RESUMO

Menstrual irregularities are one of the main clinical symptoms caused by polycystic ovary syndrome (PCOS). Pharmacological treatment options for non-fertility indications to restore menstrual frequency play an important role in the management of PCOS. Oral contraceptive pills are commonly prescribed for adolescents with menstrual irregularities, however, when contraindicated or poorly tolerated, further pharmacological therapy is required. This systematic literature research aims to provide an overview concerning the effects of non-hormonal pharmacological treatment options on menstrual irregularities in adolescents suffering from PCOS. A systematic literature search in PubMed, Cochrane, Embase, Bio-SISS and Web of Science was performed, including literature from January 1998 to September 2022, using specific keywords in order to find related studies. n = 265 studies were identified of which n = 164 were eligible for further evaluation. Only four placebo-controlled studies were identified, with diverging inclusion and exclusion criteria. Available data on specific non-hormonal off-label use medication primarily consisted of metformin, Glucagon-like peptide 1 receptor agonists, thiazolidinediones, anti-androgen agents (spironolactone, finasteride, flutamide) and supplements (chromium picolinate, myo-inositol). However, only a few have partly pointed out beneficial effects on improving menstrual frequency in patients diagnosed with PCOS. In summary, metformin in dosages of 1500-2550 g/day, GLP-1-analogues and supplements were effective in regulation of menstrual cycles in adolescents diagnosed with PCOS. Menstrual frequency in adolescents with PCOS is essential to prevent hypoestrogenism with long-term consequences. In this context, MET is the most effective and cost- efficient in overweight adolescent girls, also showing beneficial effects in the regulation of insulin sensitivity, especially if COCs are contraindicated or not well-tolerated. Further studies are needed to evaluate therapies in lean and normal-weight girls with PCOS.

RESUMO

The goal of this study was to explore the experience and perception of men during the diagnosis of infertility and subsequent treatment, and the impact on role concepts, control beliefs, and quality of life on these processes. Furthermore, it aimed to derive improvements in how men should be counselled. A qualitative study was conducted. It consisted of 13 semi-structured individual interviews with men undergoing or about to start fertility treatment at Heidelberg University Hospital. Data were analyzed using a grounded theory approach. Men emphasized the rare opportunities for being involved in treatment, lack of control and the ambivalence of social support. Furthermore, their experiences differed enormously regarding the cause of infertility and the period for which they were preoccupied with the topic. Dealing with involuntary childlessness is challenging for all men. Nevertheless, participants revealed major differences in dealing with fertility treatment in relation to role concepts, control beliefs, social support and the cause of infertility. The significance of diverse causes of infertility and the need for men to adopt certain roles ought to be more valued and a holistic approach improving quality of life enhanced.

RESUMO

INTRODUCTION: During pregnancy, physiologic changes in maternal thyroid function take place especially due to hormonal as well as metabolic processes. Human chorionic gonadotropin activates the maternal thyroid gland leading to increased thyroid hormone production. A sufficient availability of maternal thyroid hormones is essential for fetal development, especially during the first trimester of pregnancy, when the fetal thyroid gland is not yet functional. MATERIALS AND METHODS: Current knowledge of thyroid dysfunction including thyroid autoimmunity, hypothyroidism or hyperthyroidism is summarized with special focus on miscarriage and pregnancy disorders. Therefore, a Medline research as well as an analysis of current guidelines on thyroid function and pregnancy was performed. RESULTS: A study focusing on TSH levels in normal and disturbed pregnancies, the risk of miscarriage in association with thyroid autoantibodies, and (subclinical) hypothyroidism in infertile and fertile women were included. CONCLUSION: Maternal thyroid dysfunction negatively affects pregnancy outcome. Besides a routine iodine supplementation in pregnant women and treatment of hypo as well as hyperthyroidism, TSH levels should routinely be measured in women during childbearing years and adjusted to concentrations <2.5 mIU/l in order to optimize maternal health and fetal development.

RESUMO

OBJECTIVE: Phytoestrogens are a diverse group of nonsteroidal plant compounds that occur naturally in many plants. Because they possess a ring system similar to estrogens they are able to bind on estrogen receptors alpha and beta in humans. The effects of the phytoestrogens genistein and daidzein on the production of progesterone and estrogen in isolated human term trophoblast cells in vitro were tested in this study. MATERIAL AND METHODS: Cytotrophoblast cells were isolated from human term placentas. Phytoestrogens genistein and daidzein were incubated in different concentrations with trophoblast cells. Untreated cells were used as controls. After 24 h aliquots were removed and tested for progesterone and estrogen production. RESULTS: The production of the steroid hormones progesterone and estrogen are influenced by phytoestrogens genistein and daidzein in human term trophoblast cells. A strong inhibition effect of both phytoestrogens tested in the production of progesterone was demonstrated. In addition, a significant stimulating effect on estrogen production by genistein and daidzein was observed. CONCLUSION: Results obtained with this study show that phytoestrogens (genistein and daidzein) sufficiently reduce progesterone production in human term trophoblast cells. Because blockade of progesterone is a possible mechanism involved in initiation of labor, we may speculate that high doses of phytoestrogens at the feto-maternal interphase could play a negative role in maintenance of pregnancy. Stimulation of estrogen production by genistein and daidzein in trophoblast cells is probably due to estrogen receptor blocking effects of both phytoestrogens. Trophoblast cells seem to compensate blocking of its estrogen receptors by higher estrogen production.
