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 […]

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 […]

Dr. Parviz Kavoussi is featured on Lifetime’s Balancing Act discussing treatment of testosterone deficiency in a fertility preserving manner

One of the long-standing challenges in men with testosterone deficiency has been treatment for this condition in a manner that does not suppress sperm production but also optimizes symptomatic response to treatment.  Traditional testosterone replacement treatments, such as gels and intramuscular injections, significantly suppress sperm production.  This has left limited treatment options for men […]
