Infertility

Millions of people are subject to infertility worldwide and one in every six people, regardless of gender, experiences infertility at some period in their life, according to the World Health Organization. Assisted reproductive technologies are defined as a set of procedures that can address the infertility issue among couples, culminating in the alleviation of the condition. However, the costly conventional procedures of assisted reproduction and the inherent vagaries of the processes involved represent a setback for its successful implementation...

OBJECTIVE: The aim of this study was to investigate the relationship between left-sided varicocele and epididymitis or epididymo-orchitis. MATERIALS AND METHODS: The study included 72 patients with left side epididymitis (EP) or epididymo-orchitis (EPO) (Group 1) and a control group of 72 patients without EP or EPO (Group 2). Those with right EP-EPO were excluded due to possible other underlying retroperitoneal pathologies causing varicocele. Groups were evaluated for presence of left side varicocele, varicocele grade and pampiniform plexus vein diameter...

Infertility can be stressful for infertile couples. This study aims to examine the intra-dyadic associations between stigma, communication patterns, and infertility-related stress in couples undergoing artificial insemination by donor semen (AID). This cross-sectional study was conducted from January to April 2021. Two hundred and three couples undergoing AID were recruited from a reproductive centre in China. All of the couples completed a two-item stigma questionnaire, Communication Pattern Questionnaire, and Fertility Problem Inventory...

STUDY QUESTION: Is the Tcte1 mutation causative for male infertility? SUMMARY ANSWER: Our collected data underline the complex and devastating effect of the single-gene mutation on the testicular molecular network, leading to male reproductive failure. WHAT IS KNOWN ALREADY: Recent data have revealed mutations in genes related to axonemal dynein arms as causative for morphology and motility abnormalities in spermatozoa of infertile males, including dysplasia of fibrous sheath (DFS) and multiple morphological abnormalities in the sperm flagella (MMAF)...

Classical Hodgkin lymphoma is a lymphoproliferative disease with a good prognosis mainly seen in young people. Nevertheless secondary malignancy, cardiac disease and infertility may affect the long survivors with significant impact on quality of life, morbidity and overall survival. In the last decades several treatment strategies were evaluated to reduce the toxicity of first line treatment such as avoiding radiotherapy or its reduction in terms of dosage and extension. Many trials including interim Positron Emission Tomography evaluation fail to compare efficacy between combined modality treatment versus chemotherapy alone in particular in early stage disease...

A review of controversial issues about the terminology on male infertility and reproductive function, which is currently used, as well as proposals for updating clinical guidelines for the diagnosis and treatment of male infertility and men in infertile couples are presented in the article. An algorithm is described, the elements of which ensure referral of patients based on the possibility and timing of restoration of reproductive function, taking into account the reproductive health of a woman, as well as increasing the likelihood of successful treatment aimed at the birth of a healthy child...

INTRODUCTION: Pro-inflammatory cytokine - tumor necrosis factor-alpha (TNF) is one of the components of the seminal plasma proteome; its meaning has not been definitively revealed. A comparative analysis of the concentration of this protein in the blood serum and in the ejaculate and changes in its level in the semen of men with infertility is f scientific interest. THE PURPOSE OF THE STUDY: determination of TNF- level in the blood serum and seminal plasma of healthy men and patients with reduced fertility...

BACKGROUND: Premature ovarian insuffiency (POI) is one of the main cause behind infertility. The genetic analysis of POI should be part of the clinical diagnostics, as several genes have been implicated in the genetic background of it. The aim of our study was to analyse the genetic background of POI in a Hungarian cohort. METHODS: The age of onset was between 15 and 39 years. All patients had the 46,XX karyotype and they were prescreened for the most frequent POI associated FMR1 premutation...

Uterine myomas are the most common pelvic tumors in women, which can lead to abnormal uterine bleeding, abdominal pain, pelvic compression symptoms, infertility, or adverse pregnancy. In this article, we provide a dataset named uterine myoma MRI dataset (UMD), which can be used for clinical research on uterine myoma imaging. The UMD is the largest publicly available uterine MRI dataset to date including 300 cases of uterine myoma T2-weighted imaging (T2WI) sagittal patient images and their corresponding annotation files...

RESEARCH QUESTION: What is the clinical outcome of the first attempt at conception between two embryo selection methods, blastocyst morphology and preimplantation genetic testing for aneuploidies (PGT-A), chosen at the initial physician IVF consultation? DESIGN: In this prospective analysis, a clinical decision regarding embryo selection, blastocyst morphology (group A) or PGT-A (group B) was made during initial physician IVF consultation. Female infertility patients were matched based on maternal age (mean 32...

Endometrioma (OMA), a subtype of endometriosis characterized by the formation of endometriotic cysts in the ovaries, affects 17-44% of individuals diagnosed with endometriosis. Women with OMA often experience compromised fertility, yet the exact mechanisms underlying OMA-associated infertility remain unclear. Notably, existing animal models simulate superficial peritoneal endometriosis (SUP) and deep infiltrating endometriosis (DIE), leaving a notable gap in research focused on OMA. In response to the gap of knowledge, this paper introduces a pioneering OMA-simulating mouse model and provides a comprehensive description of the techniques and procedures employed in the model...

L1 elements are retrotransposons currently active in mammals. Although L1s are typically silenced in most normal tissues, elevated L1 expression is associated with a variety of conditions, including cancer, aging, infertility and neurological disease. These associations have raised interest in the mapping of human endogenous de novo L1 insertions, and a variety of methods have been developed for this purpose. Adapting these methods to mouse genomes would allow us to monitor endogenous in vivo L1 activity in controlled, experimental conditions using mouse disease models...

Rationale: In recent years, nicotinamide adenine dinucleotide (NAD+ ) precursors (Npre) have been widely employed to ameliorate female reproductive problems in both humans and animal models. However, whether and how Npre plays a role in the male reproductive disorder has not been fully clarified. Methods: In the present study, a busulfan-induced non-obstructive azoospermic mouse model was used, and Npre was administered for five weeks following the drug injection, with the objective of reinstating spermatogenesis and fertility...

Cotyledonoid dissecting leiomyoma (CDL) is a rare uterine tumor with unique clinical and histological features. We present a case of a 46-year-old woman with a 3-month history of left-flank pain radiating to the back. The patient had a history of infertility and a previous miscarriage. Ultrasound revealed a solid tissue mass suggestive of a degenerated fibroid. Laparoscopy identified subserosal leiomyoma and leiomyoma in the broad ligament. Histologically, CDL is characterized by disorganized smooth muscle with hyaline degeneration and no evidence of malignancy...

BACKGROUND AND OBJECTIVE: Polycystic ovary syndrome (PCOS) is a complex hormonal disorder that leads to ovarian cysts, irregular ovulation, and hormonal swings in women. It is a complex and heterogeneous condition that affects 4 to 20% of women of reproductive age worldwide and relates to reproductive, metabolic, and psychosocial dysfunction. Dietary and lifestyle modifications have been proposed to play a central role in the management of PCOS. This study aimed to provide a comprehensive systemic overview of the existing literature on the effects of intermittent fasting (IF) and calorie restriction (CR) regimens on disease markers of PCOS...

PURPOSE: Fragile sites are specific chromosomal regions showing gaps, poor staining, contractions, or even breaks in the chromosomes. These spontaneous and heritable fragile sites are prone to structural variations which can lead to adverse reproductive outcomes. This paper aims to present a specific case study of a female patient, with a mosaic karyotype involving chromosome 16q22 fragile site which is very rare in clinic and her experience of infertility. CASE PRESENTATION: A 37-year-old woman is diagnosed with ten-year primary infertility...

BACKGROUND: Endometriosis is a common gynecological condition, with symptoms including pain and infertility. Regurgitated endometrial cells into the peritoneal cavity encounter hypoxia and nutrient starvation. Endometriotic cells have evolved various adaptive mechanisms to survive in this inevitable condition. These adaptations include escape from apoptosis. Autophagy, a self-degradation system, controls apoptosis during stress conditions. However, to date, the mechanisms regulating the interplay between autophagy and apoptosis are still poorly understood...
