Current and Future Medical Therapies for Adenomyosis

SEMINARS IN REPRODUCTIVE MEDICINE

Authors: Cope, Adela G.; Ainsworth, Alessandra J.; Stewart, Elizabeth A.

There is no approved medical therapy for adenomyosis and limited evidence to guide treatments in part due to the complexity of nonhistologic diagnosis and the prevalence of concomitant gynecologic conditions. Most available evidence focuses on the treatment of heavy menstrual bleeding, painful menses, and pelvic pain. Data evaluating fertility outcomes, sexual function, and quality of life following treatment are lacking. Additionally, there is no disease-specific measure of quality of life for adenomyosis. The levonorgestrel-releasing intrauterine system appears to be the most effective first-line therapy based on efficacy compared with oral agents, maintenance of steady-state hormonal levels, and contraceptive benefit. In areas where it is marketed, the progestin dienogest appears superior to combined oral contraceptives. Long-acting gonadotropin-releasing hormone agonists are effective and should be considered second-line therapy but are limited by hypogonadal effects. Additional data regarding oral gonadotropin-releasing hormone antagonists are required. While aromatase inhibitors demonstrate improvement in heavy menstrual bleeding and pelvic pain, further research is needed to determine their role in the management of adenomyosis. Progesterone receptor modulators may have a role for this disease if released again to market with appropriate safety parameters. Finally, modulation of prolactin and/or oxytocin may provide novel nonsteroidal treatment options.

Influence of sex, menstrual cycle, and hormonal contraceptives on egocentric navigation with or without landmarks

PSYCHONEUROENDOCRINOLOGY

Authors: Bernal, A.; Mateo-Martinez, R.; Paolieri, D.

This study examines the influence of sex, menstrual cycle, hormonal contraceptives (HC) and sex hormone levels in following egocentric navigation instructions with or without landmarks. Estradiol seem to bias the reference frame for navigation during estrous cycle of female rats. However, previous studies in humans found no differences in overall navigation between women in their early follicular and mid-luteal menstrual cycle phases, whose performance was worse than that of men. Our study hypothesis was that the performance of women would be improved during the peri-ovulatory phase and would remain the same during placebo and active phases of HC users. The study included 21 men, 62 women with natural menstrual cycle (21 during early follicular phase, 20 during peri-ovulatory phase, and 21 during mid-luteal phase), and 38 women that were receiving HC (13 during placebo phase and 25 during active phase). The men outperformed the women with a natural menstrual cycle when following egocentric instructions without landmarks. However, the women's performance varied according to the phase of their menstrual cycle, differing from men during early follicular and mid-luteal phases but not during the peri-ovulatory phase. The use of HC also improved the performance of women to the extent that the difference with men disappeared. No differences were observed between HC-placebo and HC-active user groups during egocentric navigation without landmarks and among all groups during egocentric navigation with landmarks. Analysis of salivary hormones showed that testosterone levels were higher in men and that estradiol levels in women were higher during peri-ovulatory and mid-luteal phases and also in HC users. Progesterone levels were higher in women during the mid-luteal phase. These results appear compatible with beneficial effect of testosterone and estradiol on egocentric navigation without landmarks and with a block of this effect produced by progesterone.
