Sex in (floral) advertising

Sex in (floral) advertising

Having a wingman can be helpful, but for many plants it’s absolutely crucial. Flowering plants don’t have smoky bars, speed dating or eHarmony. They have to rely entirely on their tiny wing—well, I guess “men” isn’t really appropriate. But unlike your witty friend who backs you up in the bar, pollinators don’t help plants with their … Continue reading

OMG. Sugar is poison!?

OMG. Sugar is poison!?

Toxic. It’s a bad word, right? If something is toxic, or poison, it will kill you. Period. Arsenic? Poison. Water? Not poison. See? Easy! How about this one: sugar. Well, if we’re to believe everything we read in the media, sugar is one of the worst poisons there is. And you’re killing yourself with it … Continue reading

What your testicles taste

What your testicles taste

Most people probably think of tastebuds as existing only on their tongues, but did you know there are taste buds in testes? It’s true. Sort of. They aren’t exactly like the taste buds in your mouth. Male germ cells–the cells that are destined to become sperm–have molecules on them that can detect bitter tastes. These … Continue reading

Fertile eggs created from stem cells

Fertile eggs created from stem cells

You may read about this paper already, about scientists turning stem cells into fertile eggs (for example, this article at NPR). And of course, it deserves the hype. This is certainly a big breakthrough in stem cell research–especially induced pluripotent stem (iPS) cell research. iPS cells are similar to embryonic stem cells, except that they … Continue reading

Sperm tracked in 3D

Sperm tracked in 3D

Despite referring to sperm as “sperms”, this paper showing 3D tracking of human sperm swimming paths is pretty cool. Actually, I take that back. Calling them sperms definitely adds to the awesomeness. I won’t pretend to fully understand the physics behind their method, but it’s obvious that this imaging method will be important for many … Continue reading

Male contraception: a new advance

Male contraception: a new advance

Good news, guys: one day soon you may not have to worry about whether your girlfriend remembered to take her pill. The bad news? You might actually have to be the one who remembers to take it. A group of researchers at Baylor College of Medicine in Houston, the Dana-Farber Cancer Institute in Boston, and … Continue reading

Slicing up seminal proteins

Slicing up seminal proteins

While I don’t doubt that you have all been eagerly awaiting an update to my ‘Publications’ page, some of you may not have noticed that it has finally arrived. After only about 5 and half years in graduate school, I finally have my very own first-author research article. Why did it take so long? Believe … Continue reading

What mountain climbing does to your sperm

What mountain climbing does to your sperm

Thinking about taking a romantic excursion up in the mountains? If you’re trying to get pregnant, this may not be the best strategy. A study published in the Journal of Assisted Reproduction and Genetics has linked being at high altitudes with low sperm DNA quality.  Why did they choose focus on high altitudes? Previous research had shown that … Continue reading

Save some of that sperm for later

Save some of that sperm for later

In spiders, there are many species where the males only get one chance to pass on their genes. They stop making sperm as soon as they become adults, and after one sexual encounter, their sperm are all used up. In the great game of evolution, this isn’t the best strategy. They’ve quite literally put all their eggs in one basket. … Continue reading

Eating mussels can make your semen radioactive!

Eating mussels can make your semen radioactive!

They say you are what you eat and, according to new research, eating foods high in radioactive polonium-210 will make your semen radioactive, too. The work was published in the Journal of Environmental Radioactivity by Alphonse Kelecom and Ridta de Cássia dos Santos Gouvea. They measured the polonium-210 (Po-210) levels in the semen of 5 … Continue reading

Could cell phone use reduce male fertility?

Could cell phone use reduce male fertility?

For men, using a cell phone could damage your chances of having a baby. Even though cell phone use was linked to higher levels of testosterone, in a recent study at Queen’s University in Canada, it was also linked to lower sperm quality. Men who reported cell phone use had lower levels of luteinizing hormone, … Continue reading

New research throws male fertility a bone

New research throws male fertility a bone

We’ve all heard that ‘milk does a body good’, but now there’s new incentive for men, in particular, to keep their bones healthy. New research has found that a hormone produced by bones is needed for testosterone production in males. In a paper published in the journal Cell on March 4, scientists showed that male mice that don’t … Continue reading
