Buch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - How often is male idiopathic infertility diagnosed nowadays It is estimated that 70% of male infertility is apparently idiopathic because its etiology cannot be found despite a complete diagnostic procedure. Epidemiological studies have highlighted that sperm concentration and total count have halved in the past forty years. The reasons for this decline are still unknown and, therefore, it is urgently necessary to research the etiopathogenetic moments. Given that Sertoli cells are responsible for supporting spermatogenesis, much attention should be focused on their function. During childhood, these cells have peculiar characteristics. After the onset of puberty, they reach a state of maturity and lose their ability to proliferate. Therefore, several environmental or lifestyle factors in childhood could reasonably interfere with the proliferation of Sertoli cells and this may be the cause of so-called idiopathic infertility in adulthood. For that reason, this book explores molecular aspects involving prepubertal Sertoli cells, risk factors for infertility in the early stages of life, and the correct management of andrological health from the first months of life and during infancy and adolescence. A close collaboration between pediatricians, endocrinologists, and andrologists is of fundamental importance to achieve an important goal: To protect the health of the fathers of tomorrow. …

Buch. Condición: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - This Special Issue titled 'Hot Topics in Reproductive Medicine Research' tries to cover some of the most debated topics in this field from a scientific and clinical point of view. In particular, the quality of embryos using compared tools such as incubator time-lapse and aneuploidy detection, the endometrioma impact on embryo quality, the influence of paternal age on obstetrical and perinatal outcome in IVF, and the possibility of performing assisted reproductive technology (ART) without discarding or freezing embryos. Other articles deal with PCOS and the patterns of patients who develop ovarian hyperstimulation syndrome with a granulosa cells transcriptional profile, PCOS and Vitamin D deficiency, new treatment of oligoasthenoteratozoospermia with antioxidants and natural hormones, general epigenetic risks in ART with special interest on gametes and embryos produced by cryopreservation, decision to treat or not and when varicocele, and the impact of a short abstinence period on sperm quality. Moreover, other interesting topics regard the placental volume and uterine artery doppler in pregnancy after IVF, the efficacy of autologous platelet intrauterine infusion in repeated embryo implantation failures, and DNA methylation in offspring after IVF.…
