If you need another reason to keep your weight down, especially this holiday season, use better sex as your motivator! As stated in the December issue of
Glamour magazine, research shows that sustaining a healthy weight can actually boost sex drive and fertility in both men and women. Mary Jane Minkin, MD, explains that extra body fat makes extra estrogen which has the ability to hinder ovulation in women, and new research reveals that those excess pounds on men could damage their precious
sperm.

If your
period has ever been late, you know how scary and stressful it can be if you're not trying to get pregnant. Knowing some basic facts about sperm and the male body can help prevent an unexpected pregnancy, or help you avoid the anxiety of worrying that you are pregnant. So take this short quiz to make sure you're up on your sperm smarts.

Many people think men have it a lot easier than women when it comes to making babies, but they have to do their part as well — especially when it comes to taking care of their sperm, since so many things can affect them.
Eating soy may decrease their sperm count, spending too much time in
hot tubs can also have the same effect (although temporarily), and now men have to worry about their cell phones. Yep, it's true.

With all this talk about meat and dairy products causing heart problems, high blood pressure, and high cholesterol, more people are switching to alternative foods made with low fat, high protein soy. Tofu, soy milk, and fermented soy products such as tempeh, miso soup, and soy sauce are just a few, and so many people are adding them to their diets to be healthier. Some rumors have been spread that eating soy causes breast cancer, but right now the
American Institute for Cancer Research says that there's no evidence that proves this theory.

A while ago, I answered a question about a woman who was dating a
guy who lost both of his testicles in a car accident. It wasn't clear if this man could have an erection or an orgasm, but that post brought up many questions about orgasms and how it's possible to have one if you don't have any semen.
Here's the deal.

Dear Sugar,
I have been with the same guy for five years and never once got pregnant and we have unprotected sex all the time. Why have I not gotten pregnant? I'm worried that I can't have kids, and if not, what do I do?

I'm sure you've heard that men shouldn't hang out in hot tubs because it can affect their
sperm. Is this true or a myth?
Earlier this year, a team of urologists at the University of California conducted a
study to test this speculation.

I've been talking a lot about many forms of birth control including
hormonal ones like the

Emergency contraception, also called
Plan B can be a total life saver if your birth control fails you. Contrary to popular belief, Plan B is not an abortion pill - it's simply 2 little pills that contain levonorgestrel, the same hormone found in regular birth control pills, but just a stronger dose. When taken within 72 hours of unprotected sex, they can prevent the fertilization of your egg.

If you're sick of using regular condoms while having sex, but still want to be protected against sexually transmitted infections (
STIs) like HIV, the
female condom might be the answer.
The female condom (also called the internal condom) is about 6.5 inches long and at each end there is a flexible ring. One end is closed and that's the ring that gets inserted into your vagina, much like you would insert a
diaphragm - this ring is also removable.
