Dr. Parviz Kavoussi co-authors research paper evaluating cytocentrifugation to help isolate sperm cells.
In men diagnosed with azoospermia (sperm count of zero in the semen) by the standard recommended laboratory procedure, a few sperm cells may be identified in the semen following additional centrifugation. When these very few sperm cells are found, the diagnosis is changed from azoospermia to cryptozoospermia. Dr. Parviz Kavoussi co-authored a research paper assessing […]
Dr Parviz Kavoussi leads conference on medical treatment for male infertility
There are a lot of misconceptions about medications that can improve male infertility. Unfortunately, most data shows that most medications used to improve male fertility do not significantly improve sperm parameters, pregnancy, or live birth rates, except for fairly rare specific situations. Similarly, vitamins and supplements have not been proven to improve male fertility or […]
Dr Parviz Kavoussi co-authors study on antisperm antibodies
Antisperm antibodies (ASA) are formed as a result of an abnormal exposure of mature sperm cells to the immune system. ASA testing is a high-level andrology laboratory test that is offered at Westlake IVF for infertile men who meet criteria for this complex testing. Dr. Parviz Kavoussi states, “ASA can be a cause of male […]
Dr. Parviz Kavoussi discusses the impact of COVID 19 infection on male fertility
As the pandemic has continued to impact more people getting infected with COVID 19, more data has been evaluated on the effect of the virus in different areas of health. Dr. Parviz Kavoussi was interviewed on CBS news regarding a new study published in Fertility & Sterility assessing COVID 19 infection impact on male fertility. […]
Dr. Parviz Kavoussi co-authors study on sperm vitality
Sperm vitality is a laboratory assessment of whether sperm cells are alive or not. It is an important adjunct to be considered when basic semen analyses reveal specific concerning findings. Dr. Parviz Kavoussi was part of an international consortium to write a comprehensive scientific article on the diagnosis and management of men with poor sperm […]
Dr. Parviz Kavoussi’s study indicates that men converting from clomiphene to Natesto desiring maintenance of spermatogenesis should be followed closely
A longstanding dilemma in male reproductive medicine has been the treatment of low testosterone in men desiring to maintain fertility. As the majority of testosterone replacement options such as gels and injections diminish sperm production, the primary option has traditionally been the off-label use of clomiphene citrate (CC) to increase serum testosterone levels in a […]
Dr. Parviz Kavoussi co-authors study on retrograde ejaculation
Retrograde ejaculation is a disorder that results in a substantial redirection of semen backwards, so to speak, to the bladder, instead of going the correct direction outward through the urethra. There can be a number of causes of retrograde ejaculation such as pelvic/prostate surgery, pelvic radiation, uncontrolled diabetes, multiple sclerosis, retroperitoneal surgery, and certain medications. […]
Dr. Parviz Kavoussi co-authors study on leukocytospermia
Leukocytospermia, or an elevation of white blood cells in the semen, is a marker of infection or inflammation in the male reproductive tract. When activated, white blood cells can generate high levels of reactive oxygen species resulting in oxidative stress which has been correlated with poor sperm quality, increased levels of sperm DNA damage (fragmentation), […]
Dr. Parviz Kavoussi named Texas Monthly Super Doctor for 11th consecutive year
A select group of physicians in each specialty are selected as a Texas Monthly Magazine Super Doctor. This honor is awarded based on ranking by peers based on surveys, research, and blue ribbon panel review. Dr. Parviz Kavoussi has been named as a super doctor for the 11th consecutive year.
Dr Parviz Kavoussi provides commentary on data confirming COVID 19 mRNA vaccines not harmful for male fertility
With undue concern about the COVID 19 mRNA vaccines (Pfizer, Moderna) having an adverse impact on male fertility, due primarily to social media misinformation, data was needed to disprove this. A study out of the University of Miami was published in JAMA revealing no worsening of semen parameters after receiving the vaccine. Dr. Parviz Kavoussi […]
