There is no way to know exactly when you will start menstruating. But there are clues you can look for. When did your mother start her periods? If you have an older sister, when did she start? You are likely to start at about the same age.

- Can a woman get pregnant from pre-ejaculation?
Pre-ejaculate has many other names including Cowper’s fluid, pre-come, pre-cum, and speed drop. It is secreted by Cowper’s glands, and it serves to lubricate the urethra and prepare it for the passage of sperm.
Studies have shown that pre-ejaculatory fluid does not contain sperm and therefore cannot be responsible for pregnancies. Although there is no sperm [...]

- Does having a lot of heartburn mean the baby has a full head of hair?
Heartburn or acid reflux is extremely common during pregnancy. During pregnancy, the placenta produces the hormone progesterone which serves to relax the smooth muscles of the uterus. Progesterone also relaxes the smooth muscle in the sphincter between the esophagus and the stomach. This allows stomach acids to sneak up the esophagus, causing heartburn. Progesterone also [...]

- Are mosquito bites a risk of infection with HIV?
HIV is not spread by mosquitoes or other biting insects. Even if the virus enters a mosquito or another sucking or biting insect, it cannot reproduce in insects. Since the insect cannot be infected with HIV, it cannot transmit HIV to the next human it feeds on or bites.

- Why shouldn’t pregnant women dye their hair?
There are several studies that look at the relationship between maternal hair dyes and childhood diseases, including childhood brain tumors.

- Why do you have a “bionic” sense of smell when you are pregnant?
The journal Chemical Senses isn’t usually at the top of my reading list, but it certainly came in handy to answer this question. In 2004 it published an article entitled “A Longitudinal Descriptive Study of Self-Reported Abnormal Smell and Taste Perception in Pregnant Women.” The article described the “odor hedonics” of pregnancy. Say what? I [...]

- Is it true that some people eat the placenta?
The closest thing that we found when looking for documentation of human placentophagia was that certain mammals do eat the placenta. Oh, and Billy’s friend Gail likes Polenta. But that really doesn’t have much to do with the answer.
The internet has many references to eating the placenta and recipes abound. It is unclear whether this [...]

- Should you eat a lot of carbohydrates the night before a marathon?
If you plan to run the New York City Marathon this year, you should reserve your Saturday night for the annual marathon eve dinner at Tavern on the Green.

- Do animals masturbate?
Yes, animals masturbate, as anyone with a leg that has been vigorously humped by a randy Jack Russell terrier will readily attest. (I know, humping may also be a form of play and an expression of dominance, but it’s obviously sexual, and some dogs have orgasms doing it, so let’s be real about it.)
According to [...]

Poor poor toads. They seem to always take a backseat to frogs. Frogs get kissed and turn into princes and turn into princes and toads just get to cause warts. Well, here is some good news for toads. Toads do not cause warts. Toads do, however, produce a substance from the parotid gland behind the [...]

All you have to do is listen to Billy and his wife sing in the car and you will know that the answer is yes.

- Is a dog’s mouth clean?
Joel leyner propounded two axiomatic truths for the entirety of his son Mark’s childhood: 1. Someday every single person will possess his or her own helicopter and commute to work in it; and 2. A dog’s mouth is actually cleaner than a person’s. well, so much for fatherly wisdom. Although Leyner never really bought the [...]

- Are more babies conceived during a full moon?

Studies show absolutely no correlation between the moon and pregnancy. This is another one of those old wives’ tales [...]

- Does standing on your head after sex increase your chances of becoming pregnant?
Getting pregnant can be tricky business for some. As couples are trying to conceive at older ages, the process has become more regimented, mechanical, and scientific.
