Objective: Various gonadotropins are used for ovarian stimulation (OS). This study investigated the cost-effectiveness of different gonadotropins based on real-world data from the French National Health Database (SNDS) over a 7-year follow-up of assisted reproductive technology (ART) treatments.

Design: Cost-effectiveness analysis of different gonadotropins based on real-world data from the SNDS was conducted.

Article Synopsis
  • The objective of the study is to evaluate how well ovarian stimulation (OS) promotes follicular development and retrieves quality oocytes by examining antral follicle count (AFC) and its relationship to oocyte outcomes.
  • The study emphasizes the need to enhance the key performance indicators (KPIs) used to assess OS effectiveness, introducing new metrics like "early FORT" and "modified FORT" for better evaluation of follicular growth and oocyte retrieval rates.
  • The researchers advocate for incorporating these refined KPIs into clinical practices to improve the assessment of OS and its impact on ovarian follicular development, ultimately aiming for individualized treatments in assisted reproductive technology.

Research Question: According to real-world data, is recombinant human FSH (r-hFSH) combined with recombinant human LH (r-hLH) or r-hFSH alone more effective for women of advanced maternal age (AMA) in terms of live birth?

Design: Non-interventional study comparing the effectiveness of r-hFSH and recombinant r-hLH (2:1 ratio) versus r-hFSH alone for ovarian stimulation during ART treatment in women aged 35-40 years, using real-world data from the Deutsches IVF-Register.

Results: Overall clinical pregnancy (29.8%, 95% CI 28.

This was a retrospective real-world evidence analysis of the costs per live birth for reference recombinant human follicle-stimulating hormone alfa (r-hFSH-alfa) versus highly purified urinary human menopausal gonadotropin (hMG-HP), based on data from a German in vitro fertilization registry (RecDate). Pregnancy and live birth rates from the RecDate real-world evidence study over three complete assisted reproductive technology (ART) cycles using the same gonadotropin drug were used as clinical inputs. Costs related to ART treatment and to drugs were obtained from public sources.

This study compared the cost per live birth and cost-effectiveness of the originator recombinant human follicle-stimulating hormone follitropin alfa (r-hFSH-alfa) and r-hFSH-alfa biosimilars for ovarian stimulation prior to assisted reproductive technology treatment in Spain. A decision tree model was developed, comprising pregnancy and live birth for one treatment cycle with fresh embryo transfer. Clinical inputs were based on a recent meta-analysis by Chua et al.

Study Question: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting?

Summary Answer: Consensus definitions for individual core outcomes, contextual statements and a standardized reporting table have been developed.

What Is Known Already: Different definitions exist for individual core outcomes for infertility. This variation increases the opportunities for researchers to engage with selective outcome reporting, which undermines secondary research and compromises clinical practice guideline development.

Objective: To estimate the effectiveness of Atosiban in improving the outcome after embryo transfer. The effectiveness of embryo transfer per cycle is still relatively low. One possible explanation might be uterine contractility that expels the transferred embryos.

Article Synopsis
  • The study analyzed assisted reproductive technologies (ART) in Latin America during 2016, collecting data from 178 institutions across 15 countries, resulting in 85,474 initiated cycles and 15,070 deliveries.
  • A significant portion of ART cycles were performed on women aged 35-39 (40.9%) and 40+ years (31.1%), with a delivery rate of 20.31% for ICSI and 21.85% for IVF, while single embryo transfers had a delivery rate of 15.35%.
  • The findings suggest a trend towards fewer embryos being transferred, leading to a decrease in multiple births, emphasizing the need for ongoing support for this practice in healthcare.

Research Question: What was the utilization, effectiveness and perinatal outcome of assisted reproductive technologies (ART) performed in Latin America during 2016?

Design: Retrospective collection of multinational data on ART performed in 178 institutions from 15 Latin American countries.

Results: This paper reports on 85,474 initiated cycles, 15,070 deliveries and 18,182 babies born in this period. Of all fresh autologous IVF/intracytoplasmic sperm injection (ICSI) cycles, 40.

Research Question: What was the utilization, effectiveness and safety of assisted reproductive technologies (ART) performed in Latin American countries during 2015, and what were the regional trends?

Design: Retrospective collection of multinational data on assisted reproduction techniques (IVF and intracytoplasmic sperm injection [ICSI], frozen embryo transfer, oocyte donation, preimplantation genetic testing and fertility preservation), from 175 institutions in 15 Latin American countries.

Results: In total, 41.25% of IVF/ICSI cycles were performed in women aged 35-39 years, and 28.

The effects of acupuncture on IVF outcomes is still unknown. We carried out a systematic review and meta-analysis of RCT to determine whether acupuncture performed at the time of ET improves outcomes. We searched Medline and Embase from January 1990 to June 2017, for the following terms): (acupuncture; acupuncture therapy) and (reproductive techniques, assisted; in vitro fertilization; embryo transfer).

The aim of this review is to determine if the use of DHEA increases the likelihood of success in patients with POR. We searched MEDLINE and EMBASE using the terms "DHEA and diminished ovarian reserve", "DHEA and poor response", "DHEA and premature ovarian aging". A fixed effects model was used and Peto's method to get the odds ratio (OR) with 95% confidence intervals (CI 95%).

Women submitted to ART treatments represent a select subgroup of individuals. Several studies have described the relationship between TAI and pregnancy outcomes as a result of ART, with contradictory results. The purpose of this systematic review was to determine the association between TAI and the risk of miscarriage in pregnancies resulting from ART.

Study Question: Does the use of ICSI offer any outcome advantage over IVF in patients with non-male factor infertility?

Summary Answer: We did not find any outcome improvement that justifies the routine use of ICSI over IVF in non-male factor ART cycles.

What Is Already Known: Since its introduction in Latin America, the use of ICSI has increased substantially, even among patients without male factor infertility. However, it is not clear whether ICSI provides an advantage over IVF in non-male factor infertility.

Article Synopsis
  • ICSI has been a significant option for infertile couples since 1992, especially those with severe male infertility and a history of unsuccessful IVF.
  • A systematic review analyzed 21 out of 104 studies to evaluate the risk of congenital malformations in children born through ICSI compared to those conceived naturally.
  • The findings suggest that ICSI children have a higher risk of malformations (7.1%) compared to the general population (4.0%), but it's debated whether ICSI is solely responsible, as other factors may also contribute to the increased risk.

The last two decades have seen an increase in the number of women diagnosed with infertility. The consequent growth in the use of assisted reproductive technologies (ART) calls for the determination of its long-term effects, including the risk of cancer. Many studies have attempted to answer this question, albeit with contradictory results.
