Exploring Low-Dose Tadalafil for Women's Sexual Health

Impairment of couple relationship in male patients with sexual dysfunction is associated with overt hypogonadism. Tadalafil (Cialis) is used to treat erectile dysfunction (ED, impotence; inability to get or keep an erection), and the symptoms of benign prostatic hyperplasia (BPH; an enlarged prostate) which include difficulty urinating (hesitation, dribbling, weak stream, and incomplete bladder emptying), painful urination, and urinary frequency and urgency in adult men.

How should this medicine be used?

As all of these symptoms could be associated with hypogonadism, we have investigated the possible relationship between androgen levels and an unhappy couple relationship. A consecutive series of 2,302 (mean age 53.2 ± 12.5 years) male patients with ED was studied. Several hormonal parameters were investigated, along with penile Doppler ultrasound (PDU) and the Structured Interview on Erectile Dysfunction (SIEDY) and ANDROTEST. Higher ANDROTEST score identifies a higher prevalence of hypogonadism-related symptoms and signs. SIEDY Scale 2 score was associated with decreased intercourse frequency, severe ED, lower dynamic peak systolic velocity at PDU, and clinical (ANDROTEST score) and biochemical (low total and free testosterone) hypogonadism, even after adjusting for cofounders, such as patient's and tadalafil for premature ejaculation partner's age, waist circumference, and smoking habit. Tadalafil (Adcirca) is used to improve the ability to exercise in people with pulmonary arterial hypertension (PAH; high blood pressure in the vessels carrying blood to the lungs, causing shortness of breath, dizziness, and tiredness).

Tadalafil is in a class of medications called phosphodiesterase (PDE) inhibitors. It works to treat erectile dysfunction by increasing blood flow to the penis during sexual stimulation. This increased blood flow can cause an erection. Tadalafil treats PAH by relaxing the blood vessels in the lungs to allow blood to flow more easily.

Understanding Female Sexual Dysfunction (FSD)

Limitations of this study include inconsistencies in tadalafil dosing and bosentan background therapy. In addition, information on hormone replacement therapy and hormone-based contraceptive use in this patient cohort was not available. The assumption of menopausal status was based on age, and no actual information on patients’ menopausal status was available at the time of this study. The use of 6MWD as a primary end point and the short duration of the PHIRST study also present potential limitations. 6MWD should be viewed as an intermediate end point; further research into the impact of sex and menopausal status on the effects of PDE-5 inhibitors on mortality and morbidity is required.31,32 In conclusion, while PAH is a disorder with a known female and postmenopausal predominance, it appears that males and premenopausal females may experience greater functional improvement when treated with tadalafil than older women.

No consistent effect of sex or menopause on TCW was observed. All subjects regardless of sex or age demonstrated improvement with tadalafil compared with placebo. These additional findings with regard to sex and estimated menopausal status provide clinicians with further information that can be used to individualize treatment for patients.

Alternative models were explored using these different factors as dependent variables in order to evaluate the specific relationship among the parameters studied. Multiple logistic regression analysis indicated that low penile blood flow and decreased intercourse frequency are bi-directionally coupled to poor relational domain, while the association with hypogonadism was mediated through sexual hypoactivity or inertia. Our data suggest that, in subjects consulting for sexual dysfunction, a deterioration of the couple's relationship is associated with impairment in sexual activities, which, in turn, can lead to a mild hypogonadism. Any speculation on pathogenetic relationships should be confirmed through prospective studies or intervention trials.
