it's been a while, start slow. It will take some time for your body to adjust to increased activity. Start with short, 5-minute walks several times a day. If you have joint problems, low-impact exercises, such as biking or swimming, may be a better fit for you. Stress has a negative effect on fertility. If you've been trying for years to get pregnant and not having any luck, the anxiety that produces also may not be helping matters. Try deep breathing exercises several times a day to reduce your physical stress. You may also want to try meditation. Start slowly, meditating for only a couple of minutes each day, then gradually increase your time. You can also combine your deep breathing exercises with your meditation. Counting breaths gives you something to focus on so you can more easily clear your mind.

Summary:
Discontinue medications that may affect fertility. Reduce or eliminate your consumption of alcohol and nicotine. Avoid hot tubs or hot showers. Start a regular exercise program if you're overweight. Practice relaxation techniques to reduce stress in your life.
