Dyspareunia: Surgery and Low-Dose Progestin Both Effective

Surgery and low-dose progestin are similarly effective against endometriosis-associated severe deep dyspareunia, but the timing of their effects differs, according to the findings of a patient-preference, parallel cohort study.
Paolo Vercellini, MD, from Università Statale di Milano and the Fondazione IRCCS 'Ca' Grandà–Ospedale Maggiore Policlinico in Milan, Italy, and colleagues present their findings in an articlepublished online February 26 and in the May issue of Human Reproduction.
"Painful sex also has personal and intimate implications, including substantial psychological and relational distress, as well as unfavourable emotional impact in partners," the authors write. "However, only limited information is available on the consequences of endometriosis-associated deep dyspareunia, as well as of the effect of medical and surgical treatment alternatives for this condition, in terms of variations in sexual functioning, psychological status and health-related quality of life."
Therefore, the authors recruited 18- to 40-year-old nonpregnant women who had previously undergone laparoscopy or laparotomy for stage 3/4 endometriosis in the previous 2 years and allowed them to select surgical or low-dose norethisterone acetate (NETA) treatment.
Among 51 women who underwent surgery and 103 women who selected NETA treatment, higher Female Sexual Function Index overall scores and subdomain scores were noted in the surgery group after 3 months, but the differences dissipated by 12 months, excluding the higher scores for lubrication, desire, and arousal in the surgery group.
However, significant differences from baseline were observed in the overall scores in both the surgery (P< .0001) and NETA (P = .002) groups.
The exclusion criteria included obstructive uropathy or bowel stenosis, typical contraindications to progestins, and an unwillingness to tolerate menstrual changes; the authors performed regression analysis adjusted for age, sex, body mass index, and other variables.
Similar to what was observed for Female Sexual Function Index scores, the Hospital Anxiety Depression Scale overall and subdomain scores were higher in the surgery group after 3 months, but these differences did not persist at 12 months. The overall and subdomain Hospital Anxiety Depression Scale scores were significantly lower after 12 months compared with baseline in both groups (P ≤ .0001).
For the Endometrial Health Profile-30 scores, the NETA group had significantly (P < .05) worse scores for the subdomains of pain, control and powerlessness, and medical profession. The surgery group had significantly higher Endometrial Health Profile-30 scores for the subdomains of emotional well-being, social support, self image, sexual intercourse, and infertility at 3 months, whereas significant differences in favor of the NETA group were observed for pain, control and powerlessness, relationship with children, work, and medical profession at 12 months.
The limitations of the study included a lack of randomization, selection bias, and an imbalance in the study groups.
"In conclusion, surgery and low-dose oral NETA demonstrated a similar final beneficial outcome in women with endometriosis-associated deep dyspareunia in terms of improvement of sexual functioning, psychological well-being and health-related quality of life at 1-year follow-up," the authors write. "[I]n light of the observed differences in the temporal pattern of the effect, further comparative studies with longer follow-up are warranted."
