It's been established that men with chronic obstructive pulmonary disease (COPD) have reduced levels of endogenous testosterone, but the relationship between pulmonary function and endogenous T levels is inconsistent. Realizing that testicular volume is a known indicator of endogenous testosterone levels, male fertility, and male potency, Korean investigators recently published a study that concluded that testicular volume is - independently - associated with lung/pulmonary function.
Results
Subjects were divided into two groups: those with testicular volume less than 35 mL and those with testicular volume greater than 35 mL. Those in the larger testes group had better lung function (forced vital capacity, forced expiratory volume). The doctors suggested that androgens, at least in men, contribute to better lung function/pulmonary health.

- One hundred and eighty-one men, age 40-70, hospitalized for urological surgery, took part in the study.
- All participants underwent pulmonary function testing and all had testicular volume measured via orchidometry. An orchidometer (or orchiometer) is a medical instrument used to measure the volume of the testicles. It consists of a string of twelve numbered wooden or plastic beads of increasing size from about 1 to 25 millilitres. The beads are compared with the testicles of the patient, and the volume is read off the bead which matches most closely in size.
- Testosterone levels were drawn in early morning hours.
