Nutrition, female fertility and in vitro fertilization outcomes.

The investigation of modifiable factors that may exert influences on female reproductive health and in vitro fertilization (IVF) outcomes is increasing. Growing attention is being paid to nutrition. The aim of the present review is to recapitulate the current understanding on the effects of nutrition on female fertility and IVF outcomes.

An updated meta-analysis comparing the efficacy and safety of biosimilar medicinal products to the original follitropin alfa.

Introduction: The aim of this study was to provide an updated meta-analysis assessing the therapeutic equivalence between follitropin alfa biosimilars and the reference medication in women undergoing assisted reproductive technologies (ART).

Evidence Acquisition: The studies included in the analysis were pooled together in order to estimate the log odds ratio (OR) for binary outcomes and the mean difference (MD) for continuous outcomes along with the corresponding 95% confidence intervals (CI) by using a random effects model. The heterogeneity between the studies was evaluated with the Higgins and χ tests.

Profiling of mitochondrial heteroplasmy in single human oocytes by next-generation sequencing.

Mitochondrial DNA (mtDNA) plays a crucial role in the development of a competent oocyte. Indeed, mtDNA alterations may predispose to chromosome nondisjunction, resulting in infertility due to a reduced vitality and quality of oocytes and embryos. In this methods paper, the multiple displacement amplification approach was applied in combination with next-generation sequencing (NGS) to amplify and sequence, in single-end, the entire mtDNA of single human oocytes to directly construct genomic NGS libraries, and subsequently, to highlight and quantify the mutations they presented.

Fertility sparing treatment for bilateral borderline ovarian tumor: a case report and management strategy explication.

A bilateral adnexal mass with suspected carcinosis could be a challenging experience for the gynecologist especially in fertile age and in patients with a desire for pregnancy. A 26-year-old patient who came to the outpatient clinical observation for bilateral, multilocular pelvic masses, with more than 4 papillary structures, color score 2, hypomobile compared to the uterus and rectum, respectively of 65 and 68mm in maximum diameter, free liquid in the abdomen and suspected of ovarian neoplasm. Positive tumor markers and a strong desire of a fertility sparing treatment (FST).

The Aftermath of Long-Term Cigarette Smoking on Telomere Length and Mitochondrial DNA Copy Number in Human Cumulus Cells Prior to In Vitro Fertilization-A Pilot Study.

Cigarette smoking among women of reproductive age is known to take a toll on systemic health and fertility potential by severely impacting ovarian tissues and cells, such as granulosa and cumulus cells (CCs). The purpose of this study was to determine the potential damage caused by tobacco smoke at a molecular level in the CCs of females who had undergone in vitro fertilization. The level of intracellular damage was determined by estimating the average telomere length (TL) and mitochondrial DNA copy number (mtDNA-CN), as well as the expression profile of telomere maintenance genes TERF1, TERF2, POT1 and microRNAs miR-155, miR-23a and miR-185.
