This paper considers ethical questions related to different forms of surrogacy. It concludes that non-commercial surrogacy is an acceptable method of assisted reproduction for specific indications. When using surrogacy to form a family, it is essential that there are measures to protect all parties, to guarantee well-considered decision-making, and to minimize risks.

To the best of our knowledge, no previous studies have quantified the average reduction in working hours during the entire span of working life using population-based registers.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study design, size, duration: &lt;/strong&gt;This study included two Danish data sources. In the register-based cohort study (main analysis), a total of 2 650 554 women aged 18-65 years were followed for a total of 42.8 million person-years from 1992 to 2021. In the questionnaire-based cross-sectional study (Supplementary Analysis), 35 490 women aged 26-51 years were invited to participate and 7298 women completed the questionnaire.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Participants/materials, setting, methods: &lt;/strong&gt;For the main analysis, 42 741 (1.6%) were diagnosed with endometriosis. We estimated working years lost decomposed into disability pension, voluntary early retirement, or death for women with endometriosis and the general female population. For the supplementary analysis, 270 (4.0%) reported to have endometriosis. We analysed these recent questionnaire data on women's health to further investigate working life and productivity among women with and without endometriosis.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Main results and the role of chance: &lt;/strong&gt;Based on the main analysis, women with endometriosis lost on average an additional 0.26 years (95% CI: 0.17-0.37) of working life compared to the general female population. This was due to sick leave and especially disability pension. For the supplementary analysis, the participation rate was 20.6%. Women with endometriosis reported to be less frequently working or enrolled in education (74.1% (95% CI 68.4%-79.2%) with endometriosis, 82.7% (95% CI 81.8%-83.7%) without) and had more sick days (4-28 sick days last 4 weeks: 16.2% (95% CI 11.6%-21.8%) with endometriosis, 7.9% (95% CI 7.2%-8.7%) without). In addition, they reported lower productivity and work ability.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Limitations, reasons for caution: &lt;/strong&gt;Endometriosis is underdiagnosed in the register data as only hospital diagnoses are registered and diagnoses from private practicing gynaecologists and general practitioners are missing.

Despite this, multiple birth rates following IVF remain higher than the 10% target across Europe and the USA. Currently, the majority of evidence regarding SET and DET is based on various studies assessing outcomes such as LBR per treatment cycle, as opposed to per oocyte retrieval. As such, the representation of SET is mostly unfavourable. Analysis of cumulative LBR following the transfer of two embryos over consecutive cycles, rather than in one transfer event (DET) is more effective at distinguishing the two methods and will therefore provide more valuable information relevant to clinical practice.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study design, size, duration: &lt;/strong&gt;This retrospective cohort study was conducted using Human Fertilisation and Embryology Authority (HFEA) register data, which encompasses national data from all IVF clinics in the UK. All women who underwent their first oocyte retrieval and IVF or ICSI treatment cycle with subsequent SET, DET, or 2xSET between 2010 and 2019 using blastocyst embryos were included (N = 71 807).&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Participants/materials, setting, methods: &lt;/strong&gt;The rate of live birth, liveborn baby rate, multiple birth, preterm birth, and pregnancy loss or neonatal death was compared between SET, DET, and 2xSET IVF/ICSI pregnancies using blastocyst-stage embryos, where data were stratified by maternal age. Data analysis was conducted in RStudio v4.2, alpha equals 0.05.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Main results and the role of chance: &lt;/strong&gt;Blastocyst-stage 2xSET achieved a greater median LBR of 0.47 (interquartile range [IQR] 0.13) than SET, 0.41 (IQR 0.13), and DET, 0.38 (IQR 0.13) (P &lt; 0.05). Using SET as the reference standard, 2xSET was associated with a significantly lower odds of multiple births compared to DET ((odds ratio [OR] 6.87, 95% CI 6.14-7.68) vs 28.20, 95% CI 25.20-31.57). The odds of preterm birth were also lower following 2xSET (OR 1.11, 95% CI 1.06-1.15) compared to DET (OR 2.80, 95% CI 2.67-2.94). Similarly, the odds of pregnancy loss or neonatal death were lower following 2xSET (OR 1.14, 95% CI 1.08-1.21) compared to DET (OR 2.11, 95% CI 1.98-2.24). LBR was consistently higher following 2xSET than DET and SET in women aged 39 years and under (P &lt; 0.05). However, results were comparable in women over 39 years (P &gt; 0.05).

SUMMARY ANSWER Even in a laboratory environment with a total VOC concentration lower than the recommendation of the Cairo Consensus, the real-time monitored VOC concentrations are associated with changes in embryo morphological parameters. WHAT IS KNOWN ALREADY VOCs have been considered a key environmental detriment in embryology laboratories. However, the current VOC thresholds established by the Cairo consensus were based on the practical experience of air pollution cases, and a scientifically derived threshold is lacking. STUDY DESIGN, SIZE, DURATION The study included 7076 oocyte collection (OPU) cycles carried out between June 2020 and December 2022 in the Center for Reproductive Medicine of the affiliated Chenggong Hospital of Xiamen University, 6306 of which resulted in at least one embryo transfer (ET) attempt during the study. VOC monitoring data were recorded every 10 min. The average and peak concentrations of total VOCs and formaldehyde during culture were associated with embryo parameters and implantation following the first ET attempt of the cycle in generalized estimating equations and generalized additive models. MAIN RESULTS AND THE ROLE OF CHANCE Real-time monitoring of VOCs showed a dynamic of VOC concentration in the laboratory. The concentration reached peaks during the working hours of the days and working days of the week and fell quickly at night and on weekends. The average concentrations of VOCs during the culture period were linearly associated with decreased early cleavage (OR 0.92, 95% CI: 0.85, 0.99), decreased Day 3 compaction (OR 0.51, 95% CI: 0.32, 0.83), increased asymmetry (OR 1.13, 95% CI: 1.01, 1.25), and increased grade C trophectoderm (TE) (OR 1.99, 95% CI: 1.32, 3.01). On the other hand, increased Day 3 arrest, delayed blastocyst formation, and decreased grade A TE showed a non-linear association with VOCs, suggesting a possible threshold of effect. In the first transfer attempt, negative associations were observed between maximal formaldehyde concentrations and pregnancy in both fresh transfer (RR 0.971, 95% CI: 0.94, 0.99) and freeze-all frozen-thawed ET (RR 0.959, 95% CI: 0.92, 0.99) cycles. LIMITATIONS, REASONS FOR CAUTION The sensitivity and specificity of the monitor are not comparable to the standard protocols, such as chromatography-mass spectroscopy. Due to the lack of ability to identify the chemical nature of the components of VOCs, the toxicity and source of the VOCs were largely unknown. The representative sampling of the laboratory air may not necessarily reflect the exposure of embryos. WIDER IMPLICATIONS OF THE FINDINGS While the environment of the embryology laboratory has been significantly improved, the data suggested that a low VOC level could still be a concern.
