The vas deferens: one of the vast differences between men and women. It is basically a small, hollow tube with the consistency of a wet noodle that allows the transit of sperm cells from the testicle on their way to the outside world to try to win the race and be the luckiest, or fittest, to reach and fertilize an egg. Why does it get so much attention in reproductive medicine?
Fitness is clearly important for men and women’s health, but what about fitness' impact on fertility? Testosterone is believed to be an important factor in a man’s fertility. Low testosterone (total testosterone level of less than 300 ng/dl by the endocrine society definition) is very prevalent in infertile men. Forty-five percent of men with no sperm in the semen, without a blockage in the system transporting sperm, have low testosterone and 43% of men with low sperm counts have low testosterone levels.
Motherhood is an experience that no one has to miss out on, even if biological factors are interfering. At Austin Fertility & Reproductive Medicine, the physicians are able to offer services of a state-of-the-art in vitro fertilization (IVF) lab called “Westlake IVF”, used for assisted reproductive technologies (ART). Dr. Shahryar Kavoussi explains what those technologies are and what steps to take when considering treatment by a fertility specialist.
Vasectomy reversals should be carried out by urology specialists with access to appropriate micro-surgical training and assisted reproductive technologies and not general urology surgeons, according to research published in the October issue of BJUI. The findings are based on a series of surveys carried out among consultant members of the British Association of Urological Surgeons (BAUS) over a ten-year period.
If you are a man with diabetes, you are twice as likely as other men to suffer from low testosterone. But does it work the other way around? Can low testosterone boost your risk for diabetes? Low levels of testosterone may affect how a man's body reacts to insulin, a hormone that helps control levels of blood sugar.
Living with erectile dysfunction, or impotence, can be a huge blow to a man's ego and, in some cases, his health. If doctors know who is at risk, they can take steps to stop erection problems. Men with periodontitis, a severe form of gum disease, may have an increased risk of impotence.
The medication Stendra (avanafil) has just been approved by the U.S. Food and Drug Administration to treat erectile dysfunction, the FDA announced today. Approximately 30 million men in the U.S. have difficulty getting or maintaining an erection, according to the FDA's release. This inability to have a satisfactory sex life can negatively impact a person's quality of life and personal relationships.
Men and women have much in common. But let's face it: there are some obvious differences between the sexes, especially when it comes to sexual health. Just as women have their own set of distinct health issues, there are many health problems that only concern men. Low testosterone and erectile dysfunction (impotence) are two prime examples of men's sexual health problems.
Male infertility (the inability to reproduce) can be caused by a number of factors, including varicoceles, or swollen veins in the scrotum. Now, it seems varicoceles may lead to problems even more severe than infertility. Varicoceles may disrupt a man's ability to produce testosterone - a hormone that is extremely important for keeping men in good health. However, surgery can boost testosterone levels in men suffering from the condition.
We know how important estrogen is for women, but did you know it’s an important hormone for men? Yup, you guys have it, too. There is an enzyme in fat cells called aromatase; it takes testosterone made by the testicles and coverts it into estrogen. The more fat cells a guy has, the more testosterone gets turned into estrogen. The less relative testosterone is kept around to act on tissues, the tougher it is to maintain muscle mass and lose fat mass. The more fat that is put on, the more testosterone is converted into estrogen, in essence dropping the testosterone level, which in turn makes it harder to burn the fat mass… and so the vicious cycle begins. That’s why hitting the gym and getting regular cardiovascular exercise to keep the waistline in check is a great way to keep more of the testosterone that’s being made as testosterone.
