Creating a Global Community of Practice for Oncofertility.

Fertility preservation in the cancer setting, known as oncofertility, is a field that requires cross-disciplinary interaction between physicians, basic scientists, clinical researchers, ethicists, lawyers, educators, and religious leaders. Funded by the National Institutes of Health, the Oncofertility Consortium (OC) was formed to be a scientifically grounded, transparent, and altruistic resource, both intellectual and monetary, for building this new field of practice capable of addressing the unique needs of young patients with cancer. The OC has expanded its attention to include other nonmalignant conditions that can threaten fertility, and the work of the OC now extends around the globe, involving partners who together have created a community of shared effort, resources, and practices.

Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe.

Purpose: Oncofertility focuses on providing fertility and endocrine-sparing options to patients who undergo life-preserving but gonadotoxic cancer treatment. The resources needed to meet patient demand often are fragmented along disciplinary lines. We quantify assets and gaps in oncofertility care on a global scale.

Survey of Third-Party Parenting Options Associated With Fertility Preservation Available to Patients With Cancer Around the Globe.

Purpose: In the accompanying article, "Survey of Fertility Preservation Options Available to Patients With Cancer Around the Globe," we showed that specific fertility preservation services may not be offered at various sites around the world because of cultural and legal barriers. We assessed global and regional experiences as well as the legal status of third-party reproduction and adoption to serve as a comprehensive international data set and resource for groups that wish to begin oncofertility interventions.

Methods: We provide data on the legalities of third-party assisted reproductive technologies and other family-building options in the 28 oncofertility-practicing countries surveyed.

Purpose: To investigate the effects of various progestins in combined oral contraceptives (COCs) on lamotrigine (LTG) serum concentrations and, vice versa, the potential impact of LTG on progestin serum levels during the menstrual cycle.

Methods: Twenty women with epilepsy (WWE) undergoing LTG monotherapy and COC (LTG group; mean ± SD [median; range] age 24.2 ± 4.

Opioids and reproduction.

More than 40years ago, the endogenous opioids were first described. Their role as important neuromodulators of pain and their influence on a variety of neuroendocrine control systems within the central nervous system has been recognized. More recently, endogenous opioids and their receptor have been identified in a variety of reproductive and non-reproductive tissues outside the central nervous system.

Behavioural and neural responses to aversive visceral stimuli in women with primary dysmenorrhoea.

Background: Chronic pelvic pain, in particular dysmenorrhoea, is a significant yet unresolved healthcare problem in gynaecology. As interoceptive sensitivity and underlying neural mechanisms remain incompletely understood, this functional magnetic resonance imaging (fMRI) study assessed behavioural and neural responses to visceral stimuli in primary dysmenorrhoea (PMD).

Methods: Women with PMD (N = 19) without psychological comorbidity and healthy women (N = 20) were compared with respect to visceral sensory and pain thresholds, and to neural responses to individually calibrated mildly painful and painful rectal distensions implemented during scanning.

Fertility Preservation for Patients with Malignant Disease. Guideline of the DGGG, DGU and DGRM (S2k-Level, AWMF Registry No. 015/082, November 2017) - Recommendations and Statements for Girls and Women.

Aim: The aim of this official guideline published by the German Society of Gynecology and Obstetrics (DGGG) and coordinated with the German Society of Urology (DGU) and the German Society of Reproductive Medicine (DGRM) is to provide consensus-based recommendations, obtained by evaluating the relevant literature, on counseling and fertility preservation for prepubertal girls and boys as well as patients of reproductive age. Statements and recommendations for girls and women are presented below. Statements or recommendations for boys and men are not the focus of this guideline.

Beta endorphin in serum and follicular fluid of PCOS- and non-PCOS women.

Purpose: To compare the concentrations of beta endorphin in serum and follicular fluid (FF) of PCOS- and non-PCOS women. Secondarily, to investigate associations between beta endorphin and other parameters.

Methods: Fifty-nine women undergoing in vitro fertilization (IVF) were included in the study.

Impact of the opioid system on the reproductive axis.

Endogenous opioids, first described more than 40 years ago, have long been recognized for their main role as important neuromodulators within the central nervous system. More recently endogenous opioids and their receptor have been identified in a variety of reproductive and nonreproductive tissues outside the central nervous system. Their role within these tissues and organs, however, is only incompletely understood.

What is new in 2017? Update on fertility preservation in cancer patients.

The prevention of fertility loss due to cancer treatment as well as non-malignant causes has been gaining importance over the last few decades. Clinically applied modalities for fertility preservation in cancer patients include cryopreservation of oocytes and embryos, the application of GnRH agonists, ovarian tissue banking, and cryopreservation of ejaculated or surgically extracted sperm. In addition, several new possibilities to restore fertility are currently being investigated, such as the establishment of in-vitro culture systems for gonadal tissue, the development of artificial gonads, and the application of germline stem cells.

Localization of TrkB and p75 receptors in peritoneal and deep infiltrating endometriosis: an immunohistochemical study.

Background: The roles of the neurotrophins NGF (Neurotrophic growth factor) and BDNF (brain-derived neurotrophic factor) in neuronal growth and development are already known. Meanwhile, the neurotrophin receptors TrkA (tropomyosin related kinase A), TrkB, and p75 are important for determining the fate of cells. In endometriosis, this complex system has not been fully elucidated yet.

Follicular growth after xenotransplantation of cryopreserved/thawed human ovarian tissue in SCID mice: dynamics and molecular aspects.

Purpose: To study the influence of xenotransplantation on follicular recruitment and growth in cryopreserved/thawed human ovarian tissue.

Method: Two 3-mm pieces of cryopreserved/thawed human ovarian tissue obtained from female cancer patients (n = 11) were xenotransplanted into a subcutaneous neck pouch of 6-week-old ovarectomized SCID mice (n = 33) for 4 (n = 18) and 12 (n = 15) weeks.

Result: Thirty-two out of 33 mice survived the entire observation periods.

Opiate receptor blockade on human granulosa cells inhibits VEGF release.

The objectives of this study were to determine whether the main opioid receptor (OPRM1) is present on human granulosa cells and if exogenous opiates and their antagonists can influence granulosa cell vascular endothelial growth factor (VEGF) production via OPRM1. Granulosa cells were isolated from women undergoing oocyte retrieval for IVF. Complementary to the primary cells, experiments were conducted using COV434, a well-characterized human granulosa cell line.

Metformin induces a prompt decrease in LH-stimulated testosterone response in women with PCOS independent of its insulin-sensitizing effects.

Background: The use of insulin-sensitizing drugs has been shown to improve both the reproductive and the metabolic aspects of PCOS. However, the mechanisms by which metformin exerts its effects in PCOS are still not completely understood. There is growing evidence of a direct effect of metformin on ovarian steroidogenesis, independent of its effects on insulin sensitivity.

Afamin serum concentrations are associated with insulin resistance and metabolic syndrome in polycystic ovary syndrome.

Background: High plasma concentrations of the vitamin E-binding protein afamin have been previously shown to be associated with insulin resistance and metabolic syndrome. We set out to determine whether the concentration of afamin in the serum of women with polycystic ovarian syndrome (PCOS) is elevated in relation to the presence and severity of insulin resistance (IR).

Methods: This cross-sectional study looked at 53 patients with PCOS and 49 non-PCOS patients.
