infertily

BACKGROUND: Non-obstructive azoospermia (NOA) is considered to be the most severe form of male infertility. Before the emergence of surgical testicular sperm extraction and assisted reproductive technology, NOA patients could hardly become biological fathers of their children. However, failure of the surgery could cause physical and psychological harm to patients such as testicular damage, pain, hopeless of fertility and additional cost. Therefore, predicting the successful sperm retrieval (SSR) is so important for NOA patients to make their choice whether to do the surgery or not...

AIM: microdeletions in the AZF region of Y-chromosome, compound heterozygotes of severe and mild CFTR mutations, and long CAG-repeats in the androgen receptor gene (AR) as marker of predisposition are frequently studied as genetic causes of male infertility. A simultaneously testing of the panel including biochemical, immunological, cyto- and molecular genetic markers is often performed during the complex laboratory diagnostics in infertile men. The aim of our work was to identify molecular genetic alterations, which are advisable for simultaneously testing in a man with currently uncertain form of infertility, to increase the informativeness of laboratory diagnostics...

OBJECTIVE: To describe the prevalence of Y-chromosome microdeletions in a multi-ethnic urban population in London, UK. To also determine predictive factors and a clinical threshold for genetic testing in men with Y chromosome microdeletions. PATIENTS AND METHODS: A retrospective cohort study of 1473 men that were referred to a tertiary Andrology centre with male factor infertility between July 2004 and December 2016. All had a genetic evaluation, hormonal profile and 2 abnormal semen analyses...

Species of Diaporthe are considered important plant pathogens, saprobes, and endophytes on a wide range of plant hosts. Several species are well-known on citrus, either as agents of pre- or post-harvest infections, such as dieback, melanose and stem-end rot on fruit. In this study we explored the occurrence, diversity and pathogenicity of Diaporthe species associated with Citrus and allied genera in European orchards, nurseries, and gardens. Surveys were carried out during 2015 and 2016 in Greece, Italy, Malta, Portugal, and Spain...

Hypofertility is defined as the absence of conception after one year of trying. Women's exploration needs biologist attendance for the ovarian reserve evaluation and radiologist attendance for the exploration of the uterus, the fallopian tubes and the ovary. The management of women's treatment as ovarian stimulation combine hormonal levels and transvaginal ultrasonography during all the treatment. The collaboration between clinician and biologist is necessary for the diagnosis and during women's infertily treatment...

Surgery for male infertility includes three main areas: varicocele surgery, recanalization of seminal tract, sperm retrieval.Varicocele treatment in infertily is still controversial. Recent scientific evidence appears to demonstrate that in selected cases varicocele treatment is beneficial in improving semen parameters and pregnancy rate. The key for the success of treatment seems to be a correct indication. It is our opinion that varicocele should be treated in presence of abnormal semen parameters, when clinically significant, and in adolescents with atrophy of the affected testis...

OBJECTIVE: To evaluate whether the surgical resection or aspiration with ethanol sclerotherapy (AEST) of endometrioma before in vitro fertilization (IVF) affect controlled ovarian stimulation (COS) and IVF outcome in the infertilie women with endometroma undergoing IVF. METHODS: In this retrospective cohort study, 101 consecutive IVF/intracytoplasmic sperm injection cycles that were performed in 101 patients with endometrioma(s) between January 2008 and December 2012 were included...

The noise stress, after it passes through the hearing apparatus, not only affects the auditory apparatus but also other body functions. The alterations in the levels of cortical hormone, adrenocorticosterone, nor-epinephrine hormone (which are primarily considered as stress hormones) on follicular stimulating hormone, testosterone, and lutinizing hormone were reported in relation with stress. Male albino rats weighing 200 to 250 grams were exposed to 100 dB of noise for one hour and three hours in acute group and daily one hour exposure for 60 day, and 90 day in chronic group...

Bisphenol A [2,2-bis(4-hydroxyphenyl)propane] (BPA), 4-nonylphenol (NP) and di(2-ethylhexyl)phthalate (DEHP), and its metabolite mono-2-ethylhexyl phthalate (MEHP) are chemicals found in plastics, which act as endocrine disruptors (EDs) in animals, including human. EDs act like hormones in the endocrine system, and disrupt the physiologic function of endogenous hormones. Most people are exposed to different endocrine disruptors and concern has been raised about their true effect on reproductive organs. In the testis, they seem to preferentially attack developing testis during puberty rather than adult organs...

INTRODUCTION: Anal atresia is a congenital anomaly, very life-threatening and urgent. Surgical treatment of this anomaly consists of colostomy first, and then of anal reconstruction. CASE REPORT: We presented a 31-year old female with the surgery treatment of anal atresia in the early childhood. In the reproductive period, due to tubal infertily, the patient was included in the program of in vitro fertilization (IVF), in the Clinic for Gynecology and Obstetrics "Narodni front", Belgrade...
