Excellent Video by Dr. Ramasamy and his group detailing Onco MicroTESE technique at their institution.

Keep up the great work Micah!

This has been a point of debate between male infertility specialists and REI groups. When the pedal for IVF/ICSI is being pushed hard by the REI groups in these patients, we need to take a step back and consider what is best for our patients. Unless the female partner is older, this meta analysis supports slowing things down and repairing the varicocele to optimize the environment in which sperm is being produced and maybe increase the chance for IVF/ICSI success. Great article! I will definitely pass this along to our REI group.

Thank you to the brave men and women who have volunteered to put themselves in harm's way to protect our freedoms. I do see some of these young men after they are stabilized from their initial injuries and then discharged from the military at our local VA hospital. It is devastating to me that we have good options to obtain sperm for IVF/ICSI but unfortunately the price point is oftentimes too high for the couple to afford. Because this is not a covered VA benefit, we do not offer it at that specific facility. In men that have complete destruction of their genitalia, it is reassuring to know that SV aspiration can be considered, although this study did have very small numbers. For the urologists that routinely perform transrectal US and prostate biopsies, this will come very easily and should be considered a part of the sperm retrieval armamentarium. With the recent announcement that the government may start covering for cryopreservation of sperm and eggs, hopefully we won't have to worry about difficult retrievals.

I think this device has a lot of potential to enhance care not only for our male infertility patients but also for our urology patients s/p vasectomy or vasectomy reversal. Microscopes are expensive to purchase but this $7 attachment to a smartphone makes it easy to answer the question of whether there is sperm in the ejaculate or not. With the correlations to CASA, a sensitivity nearing 86% and specificity nearing 91%, this device, although not perfect and probably won't replace the andrology lab, has a lot of potential to improve point of care delivery for our patients. I can't wait to try out this device myself.

Sperm has been the primary focus of our field, but this study demonstrates the importance the carrier fluid in which the sperm is transported. Very interesting findings. Along the same line of Dr. Samplaski's thoughts, I then wonder how antisperm antibodies interact and impact the vaginal/uterine environment. Seminal fluid manipulation may be an area in which research could be done to see if the optimal fertilization environment can be reached in a couple's infertility treatment.
