: While tubal occlusion is a prevalent cause of infertility, accounting for 11-35% of infertility cases among women, there remains a limited understanding of the factors influencing clinical pregnancy following in vitro fertilization (IVF). : In our retrospective, cross-sectional cohort study conducted at a single tertiary center, medical records of women aged 19 to 43 years were analyzed. Logistic regression models were employed to identify the prognostic factors associated with clinical pregnancy after IVF in patients with tubal factor infertility, excluding cases with hydrosalpinx.

Introduction: The impact of the obesity pandemic on female reproductive capability is a factor that needs to be investigated. In addition, the link between endometrial thickness and fertilization (IVF) outcomes is contentious.

Goal: Our goal was to analyze the association among endometrium development, hormone levels, embryo quality, clinical pregnancy, anamnestic parameters, and body mass index (BMI) in women receiving IVF treatment.

Numerous diseases can arise as a consequence of mitochondrial malfunction. Hence, there is a significant focus on studying the role of mitochondria in cancer, ageing, neurodegenerative diseases, and the field of developmental biology. Mitochondria could exist as discrete organelles in the cell; however, they have the ability to fuse, resulting in the formation of interconnected reticular structures.

Objective: Fertility-sparing surgery (FSS) aims to achieve oncological outcomes that are non-inferior to radical treatment while preserving fertility and optimizing reproductive results. This study assesses in vitro fertilization (IVF) outcomes in early-stage cervical cancer survivors following FSS, comparing radical and non-radical approaches.

Methods: This retrospective analysis used data from Hungary's National Health Insurance Fund (2004-2022) on patients who underwent IVF treatment following FSS for early-stage cervical cancer at ten Hungarian fertility clinics.

Aims: The importance of contributing psychological factors and stress-control in female infertility is well documented, but research on their role in male infertility is scarce. The present study aimed to evaluate the effects of a novel paramedical counselling on anxio-depressive symptom severity, perceived stress and self-esteem in infertile men participating in an infertility treatment programme.

Methods: Patients were recruited from clinics of University of Szeged, Hungary between 2019 May and 2020 December, and were sorted into control (n = 51) and experimental (n = 57) groups, where patients in the experimental group received a 5-session paramedical counselling in extension to their medical treatment.

: In the last decades, the number of infertile males increased worldwide which gained more focus. The extent to which a person or a couple is able to cope adaptively with the problem of infertility depends on the combined effect of several variables. Our aim was to apply counselling among males suffering from infertility problems.

Purpose: To evaluate whether vanishing twin (VT) pregnancies following spontaneous conception have a more adverse perinatal outcome than those conceived after assisted reproduction techniques.

Methods: The retrospective cohort study consisted of 316 VT pregnancies derived from a hospital database between January 1994 and January 2016 (81 after IVF/ICSI and 235 after spontaneous conception).

Results: VT was significantly more prevalent after spontaneous conception (in 22.

Appropriate selection of a single blastocyst for transfer decreases the risk of multiple gestations. By using a compact time-lapse microscope system placed inside a regular incubator, combined with a microwell embryo culture dish, the development of all the embryos from a patient was continuously monitored by obtaining images at 10 min intervals. The embryos were not moved during the time-lapse observation.

Purpose: To determine contributing psychosocial factors to postnatal depression (PND) in Hungary in 1996 and in 2006.

Methods: In 1996 and 2006, a total of 2,333 and 1,619 women, respectively, were screened for PND in South-Eastern Hungary, based on a Leverton questionnaire (LQ) score of ≥ 12 at 6-10 weeks after delivery.

Results: The LQ scores indicated an increase in PND from 15.

Cigarette smoking has been reported to induce intrafollicular oxidative stress that may lead to DNA damage. The purpose of this study was to determine damage in DNA in human cumulus cells caused by tobacco smoke in females who had received in vitro fertilization. The level of DNA damage in freshly isolated cumulus cells was determined by comet assay.
