OBJECTIVES: Bacteriospermia may result in male hypofertlity. Indeed, 60% of patients treated by Assisted Reproductive Techniques had a local infection or inflammation of genital tract. However, direct effects of bacteriospermia on semen parameters remain controversial. The aim of our work was to explore the effect of bacteriospermia on sperm parameters among patients consulting for hypofertility. METHODS: A retrospective comparative study of two groups: a group of 70 patients with bacteriospermia (group 1) and a control group of 70 patients without bacteriospermia (group 2)...

Long noncoding RNAs (lncRNAs) constitute a major class of the human transcriptome which play crucial roles in the key biological processes of both normal and malignant breast cells. Although the aberrant expression of lncRNAs has been well-documented in breast cancer (BC), little is currently known about the association between their expression levels in the breast tissue of healthy women and BC risk factors, especially the reproductive or demographic characteristics that are among the most well-known BC risk modifiers...

Template induced replication is the basis of multiplication and reproduction in nature and underlies the importance of gaining a detailed understanding of its mechanisms in terms of chemical reaction networks. We analyze numerically the stationary state solutions for a class of autocatalytic reactions based on reversible template assisted ligation with first and second order catalysis and governed by mass-action kinetics. Chemical thermodynamics leads to constraints on the reaction rate constants which result in very low template yield in systems subject to fixed external concentrations...

PURPOSE: To develop a comprehensive genetic test for female and male infertility in support of medical decisions during assisted reproductive technology (ART) protocols. METHODS: We developed a next-generation sequencing (NGS) gene panel consisting of 87 genes including promoters, 5' and 3' untranslated regions, exons, and selected introns. In addition, sex chromosome aneuploidies and Y chromosome microdeletions were analyzed concomitantly using the same panel. RESULTS: The NGS panel was analytically validated by retrospective analysis of 118 genomic DNA samples with known variants in loci representative of female and male infertility...

RESEARCH QUESTION: Do cumulative live birth rates (CLBR) vary among women with different polycystic ovary syndrome (PCOS) phenotypes who undergo IVF/intracytoplasmic sperm injection (ICSI) treatment? DESIGN: In this retrospective cohort study, data from 567 patients undergoing an assisted reproductive technology (ART) cycle between January 2010 and December 2015 were collected. Demographical traits, cycle characteristics and clinical and laboratory data were analysed...

REVIEW
Dominique de Ziegler, Paul Pirtea, Claus Yding Andersen, Jean Marc Ayoubi
Luteal phase support is mandatory in ovarian stimulation cycles in assisted reproductive technology owing to a deficit in LH pulsatility after the effects of exogenous hCG-used for triggering ovulation-vanish. This is classically accomplished by means of exogenous P administration, but emerging new options include microdoses of hCG and exogenous GnRH agonist. Although luteal phase support is commonly continued for up to 10 weeks into pregnancy, there is accumulating evidence that it can be stopped after the first ultrasound or even after a positive pregnancy test...

Georg Griesinger, David Meldrum
The increasing utilization of a gonadotropin-releasing hormone agonist ovulation trigger and the widespread use of artificial cycles for the transfer of frozen-thawed or donated embryos has renewed interest in the luteal phase in assisted reproductive technology. The "luteal phase defect" phenomenon is now understood as a continuum: there is less impairment with milder stimulation than with more intense ovarian stimulation, and less impairment after controlled ovarian stimulation and human chorionic gonadotropin ovulation triggering than after gonadotropin-releasing hormone agonist ovulation triggering, the latter being associated with rapid luteolysis...

INTRODUCTION: Assisted Reproductive Technologies (ART) is increasingly used to help infertile couples to have children around the world. A number of studies have been published reporting an increased risk of major malformations in children born following ART, especially an increased incidence of epigenetic diseases (ED). This study aimed to assess the incidence of epigenetic diseases with affected imprinting genes in infants or children from pregnancies obtained through IVF/ICSI compared to infants or children from pregnancies obtained spontaneously...

REVIEW
Daniel J Mazur, Larry I Lipshultz
PURPOSE OF REVIEW: In many countries, the average age of paternity is rising. The negative effect of older age on fertility in women is well documented; however, less is known about the impact of paternal age on fecundity. In this review, we summarize the current knowledge of how paternal age affects semen parameters, reproductive success, and offspring health. RECENT FINDINGS: Contemporary evidence confirms that aged men have worse semen parameters, including overall negative changes in sperm genetics...

This study presents an economic assessment of controlled ovarian stimulation in assisted reproductive technology procedures in Spain, comparing the use of corifollitropin alfa and various forms of recombinant follicle-stimulating hormone (rFSH) in women of advanced maternal age. A cost-minimization analysis (CMA) was performed to assess the cost per cycle of controlled controlled ovarian stimulation, including only direct costs associated with the stimulation phase. The CMA was based on the population characteristics, the protocol, and the results obtained from the PURSUE study, taking into account 9 days of controlled controlled ovarian stimulation and 300 IU rFSH/day...

Many patients who might benefit from treatment using assisted reproductive technology (ART) do not receive it, raising critical questions of why, and how best to overcome existing barriers. In-depth interviews of approximately 1 h each were conducted with 27 ART providers (17 physicians and 10 other healthcare providers). These interviewees suggest that non-ART providers may serve as gatekeepers in a complex system, involving not only individual-level, but also dyadic and institutional, processes and factors related to provider-patient relationships...

In a nationwide population-based birth cohort study in Japan, pregnant women and their partners were evaluated for psychological distress as part of the first and second/third trimester health checks. Participants were divided into three groups: an infertility group receiving assisted reproductive technology (ART) treatment (239 mothers and 151 fathers); an infertility group receiving non-ART treatment (350 mothers and 215 fathers); and a spontaneous pregnancy group (8514 mothers and 5110 fathers). Data on maternal and child health as well as basic characteristics were collected via medical records and self-administered questionnaires...
