Research highlights

Small nerve fibres detected in the functional layer in all women with endometriosis may have important implications for understanding the generation of pain in these patients. The presence of nerve fibres in an endometrial biopsy may be a novel surrogate marker of clinical endometriosis.

A Cochrane review has found that endometriosis patients who use gonadotropin-releasing hormone (GnRH) agonists in the run-up to IVF have improved outcomes.

The proliferative activity of early ovarian clear cell adenocarcinoma seems to depend on the association of this cancer with endometriosis. When endometriosis is associated with ovarian clear cell adenocarcinoma, there is a change of its cytokine production that may inhibit tumour growth.

Expression of class I human leukocyte antigen (HLA I) is significantly higher in endometrial samples from patients with endometriosis than in those from other people.
Vernet-Tomas del M, Perez-Ares CT, Verdu N, Molinero JL, Fernandez-Figueras MT, Carreras R. The endometria of patients with endometriosis show higher expression of class I human leukocyte antigen than the endometria of healthy women. Fertility and Sterility 2006; 85: 78-83.

Women with a specific type of uterine anomaly appear to be at high risk of endometriosis, even though their menstrual flow is not obstructed, researchers report.
Nawroth F, Nawroth F, Rahimi G, Nawroth C, Foth D, Ludwig M, Schmidt T. Is there an association between septate uterus and endometriosis? Hum Reprod. 2006; 21(2): 542-4.

A low-dose norethindrone acetate could be considered an effective, tolerable, and inexpensive first-choice medical alternative to repeat surgery for treating symptomatic rectovaginal endometrioti lesions in patients who do not seek conception.
Vercellini P. Pietropaolo G, De Giorgi O, Pasin R, Chiodini A, Crosginani PG. Treatment of symptomatic rectovaginal endometriosis with an estrogen-progestogen combination versus low-dose norethindrone acetate. Fertil Steril 2005; 84(5):1375-87.
