MALE LOW LIBIDO

MALE LOW LIBIDO AND ESTROGENS
Desire (male libido
and female libido ) consists of fantasies and a desire to have
sexual activity, experienced both at the mental/emotional level and as a
physical/somatic hunger for sex. Principally driven by testosterone in both
male and female, genitally focused, sexual thoughts/desires must be present to initiate
our sexual cycle. Estrogens in both women and men are important
for human sexual interaction emphasizing touch, physical closeness, receptivity,
love and nurturance. Arousal is the developing subjective sense of increasing
sexual pleasure accompanied by physiological excitement.
MALE LOW LIBIDO AND THE
IMPORTANCE OF TESTOSTERONE LEVELS:
Critical to
low male libido and genitally focused sexuality, as well as overall well
being, bone growth, improved affect, increased skeletal muscle power and
activity, and a general sense of well being. Testosterone blood levels are
generally misinterpreted by physicians. Laboratory values reflect a normal bell
curve of distribution, but not a sexual function normal range. Males below
350-ng/dl total testosterone, and arguably 400ng/dl, will experience decreased
libido, difficulty in obtaining or sustaining an erection, and problems
ejaculating. Orgasmic intensity at the lower levels is often diminished.
Therapeutic replacement to measured levels of total testosterone in the 800 –
1200 ng/dl range is clinically beneficial, especially in treating sexual
dysfunctions in the older male. Sex hormone binding globulin (SHBG) increases
with aging in men so that the availability of free testosterone, the
functionally active form, diminishes with age resulting in male low
testosterone. I obtain total and free
testosterone levels in patients. I occasionally encounter adequate total
testosterone with inadequate free testosterone levels, which is a treatable
situation.
