 When it comes to testosterone replacement, it seems to be a man's world. But did you know that testosterone is just as important for women as it is for men? Hi, I'm Dr. Lawrence Hatchett, a Harvard-trained urologist specializing in hormone replacement for both men and women. The common theme I hear is patients complaining of exhaustion, depression, weight gain, hot flashes, and yes, loss of sexual desire. All symptoms of low testosterone.
