"My patient was a testis cancer survivor. After living through surgery and chemotherapy, he now enjoys and savors every breath he takes. The reason he was in front of me was that he wanted children but was found to have no ejaculated sperm. Azoospermia, a sobering consequence of cancer or its treatment.

He was seen back East by several infertility specialists and they all recommended the same procedure: Microdissection testicular sperm extraction (Micro-TESE) in conjunction with IVF and single sperm injection. But the patient said to me: “Doc, I gotta protect this little guy as it's the only one that I have left. This ‘big dig' for sperm just doesn't sit right with me.”

Testicle Friendly

I offered him a more user-friendly alternative: Sperm Mapping. An office procedure done with fine needles in an hour or so, Sperm Mapping is also well established and can find testicular sperm in small places. The essential difference between Mapping and micro-TESE is that Mapping is a far less invasive way to figure out if there are sperm in the testicles, as no large incisions are made in somewhat sensitive places. This he found attractive. But after I explained some other advantages of Mapping, it sealed the deal for this judicious guardian of his jewels:"

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
