The Ins and Outs of Male Fertility Kits

A man’s sperm count. One of the most misunderstood tests in all of medicine. Like naming stars in the sky to help order the universe, we assign “normal” ranges to the features of semen because we can. Unfortunately, except when there are no sperm in the semen (azoopermia) its power to predict male fertility is […]

The Testosterone Tipping Point

Your car is not running well. It just doesn’t have the pick up it used to have. It’s low on gas so you fill it up, but it runs the same. OK, so it’s not the gas…it must be something else, so you begin looking for other causes. Yes, I’m an “old car guy,” but […]

Your Hair, HRT & the Male Reproductive System

This magic pill is finasteride (trade names; Propecia, Proscar, Avodart). It represents a class of drug called the 5-alpha reductase inhibitors.

The Wall of Holiday Cards

I always tell grateful patients that the kindest thing that they can do for me is to send a holiday picture of the family. We have a wall in the clinic that is dedicated to this once a year event. Well, you have outdone yourselves this year! The wall is full of cards and The […]

Why Urology?

I am a men’s health specialist, but I started out as a Why Urology? Admittedly, urology is a small, unusual and low-key medical specialty. In fact, for the longest time, my parents didn’t know exactly what I did as a doctor. I kind of like that about it. Feel free to choose a more glamorous, […]
