Dr. Parviz Kavoussi co-authors guideline for clinicians on sperm DNA fragmentation
As 60% of couples struggling with infertility have a male factor contribution in their difficulty conceiving, higher levels of testing of the male partner is necessary. Since the 1600s, the traditional semen analysis has been the cornerstone of the male fertility evaluation. This includes measuring the semen volume, the sperm concentration (number of millions of […]
The Role of Male Sex Hormones
While female hormones may get more media attention, male hormones are just as critical to reproductive health. When the body produces too little or too much of any of the male sex hormones, it can have a detrimental effect. A thorough check-up with a urologist who specializes in male reproductive/sexual health may be the best […]
Male Infertility: What Are the Causes?
It is estimated that approximately 15% of couples will struggle with infertility. Of those couples, up to 50-60% will have at least a contributing male factor. The causes of male infertility are diverse, and can range from anatomical issues, to genetic mutations, to hormonal insufficiencies. For example, one of the most common causes of infertility […]
Most Patients See Improvement in Sperm Counts by 6 months following Varicocele Surgery
Varicoceles represent a common correctable etiology of subfertility in men, present in approximately 40% of men with primary infertility. Varicoceles may be addressed with a specialized operation that uses an operative microscope to divide the dilated veins. While it has been established that most men will have improved semen parameters following surgery for varicoceles, few […]
Men with varicoceles with testicular atrophy respond to varicocele repair
The reproductive urologists, Dr. Parviz Kavoussi and Dr. Luke Machen, at Austin Fertility & Reproductive Medicine presented their research on varicocele repair in men with testicular atrophy at the 2019 American Society for Reproductive Medicine national meeting and congress. A varicocele is an abnormal dilation of veins around the testicle which increase testicular temperatures and […]
Treatment of men with varicoceles and a sperm count of zero
A varicocele is an abnormal dilation of scrotal veins around the testicle and can decrease sperm counts, sperm motility, and morphology. Varicoceles can also cause increased damage to the DNA of sperm cells, having an adverse impact on fertilization, pregnancy, and miscarriage rates. Fifteen percent of men in the general population have a varicocele and […]
Varicoceles can induce severe testicular injury resulting in sperm counts of zero with Sertoli Cell only
Approximately 1% of men in the general population in the United States have a sperm count of zero. It is remarkably common considering that is one out of every 100 men. Fifteen percent of men in the general population have a varicocele, an abnormal dilation of veins around the testicle which can adversely impact sperm […]
Damaged sperm DNA may contribute to recurrent pregnancy losses
Dr. Parviz Kavoussi was interviewed in Fox 7 news regarding the impact of sperm DNA damage on recurrent pregnancy losses. Multiple studies have reported that men with high percentages of their sperm with DNA fragmentation have a higher risk of contributing to recurrent miscarriages. Dr. Kavoussi states, “The good news is now that we can […]
Advanced paternal age’s potential impact on neonatal and maternal outcomes
Dr. Parviz Kavoussi was recently interviewed live on NBC’s KXAN network regarding a recently published study evaluating outcomes of neonates and mothers when the male partner was considered to be in an advanced paternal age range at the time of conception. This study looked at a birth registry which included over 40 million documented births […]
Why Younger Men Should Care about Low Testosterone
Having low testosterone (low T) levels is usually considered a problem in older men. In fact, men over the age of 40 begin experiencing a 3 percent reduction in testosterone levels. However, younger men can also have lower testosterone levels, which can have a big impact on male fertility. Causes of Low T Levels […]
