Evaluation of a patient-centred, needs-based approach to support shared decision making in contraceptive counselling: the COCO study.

OBJECTIVES: The Contraceptive Counselling (COCO) study tested whether a structured approach to assessing patient needs and expectations improved method choice and satisfaction with the contraceptive decision-making process. METHODS: Physicians and women were invited to complete needs-based contraceptive counselling sessions using a structured questionnaire. Physicians recorded the individual responses online; women evaluated the process using an immediate post-consultation questionnaire and then via a structured online interview 6 months later. RESULTS: A total of 92 gynaecologists and 1176 women participated: 951 women completed the immediate post-consultation survey and 145 took part in the 6 month online evaluation. There was a substantial increase in satisfaction with the current contraceptive method: the number of women reporting they were 'very satisfied' with their contraceptive method increased by 30%. This applied to starters and switchers as well as to women continuing with their previous method. Women were highly satisfied with the structured approach; 95% rated the counselling as 'good' or 'very good' and 'comprehensive and detailed'. CONCLUSION: Using a structured approach to share information tailored to women's needs can help them choose from a broader range of methods and, in some cases, change to a method more suitable to their individual needs, and ultimately increase satisfaction with their choice.

Comparison of Whole Ovary Cryotreatments for Fertility Preservation.

The goal of this study was to compare a traditional slow-freeze method (TF) with an open unidirectional slow freeze cooling system (UF) for whole ovary cryopreservation. Therefore, whole pig ovaries were randomly assigned to (A) fresh control, (B) traditional slow freeze (TF) or (C) unidirectional slow freeze (UF). Ovaries were perfused with 10% DMSO in Krebs-Ringer. For TF, whole ovaries were placed in specimen jars containing 10% DMSO and placed into a specialized container for freezing filled with propan-2-ol. For UF, whole ovaries were placed within a specially designed container containing 10% DMSO and transferred to a specialized freezing machine (CTE 920). Histological evaluation demonstrated intact morphology of follicles in all groups; however, an overall decrease of follicle numbers in TF (46%) and UF (50%) compared to fresh control. Live/dead assay indicated significantly lower populations of live cells in both TF (60%) and UF (58%) compared to fresh tissue (74%). TUNEL assay confirmed a difference in percentage of apoptotic follicles between fresh and TF, but there was no significant difference between fresh and UF. To improve the structural and functional integrity of whole ovaries, further investigation, especially into directional freezing, is needed. Whole ovary cryopreservation could provide opportunities for women facing fertility loss due to chemo- or radiotherapy treatment.

Experts' Opinion on the Prenatal Therapy of Congenital Adrenal Hyperplasia (CAH) Due to 21-Hydroxylase Deficiency - Guideline of DGKED in cooperation with DGGG (S1-Level, AWMF Registry No. 174/013, July 2015).

Purpose: This guideline of the German Society of Pediatric Endocrinology and Diabetology (DGKED) is designed to be experts' opinion on the current concept of prenatal therapy for congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH). Several scientific medical societies have also participated in the guideline. It aims to offer guidance to physicians when they counsel affected families about prenatal therapy. Methods: The experts commissioned by the medical societies developed a consensus in an informal process. The consensus was subsequently confirmed by the steering committees of the respective medical societies. Recommendations: Prenatal CAH therapy is an experimental therapy. We recommend designing and using standardized protocols for the prenatal diagnosis, therapy and long-term follow-up of women and children treated prenatally with dexamethasone. If long-term follow-up is not possible, then prenatal therapy should not be performed.

Extracorporeal perfusion of the swine uterus: effect of human seminal plasma.

The active transport of sperm through the female genital tract is a very important factor in the fertilisation process. There is conflicting evidence as to whether seminal plasma has a positive or a negative effect on reproductive performance regarding the sperm transport in the female genital tract. In this study, we investigated if the perfused swine uterus is an appropriate model to study the effect of human seminal plasma on uterine contractility. It was found that repeated application of human seminal plasma caused a significantly higher rise in pressure and frequency of contractions in perfused swine uteri compared to buffer [a 1.8-fold and 1.5-fold pressure rise (Δt1SP, P = 0.025; Δt2SP, P = 0.004)] after the first and second application of seminal plasma respectively, and even a 2-fold pressure rise after the third application with a statistical significance of P = 0.007. The pressure rise caused by the seminal plasma over the entire period of application was calculated using a mathematical programme and was represented by the integral of the pressure curve over time. This perfusion model as well as the use of pressure-time integrals is suitable for patho-physiological studies of the uterus.

The different phenotypes of polycystic ovary syndrome: no advantages for identifying women with aggravated insulin resistance or impaired lipids.

BACKGROUND: According to the classification of polycystic ovary syndrome (PCOS) published by the Androgen Excess Society (AES), 10 different phenotypes of the condition are possible. The question remains of whether using these phenotypes might enable us to identify women with impaired insulin resistance or an impaired lipid profile among patients with PCOS. MATERIALS AND METHODS: A prospective cohort analysis was performed of 313 women with diagnosed PCOS and 80 control individuals. The screening panel included a physical examination, weight and height measurement, ultrasonography of the ovaries, and hormone, glucose, lipid, and insulin resistance measurements. RESULTS: There were no statistically significant differences in insulin resistance parameters between the different phenotypes. There were no statistically significant differences in body mass index (BMI) in any of the groups, but BMI showed the best correlation with insulin resistance in all women with PCOS and controls. Sex hormone-binding globulin (SHBG) was inversely correlated with insulin resistance in women with PCOS and controls. High-density lipoprotein (HDL) was negatively correlated with insulin resistance, and free testosterone was positively correlated with it, only in women with PCOS. CONCLUSIONS: Using the different phenotypes described in the AES classification shows no advantages for identifying women with aggravated insulin resistance or impaired lipid profile among patients with PCOS.

Body composition and bone mineral density in male-to-female transsexuals during cross-sex hormone therapy using gonadotrophin-releasing hormone agonist.

OBJECTIVE: In transsexual people, cross-sex hormone therapy is an important component of medical treatment and results in a complete change in the sex hormone environment. Steroid hormones plays an important role in developing and maintaining bone mass and body composition in both sexes. The aim of this study was to evaluate changes in body composition and bone mineral density (BMD) during cross-sex hormone therapy in transsexuals using gonadotrophin-releasing hormone agonists and intramuscular oestrogens. METHODS: 84 male-to-female transsexuals (MtFs) were treated with 10 mg oestradiol-17ß valerate every 10 days. The study population was treated with subcutaneous injections of 3.8 mg goserelin acetate every 4 weeks to suppress endogenous sex hormone secretion completely. Endocrine parameters, body composition and BMD after 12 months and after 24 months were compared with baseline values. RESULTS: There was a significant decline in gonadotrophins and testosterone, while oestradiol, sex hormone-binding globulin, and high-density lipoprotein levels increased significantly after 12 and 24 months. There was a significant increase in body mass index (BMI), fat mass, and lumbar spine bone mineral density in MtFs during the study period, while lean mass decreased significantly and no effect was observed on femoral bone mineral density. CONCLUSION: There was an increase in BMI associated with a shift from lean mass to fat mass. There appears to be no risk of osteoporosis developing in MtFs when there is adequate oestrogen substitution, even in the absence of testosterone. Furthermore in comparison with hormone regimes using oral medications, the complication rates appear to be lower in patients receiving gonadotrophin-releasing hormone agonists and intramuscular oestrogens.

Fertility preservation in cancer patients.

Today the vast majority of children and adolescents diagnosed with cancer achieve relatively high rates of remission and long-term survival, due to significant advances in oncological treatment. Oncological surgery, radiotherapy and chemotherapy however, are often detrimental to fertility, thus substantially impacting a patient's quality of life. Concerns about fertility are similar for men and women; however, their opportunities for intervention differ considerably. This article reviews the literature, discusses the etiology and effects of cancer treatment on fertility, and presents the current and emerging options for the preservation of fertility in patients with cancer. The various diagnostic methods of assessing the fertility potential at the time of diagnosis and the efficacy of the different fertility preserving methods after cancer treatment are also presented.

The intrauterine to intra-arterial pressure ratio: a new parameter for the study of uterine contractility physiology.

The objective of the study was to examine the uterine contractions and the arterial perfusion pressure changes after application of oxytocin, endothelin 1, prostaglandins PGE(1), PGE(2) and PGF(2alpha), in order to identify the substance with the greatest intrauterine pressure (IUP)/intra-arterial pressure (IAP) ratio, which means the substance most suitable for inducing uterine contractility without raising the systemic vascular pressure. Increasing doses of oxytocin, endothelin 1, PGE(1), PGE(2) and PGF(2alpha) were applied as bolus injection through the uterine artery of perfused swine uteri and the intrauterine and intra-arterial pressure rises were recorded. All substances showed a significant cervicofundic pressure gradient and, with the exception of PGF(2alpha), the uterine peristalsis moved towards the cervix uteri. The perfusion pressure after application of oxytocin, PGE(1), PGE(2) and PGF(2alpha) reached a maximum value and started to decrease, whereas endothelin 1 caused a continuous increase in the perfusion pressure. Endothelin 1 showed the lowest IUP/IAP ratio and oxytocin the greatest. In conclusion, the IUP/IAP ratio provides a promising new parameter for the study of uterine contractility physiology. Besides oxytocin, PGE(2) and PGF(2alpha) emerged as the best candidate substances to improve uterine contractility without raising the intra-arterial pressure.

The effect of metformin treatment for 2 years without caloric restriction on endocrine and metabolic parameters in women with polycystic ovary syndrome.

INTRODUCTION: The aim of this study was to evaluate long-term changes in endocrine and metabolic parameters and body mass index in women with polycystic ovary syndrome (PCOS) who were treated with metformin over 2 years without caloric restriction. MATERIAL AND METHODS: Twenty-six obese women with PCOS were treated with metformin over 2 years without caloric restriction. Clinical, metabolic and endocrine parameters and the body mass index were measured and an oral glucose tolerance test was carried out to calculate insulin resistance indices at the beginning and at the follow-up after 2 years. The Homeostatic Model for Assessment of Insulin Resistance (HOMA-IR) was calculated. RESULTS: No significant changes in body mass index or HOMA-IR were observed. However, a significant decrease in fasting and 2-h insulin levels was observed. Women showed a significant increase in sex hormone-binding globulin (SHBG) levels, while total testosterone (TT) levels and the free androgen index decreased significantly. Furthermore a significant decrease in hirsutism was observed. There was a decrease in cholesterol and an increase in high-density lipoprotein. CONCLUSIONS: Long-term treatment with metformin in women with PCOS appears to reduce androgen excess due to increased SHBG and decreased TT levels resulting in improvement of hirsutism as a clinical sign of androgen excess. Furthermore a significant decrease in fasting and 2-h insulin levels and slightly improved insulin resistance indices were observed.

Thyroid-stimulating hormone is associated with insulin resistance independently of body mass index and age in women with polycystic ovary syndrome.

BACKGROUND: The aim of this study was to evaluate the association between thyroid function, reflected by thyroid-stimulating hormone (TSH) levels, and insulin resistance (IR) in 337 women suffering from polycystic ovary syndrome (PCOS). METHODS: Clinical, metabolic and endocrine parameters were obtained and an oral glucose tolerance test was performed, with calculation of IR indices. The association between thyroid function and IR was evaluated with classification analysis using logistic regression and 10-fold cross-validation to identify a possible TSH threshold for IR. Parameters were then compared between women above and below the TSH threshold using two-sample tests. One-way analyses of covariance were performed to explore whether the impact of TSH on IR is independent of other variables. RESULTS: A TSH cut-off value around 2 mIU/l had the best sensitivity and specificity for identifying women with IR. Women with TSH >or= 2 mIU/l were younger, had a higher body mass index (BMI) and were more insulin-resistant compared with women with TSH < 2 mIU/l. This effect of TSH on IR was independent of age and BMI. CONCLUSIONS: In women with PCOS, a significant association between thyroid function, as reflected by TSH >or= 2 mIU/l, and IR was found and the association appeared to be independent of age and BMI.
