  • Smoking may have negative effects on sperm quality

    A recent study found that that sperm of men who smoke has a greater extent of DNA damage than that of non-smokers.

    Researchers also assessed 422 proteins in participants' sperm. One protein was absent, 27 proteins were underrepresented, and 6 proteins were over-represented in smokers.

    I knew from a very early age that I wanted to go to college and have a career. It wasn't until my sophomore year in college, though, that I made the decision to pursue medicine -- a career path that would ultimately take 15 years of my life to accomplish. At age 19, however, time was not a concern to me. I had all the time in the world.
