Selenium Supplements

Background: Selenium is a micronutrient, although required in low amounts, its importance in male and female reproduction is well known. Objectives: The core purpose of this study is to evaluate the role of selenium in human reproduction, during pregnancy/ lactation in women and newborns. The review explains side by side the sources of selenium, required amounts of selenium in humans and during pregnancy or lactation. Methods: Selenium deficiency is a major cause of male infertility. Similarly, selenium deficiency, both in pregnant and postpartum women, would greatly affect the health of the newborn baby in all respects. The effect of maternal selenium upon the fetus and the neonates even one year after birth has been explained with some recent examples. Results: The study elaborates the fact that the selenium deficiency in pregnancy and lactation is common due to fetal/infant development, so selenium supplements must be provided in order to overcome these deficiency symptoms. Conclusions: The better reproductive health in humans is possible due to the sufficient amounts of selenium present both in males and females as well.

The aim of this chapter is to demonstrate the importance and necessity of bringing together the considerations of language and reproduction. While other topics of sexuality have aroused interest in sociolinguistics and linguistic anthropology, the ideas, practices, and experiences of human reproduction, notably pregnancy, remain understudied. At the same time, a discussion of language has been largely absent from the anthropology of reproduction, which has emerged in the last twenty years as an especially vibrant area of cultural and social study. The chapter examines the metaphors and discourses or the “talk about” reproduction; the interactions and “talk between” people, like pregnant women and medical health care providers, which shapes the ordinary experiences of reproduction; the “talk to” parties (specifically, fetuses and imagined children) who themselves become constituted through talk; and reproduction as literacy event or one that is mediated and experienced in relation to texts. It is asserted that language is a practice of reproduction.

Abstract Objective To illustrate the importance of treatment duration with intramuscular testosterone undecanoate (Nebido®) for the final spermatogenesis recovery after treatment cessation. Also, to show a subsequent poor efficacy of the selective estrogen receptor modulator (SERM) clomiphene citrate (CC) in treating steroid-induced azoospermia following Nebido® cessation and describe that initial oligozoospermia, existing before starting Nebido®, largely contributes to that treatment outcome. Methodology Setting: Department of Human Reproduction and Department of Endocrinology, Clinical Hospital Center Rijeka, Rijeka, and Department of Endocrinology, Clinical Hospital Center Sestre milosrdnice, Zagreb, Croatia. Patient: A male patient having been diagnosed with primary hypogonadotropic hypogonadism, oligozoospermia and low testosterone (T) level, was treated with intramuscular testosterone undecanoate (TU) depot 1 g (Nebido®) to prevent further progression of testosterone deficiency symptoms (low mood, energy and concentration, fatigue, muscle weakness). Interventions: Stopping Nebido® and treatment with CC 50 mg per day 5 days per week for 3–6 month to recover spermatogenesis. Main outcome measures: T levels and semen analyses. Results Semen analyses did not return to values before taking Nebido® 1 year after cessation nor after 3 months of treatment with CC. Values of T, follicle stimulating hormone (FSH) and luteinizing hormone (LH) dropped even more than before starting Nebido®, after 1 year of cessation. Conclusions Here we describe a case of initially idiopathic gonadal failure with subsequent secondary gonadal failure and infertility resulting from testosterone replacement therapy (TRT) treatment, and poor spermatogenesis recovery outcome of CC used post Nebido® cessation.

Abstract The primary objective of this glossary is to give clear definitions for those who contribute to studies relevant to these disciplines, or who must interpret them, but are not themselves reproductive physiologists or physicians. This applies especially to chemists who need to understand the literature of reproductive and teratogenic effects of substances without recourse to a multiplicity of other glossaries or dictionaries. The glossary includes terms related to basic and clinical reproductive biology and teratogenesis, insofar as they are necessary for a self-contained document, particularly terms related to diagnosing, measuring, and understanding the effects of substances on the embryo, the fetus, and on the male and female reproductive systems. The glossary consists of about 1200 primary alphabetical entries and includes Annexes of common abbreviations and examples of chemicals with known effects on human reproduction and development. The authors hope that toxicologists, pharmacologists, medical practitioners, risk assessors, and regulatory authorities are among the groups who will find this glossary helpful, in addition to chemists. In particular, the glossary should facilitate the worldwide use of chemical terminology in relation to occupational and environmental risk assessment.

The Relationship

Abstract Objectives There is a growing evidence indicating an impact of endocrine distrupting chemicals such as bisphenol A (BPA) on human reproduction. Its higher levels in serum or urine have been documented in women with polycystic ovary syndrome (PCOS), however the relationship to ovarian steroidogenesis remains unclear. Aim of the study was to compare urinary BPA (U-BPA) concentrations among PCOS women and control group. Second aim was to assess the relationship of U-BPA to ovarian steroidogenesis in the group with PCOS. Methods Eighty six Caucasian women (age 28.5 ± 5.1 years) diagnosed with PCOS and 32 controls of age 24.9 ± 4.4 years were included in the study. Fasting blood samples were analyzed for biochemical parameters and steroid hormones. U-BPA was measured in the morning urine sample using high pressure liquid chromatography. Results PCOS women had significantly higher U-BPA as compared with control group (p=0.0001). Those with high levels of U-BPA (U-BPA ≥2.14 ug/g creatinine) demonstrated higher serum insulin (p=0.029) and HOMA IR (p=0.037), lower serum estrone (p=0.05), estradiol (p=0.0126), FSH (p=0.0056), and FAI (p=0.0088), as compared with low-BPA group (U- BPA <2.14 ug/g creatinine). In PCOS women, U-BPA positively correlated with age (p=0.0026; R2=0.17), negatively with estradiol (p=0.0001, R2=0.5), testosterone (p=0.0078, R2=0.15), free-testosterone (p=0.0094, R2=0.12) and FAI (p=0.0003, R2=0.32), respectively. Conclusions PCOS women have significantly higher U-BPA concentrations than healthy controls. U-BPA positively correlates with age and negatively with ovarian steroid hormones suggesting a possible suppressive effect of bisphenol A on ovarian steroidogenesis.
