A Brief History Of The Pregnancy Test

I was commenting on how packaged pregnancy tests resemble fruit roll ups when my mother told me scientists once injected bunnies with a woman’s urine to determine whether or not she was pregnant.
“A rabbit?” I was a little stunned by the idea of poor, floppy-eared, innocent rabbits getting shot up with pee. “Oh yeah!” My…

Female Orgasms: Not Evolutionarily Necessary But Definitely Awesome

Both men and women like the pleasure that orgasms bring–but only male orgasms are actually “necessary.” At least that’s what science says–because only male orgasms are needed to make a baby. And now they’re trying to figure out why we should bother caring about women’s orgasms at all.

Ah, science. Science has clearly…

Late-Night TV: India’s Latest Weapon Against Overpopulation

India has a rather novel idea to curb overpopulation — late-night TV! Health and Family Welfare Minister Ghulam Nabi Azad wants the country to increase efforts to bring electricity to the country’s rural areas in the hopes that watching late-night TV will kill the libidos of this huge population and discourage procreation. “If there i…

Sperm Are Smart Little Guys

As we learned earlier today, sperm have minds of their own. If you want to get pregnant, you might want to have sex with a specimen who is on the opposite end of the attractiveness spectrum as Brad Pitt. And, according to another study, you better hope you’re attractive. When scientists conducted researched on red…

Super Sperm

I love the scene in “Look Who’s Talking” where the basic rule of human reproduction plays out on screen: the fastest sperm wins the race to the egg. But in the animal kingdom at large, that is not always the case. Scientists have found an ancient species called Ostracods where the largest sperm won. Eve…

The Chemistry Of Kissing

Kissing might just seem like a way of passing time with the man in your life, but it really triggers a chemical response that promotes mating and reproduction. Helen Fisher, a researcher at Rutgers University in New Jersey, conducted brain imaging studies and believes a kiss, or full-on make-out session, can activate chemicals that arouse…

First Live Birth After Ovary Transplant Could Mean Older Women Having Babies Without In Vitro

Doctors in St. Louis successfully transplanted an ovary from one twin to another who had gone into early menopause at age 15. The transplanted ovary restored the woman’s full fertility and she gave birth at 38. According to researchers writing in the New England Journal of Medicine, this is the first time an entire ovary…

Men: The Weaker Sex?

According to a new study, men are fast becoming the weaker sex. In recent years, some 100,000 chemicals have entered the atmosphere and are wreaking havoc upon masculinity. Apparently, “gender bender” chemicals are messing with hormones, resulting in a “feminisation of the males.” In male animals, symptoms include testicular dysfunction, smaller penises, and reproductive challenges,…

Male Wasps Think Orchids Are Sexy

Orchids that look like female wasps make life confusing for male wasps. The men think the flowers are female wasps, therefore, they try to copulate with them, which doesn’t work very well. They just waste their precious sperm. “Unquestionably, producing sperm, ejaculate, or seminal fluids is costly for many animals,” reports the study, published i…
