Men + Cell Phones Equals… Male Infertility?

Friday, June 24th, 2011

There are many reasons that people eschew adopting technology, including heavy cell phone usage. First, it can be quite risky to use a cell phone during driving. It can also be socially rude to sit in company chatting or texting… all the while avoiding one’s companions! And some medical professionals are even saying that it can have a significant impact male infertility.

A recent study on men who were talking on their cell phones an “excessive” amount of time showed higher-than-normal levels of testosterone and lower levels of LH, a reproductive hormone. Thus, their sperm counts (and amount of healthy sperm) were significantly decreased, enough to cause male infertility in some.

The problem, according to Queen’s University, Australia, researchers appears to be abnormal testosterone levels associated with very high cell phone usage. Of course, why this is happening isn’t cut and dry. That’s why studies are being conducted across the globe to address the strange phenomenon. After all, it could be that men with naturally higher testosterone levels engage in more intense cell phone usage than their counterparts with lower testosterone levels.

Until it’s clear whether or not cell phones are, indeed, a contributing factor to male infertility, it may be a good idea to follow these simple guidelines, which are safety-first anyway:

1. If you cannot be free from your cell phone, you may have the beginnings of a problem or true addiction. Take breaks from being “on call” 24/7, as it will be good for your mental health, if nothing else!

2. Don’t keep your cell phone in your front pocket or on your lap. Some research has shown that low levels of radiation are emitted from cell phones; thus, they should be kept far away from genitalia.

3. If you’re having trouble with male infertility, don’t stop using your cell phone, but do ask your fertility specialist if he or she thinks it could be a problem. Not all will agree with the researchers, but it’s worth considering every possibility.

Spermatogenesis Research May Help Advance Male Infertility Treatments

Wednesday, April 6th, 2011

In medical news…

Japanese researchers have reproduced sperm in an effort to better understand the process of spermatogenesis and possibly help increase infertile men’s abilities to naturally reproduce.

During numerous experiments, test tube-created sperm from infant mice cells were developed “artificially” in the lab environment and subsequently injected into female mice ova.  The result?  Healthy mouse babies that were all born fertile themselves.

Though this research has not been tested on other animals (and certainly not humans), the implications for men suffering from male infertility (or who may suffer from male infertility, as would be the case with young men undergoing cancer treatments) are abundant.

The Japanese scientists are highly encouraged by the idea that freezing testicular tissues before any male infertility issues arise (e.g., prior to chemotherapy or radiation), sperm can later be made in the laboratory and then used to fertilize eggs.

 Quick stat:

 Male infertility is estimated to affect approximately 30% of men around the world.  Although most are what is considered to be “sub-fertile”, around 2% of all males are entirely infertile.

Pop Star Kylie Minogue Considering Egg Donor to Have Baby

Monday, December 13th, 2010

Kylie Minogue, the pop singer from “Down Under” who stole America’s collective heart in the late 1980s is now 42 and may soon be the latest star to try fertility treatments.

Minogue has announced she’s seriously considering working with an egg donor so she can conceive.  She’s concerned that chemotherapy and radiation as a result of treating breast cancer in 2005 has most likely left her unable to have a baby naturally. 

Minogue’s age could also play a factor.  Studies have shown that women over 40 have a decreased likelihood of being able to get pregnant.  Thus, fertility treatments could provide an effective solution.

Though Minogue hasn’t made an official decision, we’ll definitely keep you posted!

Embryo Frozen 20 Years Still Viable

Friday, October 22nd, 2010

In news that pleasantly surprised fertility specialists around the globe and heartened would-be parents, an embryo that had been frozen for 20 years was used to fertilize a 42-year-old woman who could not conceive naturally.  (The two-decade old embryo was from an unrelated donor.)  The woman is a resident of the United States and gave birth in May to a healthy boy.

The news item raises some interesting questions, including how long an embryo can stay viable while frozen.  Some fertility doctors speculate that 20 years isn’t even close to the length of time that’s potentially possible.  One recent study even estimated that the passage of 40 years wouldn’t be a problem if the embryo had been stored correctly.

This gives great hope to women who decide to freeze their eggs at an early age if they know they are going to undergo a procedure such as radiation or chemotherapy which can rob them of their fertility.  Using a surrogate, if necessary, they can use their own frozen embryos to create new life. 

Men, Infertility and Cancer

Saturday, July 10th, 2010

Men who expect to one day become fathers may have serious decisions to make if they are diagnosed with cancer, as many types of treatment options can leave a cancer patient infertile.

How quickly does the process of infertility happen?  Some researchers say that within a week of undergoing radiation or chemotherapy, a male’s infertility can be seriously — or entirely — compromised.

The phenomenon isn’t limited to testicular cancer, either, because it’s not where the cancer strikes that’s at issue; it’s what kind of remedy is chosen to eradicate (or slow) the cancer cells.

Though men who have been diagnosed as having cancer are usually not considering future concerns such as whether they can have children, it may be worth investigating options, such as the freezing of healthy sperm pre-treatment

Cyclist Lance Armstrong did before he underwent treatment to deal with his cancer, and other men around the world have done so, too.

Certainly, the foremost goal is to attack the cancer.  But it’s worth thinking long-term, too.

  • Cell Phone Use and Male Infertility

    Friday, July 10th, 2009

    Guys who use their cell phone for prolonged periods of time may be inadvertently contributing to their infertility problems.  So says a news item from WebMD

    Holding the cell to one’s ear isn’t the culprit; it’s when hands-free devices are used (think Bluetooth) and the cell phone is placed in the man’s lap (if sitting), in his pocket or snapped on his waistband.  Small doses of radiation from the cell phone can actually contribute to male infertility, according to researchers.

    As noted in the article:

    Semen exposed to radiofrequency electromagnetic waves emitted from cell phones had higher levels of damaging free radicals, lower sperm motility (the ability of the spermto move and swim) and sperm viability (the percentage of live sperm), and possibly greater oxidative stress…

    For men and their partners who are having trouble conceiving naturally, these findings may provide a clue to their personal fertility mystery.
