STUDY QUESTION: Can a novel targeted next generation sequencing (tNGS) platform accurately detect whole chromosome aneuploidy in a trophectoderm biopsy and provide additional information to improve testing? SUMMARY ANSWER: Karyotypes obtained by tNGS were concordant with other validated platforms and SNP genotyping information obtained can be used for improved detection and quality control. WHAT IS KNOWN ALREADY: qPCR-based whole chromosome aneuploidy screening is highly accurate in comparison to other common methods and has been shown to improve IVF success in two randomized clinical trials...

STUDY QUESTION: Does an increased FSH dose result in higher cumulative live birth rates in women with a predicted poor ovarian response, apparent from a low antral follicle count (AFC), scheduled for IVF or ICSI? SUMMARY ANSWER: In women with a predicted poor ovarian response (AFC < 11) undergoing IVF/ICSI, an increased FSH dose (225/450 IU/day) does not improve cumulative live birth rates as compared to a standard dose (150 IU/day). WHAT IS KNOWN ALREADY: In women scheduled for IVF/ICSI, an ovarian reserve test (ORT) can predict ovarian response to stimulation...

STUDY QUESTION: Does a reduced FSH dose in women with a predicted hyper response, apparent from a high antral follicle count (AFC), who are scheduled for IVF/ICSI lead to a different outcome with respect to cumulative live birth rate and safety? SUMMARY ANSWER: Although in women with a predicted hyper response (AFC > 15) undergoing IVF/ICSI a reduced FSH dose (100 IU per day) results in similar cumulative live birth rates and a lower occurrence of any grade of ovarian hyperstimulation syndrome (OHSS) as compared to a standard dose (150 IU/day), a higher first cycle cancellation rate and similar severe OHSS rate were observed...

BACKGROUND: Sperm DNA fragmentation (SDF) testing has been recognized as a valuable tool in the evaluation of infertile men. Despite that, its routine use in clinical practice is still hampered by the lack of understanding of the specific clinical scenarios where SDF testing is most beneficial. The aim of this study was to investigate fertility specialists evaluation of infertility of SDF testing in the context of male infertility evaluation and assisted reproductive technology. METHODS: A questionnaire was developed to survey the major aspects of SDF testing and was mailed to specialists with demonstrated clinical experience in the field of infertility...

REVIEW
Jacqueline R Ho, Richard J Paulson
The first live birth after IVF was achieved in a purely natural cycle. Because early attempts at IVF were associated with low efficiency, ovarian stimulation was added to achieve a greater margin for error in oocyte retrieval, fertilization, and thus, overall pregnancy success. As technology improved, the intuitive appeal of the natural cycle led investigators to once again attempt IVF without antecedent gonadotropin stimulation. Triggering of ovulation with hCG was added to allow for accurate scheduling of oocyte retrieval and thus increased oocyte yield...

PURPOSE: The Cap-Score™ was developed to assess the capacitation status of men, thereby enabling personalized management of unexplained infertility by choosing timed intrauterine insemination (IUI), versus immediate in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) in individuals with a low Cap-Score™. The objective of this study was to estimate the differences in outcomes and costs comparing the use of the Cap-Score™ with timed IUI (CS-TI) and the standard of care (SOC), which was assumed to be three IUI cycles followed by three IVF-ICSI cycles...

EDITORIAL
W Ombelet, J Goossens
The consequences of involuntary childlessness in developing countries create more wide-ranging societal problems compared to Western societies, particularly for women. Negative psychosocial and economical consequences for childless couples are often severe and underestimated by the local and international society. Infertility treatment is often limited to certain procedures and certain costumers. Most common arguments against supporting infertility care in resource-poor countries are the "overpopulation" and the "limited resources" argument, but they totally neglect the reproductive rights and systematic exclusion of millions of women from the right to reproduce...

Chromosomal translocations and other balanced rearrangements, although usually associated with a normal phenotype, can lead to the transmission of an abnormal unbalanced genome to the offspring. Balanced and unbalanced spermatozoa, being indistinguishable, cannot be selected or deselected for prior to IVF and pre-implantation genetic diagnosis. Spermatozoa from 16 chromosomal rearrangement carriers were studied. After incubation in a hypo-osmotic solution (hypo-osmotic swelling test, or HOST), spermatozoa were fixed on microscope slides...

BACKGROUND: Among subfertile couples undergoing assisted reproductive technology (ART), pregnancy rates following frozen-thawed embryo transfer (FET) treatment cycles have historically been found to be lower than following embryo transfer undertaken two to five days following oocyte retrieval. Nevertheless, FET increases the cumulative pregnancy rate, reduces cost, is relatively simple to undertake and can be accomplished in a shorter time period than repeated in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles with fresh embryo transfer...

BACKGROUND: Human embryonic stem cells (hESCs) hold tremendous promise for cell replacement therapies for a range of degenerative diseases. In order to provide cost-effective treatments affordable by public health systems, HLA-matched allogeneic tissue banks of the highest quality clinical-grade hESCs will be required. However only a small number of existing hESC lines are suitable for clinical use; they are limited by moral and ethical concerns and none of them apply Good Manufacturing Practice (GMP) standards to the earliest and critical stages of gamete and embryo procurement...

Time-lapse imaging (TLI) systems for embryo incubation, assessment and selection are a novel technology available to in vitro fertilization (IVF) clinics. However, there is uncertainty about their clinical and cost-effectiveness and insufficient good quality evidence to warrant their routine use. Despite this, enthusiastic commercial marketing and slipping clinical equipoise have led to the widespread hasty introduction of this technology into practice, often at a considerable expense to the patient. We have reviewed the published literature and aim to summarize the strengths, weaknesses, opportunities and threats of these systems...

The reported overall subfertility rate in Kenia is 26.1% with 50% attributed to tubal factors and 15% due to male factors. This is probably an underestimation taking into consideration that due to the stigma and myths of the disease, many couples are seeking alternative care from religious sects, witchdoctors, herbalists. Because the costs associated with IVF in private centres are only affordable for the happy few, the only true hope for most Kenyans struggling with unintended childlessness lies in the introduction of affordable ART services...

We demonstrated the IVF-ICSI results, perinatal outcomes and cost-effectivity of the patients with advanced age at a tertiary centre. A total of 456 patients categorised into two groups according to age: group 1 (n = 158) (≥39years) and group 2 (n = 298) (<39years) were analysed retrospectively. In addition, subgroup analysis was performed according to the 40 years cut-off. Clinical pregnancy rate was significantly different between the groups (p< .001). Preterm delivery (< 37 gestational week) and low birth weight (< 2500 g) were significantly higher in advanced aged women than youngsters (p< ...

OBJECTIVE: Poor responders represent a frustrating condition for couples undergoing IVF and clinicians, and their treatment remains disputed. To assess the efficacy and the most suitable protocol, we conducted a randomized controlled trial comparing three different protocols of ovarian stimulation in poor responder women: clomiphene citrate (CC) plus a high dose of gonadotropins and GnRH antagonist, flexible GnRH antagonist protocol and a short GnRH agonist protocol. PATIENTS AND METHODS: Between July 2014 and December 2015 we enrolled 250 poor responders in a previous IVF cycle at least 3 months before...
