Objectives:
The aim was to evaluate the therapeutic effects of dehydroepiandrosterone (DHEA) and DT56a (Femarelle®) on systemic and genitourinary symptoms of menopause in postmenopausal women.
Design:
A comparative effectiveness research study of seventy postmenopausal women (mean age: 53 years), experiencing postmenopausal symptoms, was designed.
Participants:
Seventy patients were randomly assigned to receive either DHEA (60 mg/day) or Femarelle® (644 mg/day) for 3 months.
Materials, Setting, Methods:
Subjects were assessed for serum estradiol, luteinizing hormone, follicle-stimulating hormone, Greene Climacteric Scales Scores, female urinary symptoms, and female sexual function index (FSFI).
Results:
Both DHEA and Femarelle® demonstrated comparable efficacy in reducing total Greene Climacteric Scale scores. No significant differences in serum follicle-stimulating hormone and E2 levels were observed between the 2 groups. Within-group analyses showed that DHEA was associated with significant improvements in urinary symptoms (overactive bladder symptom score, urinary distress inventory-6, incontinence impact questionnaire-7, international consultation of incontinence questionnaire, and pelvic organ prolapse distress inventory) and sexual function measures (FSFI domains including desire, arousal, lubrication, orgasm, and satisfaction), whereas Femarelle® did not show significant changes over the 3-month period. Between-group comparisons of change scores suggested a trend toward greater improvement in the DHEA group; however, these findings should be interpreted with caution, given the exploratory design and limited sample size.
Limitations:
The absence of testosterone measurements limits the assessment of the androgenic effects of DHEA. Femarelle® has never been studied for sexual function; our findings are preliminary and require long-term validation.
Conclusions:
While both DHEA and Femarelle® were effective in improving climacteric symptoms, DHEA was associated with improvements in genitourinary symptoms in this cohort. However, given the exploratory design and absence of a placebo control, these findings should be interpreted as hypothesis-generating.

Menopause
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.
Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Gonadal and Placental Hormones
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...
