Which sex is better for sperm?

Researchers at Duke University have developed a novel way to measure sperm quality in a new study that will help doctors identify the best test for sperm quality.

The researchers found that testosterone levels in men with normal sperm production were lower than those with abnormal levels, which could potentially lead to infertility.

The research was published in the journal Nature Methods.

The researchers compared the sperm levels of about 5,000 men with no detectable testosterone levels to the semen of men with high levels.

They found that men with low levels of testosterone had lower sperm production than men with higher testosterone levels.

Men with low testosterone also had lower levels of motility, which is a type of chemical that helps sperm to move through the reproductive tract.

The team also found that those with low motility had lower testosterone levels than men who had high levels of it.

“This is a very exciting finding,” said the lead author, Andrew W. Mollison, a professor of molecular biology at Duke.

“Sperm production is related to testosterone, but we don’t know what’s the most effective way to produce testosterone.”

This is the first study to use a sperm test to measure testosterone levels, and it is the largest study to examine sperm quality, Mollinson said.

He added that the new test could be used to screen for conditions that can cause infertility, such as the aging of the body or low sperm count.

“There are a lot of different ways to measure these things, and they all depend on how you measure them,” Mollisson said.

“It’s not as simple as you measure testosterone in the blood and it says, ‘You have testosterone.'”

In addition to testing for testosterone, Mullinsons team also used a variety of other biomarkers to assess sperm quality including levels of sperm motility and sperm morphology.

They also used genetic tests to analyze sperm production and motility.

Mollison and his team measured testosterone in sperm from men who were of European descent and who had normal semen quality.

They used sperm collected from the same men every other week for about a year to determine the levels of the three primary markers of sperm production: sperm motile capacity, sperm morphology and testosterone levels (both naturally and in response to a drug).

These markers of motile and sperm quality were measured by using a technique called immunoassay.

They were tested in semen from the participants and compared with semen from other men who matched the participants.

The results showed that testosterone in normal men is associated with lower sperm quality than in men who have high testosterone levels and who have lower sperm motiles.

The study also found an association between testosterone levels but not testosterone levels alone.

“When you look at the results from men with testosterone levels below the normal range, testosterone levels are associated with low sperm production,” Mollsison said.

The relationship between testosterone and sperm production was stronger in men of European ancestry than in other groups.

In addition, the researchers found a correlation between the two biomarkers of motiles and testosterone.

The higher the testosterone levels were, the lower the motile quality was.

The association was weaker in men without any testosterone levels at all.

In the future, the team plans to use the new testosterone assay to screen men with elevated testosterone levels for conditions such as high testosterone, low sperm motilia and low sperm counts, Mollsisons said.

CNN title Apple ‘Electronics Store’ to open in California article The electronics store is set to open its doors at a new location in California’s Central Valley next year, according to a report.

The site will be called “Electronic Component Store” and will open in the California Central Valley, according TechCrunch.

The news comes as Apple prepares to launch its new iPhone X and iPhone XS models in the US next month.

The new iPhone will be priced at $999, with a 3G version priced at an even higher price of $1,199.

The iPhone X is set for release on October 23, with the iPhone Xs and XS Max also expected to arrive in the same month.

When you build a mountain bike, there are few things as important as the components that make up it

The Washington Times article article In the beginning, the components on a mountain biker’s frame were small.

It wasn’t until the 1970s that manufacturers began building the components to build a bike with more horsepower, better handling, better braking and better aerodynamics.

But even then, the biggest challenge was figuring out how to build them into a bike that would actually be capable of riding the road.

At the time, the U.S. government mandated the development of a motorcycle that could run on electric power.

The first motorized bike in America was the Ford Mustang, powered by a 500-horsepower, four-cylinder engine.

The Mustang was the first to hit the road, but the bike had a lot of limitations.

For one thing, it was a huge car.

As a passenger, the car had a range of roughly 100 miles and the rider could only travel about five miles per hour.

On a road trip, you’d want to go as fast as possible to get to the next town, and you couldn’t be certain you’d hit your destination before it was too late.

Motorcycles were bulky, noisy, expensive, and limited the rider’s range.

By the 1970, the Honda S1000RR had been out for more than two decades and had been replaced by the Honda CR-V.

The Honda CRV was a mass-market motorcycle that featured a much bigger engine, which allowed the bike to run on much more power.

That power allowed it to be able to do things that a bike could never do.

The S1000R also had a much wider track, which made it much faster.

The power also made the bike a lot more comfortable for the rider.

It was a big step in terms of getting a mass market motorcycle into the hands of the American public.

In the 1970’s, American motorcycle manufacturers began to look to Asia for their next big motorcycle.

China was a market that could offer a mass consumer base.

So they began to make bikes there, starting with the Honda P1.

This bike was based on the Honda F1 racer, and it was the world’s first mass-produced motorcycle, as well as one of the most successful, selling millions of units.

The American market for motorcycles continued to grow, and the American market eventually had the world market for bicycles.

The U.K. had already been a market for electric bikes for decades, but its electric market had only begun to grow in the 1990s.

The United States had just begun to enter the electric market, and as more and more electric cars were made, the market began to shrink.

In 1990, the electric car market was worth $11 billion, making it the largest consumer market in the world.

Today, there is less than $1.5 billion in the U and U.N. markets for electric cars, but electric bikes account for about half of that market.

The bike’s powertrain was one of its big selling points.

The electric bike was a very low-profile and lightweight design, designed to be a compact machine that could handle the most difficult of jobs.

The idea of using the same battery technology as electric vehicles, and then using the bike’s own battery to provide power to the engine, was revolutionary.

It also gave the bike some of the highest safety ratings of any electric vehicle on the market.

In addition to a battery, the bike needed to be capable, with the right technology, of running at the maximum speed.

But for most Americans, this was not enough.

Motorcyclists were often referred to as “bums” and, because they were usually riding on narrow, paved roads, their bikes were not very safe to ride.

Many of them were killed or seriously injured in accidents.

For the first time in decades, the United States began to recognize the need for more bike safety standards.

In 1996, the first of the nation’s first national bicycle safety standards was created.

It required electric bikes to have at least four safety features.

For most people, four safety systems would not be enough to make a difference, but it was an important step in the right direction.

In 1997, the National Highway Traffic Safety Administration began regulating the operation of electric bikes in the United State.

In 1999, the nation introduced the first national law to limit the use of lithium ion batteries for the powertrain of electric motorcycles.

The law, known as the Battery and Electric Vehicle Safety Act, was passed by Congress in 1999 and went into effect in 2001.

At that time, electric bike manufacturers were allowed to sell their bikes in any state they chose.

The only requirement was that the bikes were built in the states where they were sold.

The rule also mandated that they had to be sold in California, which was home to most of the country’s battery manufacturing plants.

In 2002, the law was expanded to include motorcycles built in Japan and South
