Objective: To compare the cumulative live birth rate (CLBR) of a gonadotropin-releasing hormone (GnRH) antagonist regimen and a progestin-primed ovarian stimulation (PPOS) regimen in low-prognosis patients according to POSEIDON criteria.
Design: Single-center, retrospective, observational study.
Setting: Henan Provincial People's Hospital, Zhengzhou, China.
Patients: Women aged ≤40 years, with a body mass index <25 kg/m, who underwent fertilization (IVF) or intracytoplasmic sperm microinjection (ICSI) and met POSEIDON low-prognosis criteria.
Intervention: GnRH or PPOS regimen with IVF or ICSI.
Main Outcome Measure: CLBR per oocyte retrieval cycle.
Results: Per oocyte retrieval cycle, CLBR was significantly higher with GnRH antagonist versus PPOS (35.3% vs 25.2%; P<0.001). In multivariable logistic regression analysis, CLBR per oocyte retrieval cycle was significantly lower with PPOS versus GnRH antagonist before (OR 0.62 [95% confidence intervals (CI): 0.46, 0.82; P=0.009]) and after (OR 0.66 [95% CI: 0.47, 0.93; P=0.0172]) adjustment for age, body mass index, infertility type, infertility duration, baseline follicle stimulating hormone, anti-Müllerian hormone (AMH), antral follicle count (AFC), and insemination method. CLBR was numerically higher with the GnRH antagonist regimen than with PPOS, across all of the POSEIDON groups, and was significantly higher in patients aged ≥35 years with poor ovarian reserve [AFC <5, AMH <1.2 ng/mL] (unadjusted, P=0.0108; adjusted, P=0.0243).
Conclusion: In this single-center, retrospective, cohort study, patients had a higher CLBR with a GnRH antagonist versus PPOS regimen, regardless of other attributes.

Legal framework and IVF outcomes: a comparative analysis of fresh and frozen embryo transfers in Switzerland.
Reprod Biomed Online
October 2024
Division of Gynaecological Endocrinology and Reproductive Medicine, University Women´s Hospital, Bern, Switzerland.
Research Question: To what extent do legislative measures impact standard reproductive outcome parameters?
Design: Retrospective cohort study using data from the Swiss national IVF registry analysing the outcomes of 13,908 women undergoing embryo transfers resulting from their first lifetime oocyte retrieval before (2014-2016) or after (2020-2022) revision of the legislation, allowing extended culture for 12 zygotes. Live birth rates (LBR) and cumulative LBR (cLBR) were compared in fresh and frozen embryo transfer strategies in both periods. Adjusted multivariable mixed model analyses were performed to determine OR and incidence rate ratios (IRR).
Childbirth after cancer among 42,896 male adolescents and young adults: a population-based study.
J Natl Cancer Inst

Article Synopsis
- A study analyzed childbirth outcomes in male adolescents and young adults (AYAs) with cancer, identifying a sample of nearly 43,000 cases over a 20-year period.
- The research found that 18% of these AYAs had live births within ten years post-diagnosis, with higher rates observed in those with thyroid cancer compared to gastrointestinal cancer.
- Results indicated increased chances of preterm birth and low birth weight among offspring of male AYAs with cancer, emphasizing the need for reproductive counseling for this group.
The Effect of Traditional Chinese Medicine Treatment on the Cumulative Live Birth Rate of Patients with Poor Ovarian Response to the Patient-Oriented Strategies Encompassing Individualized Oocyte Number Criteria.

Objective: This study analyzed the role of traditional Chinese medicine (TCM) treatment on the cumulative live birth rate (CLBR) in women with poor ovarian response to the patient-oriented strategies encompassing individualized oocyte number (POSEIDON) criteria.
Methods: This cohort study selected 3347 patients with low ovarian response and divided them into four subgroups according to the POSEIDON criteria: Group 1 (n=947), Group 2 (n=778), Group 3 (n=164), and Group 4 (n=1458). Logistic regression analysis was used to evaluate the role of TCM treatment on the CLBR of patients with poor ovarian response to POSEIDON criteria.
A nomogram model to predict the high risk of lower live birth probability in young women undergoing the first IVF-ET cycle: a retrospective study.
Front Endocrinol (Lausanne)

Reproductive Medicine Center, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang, China.
Objective: To build a prediction nomogram for early prediction of live birth probabilities according to number of oocytes retrieved in women ≤ 35 years of age.
Methods: A prediction model was built including 9265 infertile women ≤ 35 years of age accepting their first ovum pick-up cycle from January 2018 to December 2022. Least absolute shrinkage and selection operator (LASSO) regression was performed to identify independent predictors and establish a nomogram to predict reproductive outcomes.
Comparison of fresh testicular sperm aspiration and use of either thawed pre-frozen sperm or oocyte freezing: impact on cumulative live birth rates for couples experiencing ejaculation failure.

Study Question: Is there a difference in the cumulative live birth rate (CLBR) after fresh testicular sperm aspiration (TESA) compared with the use of either pre-frozen sperm or oocyte freezing for couples experiencing ejaculation failure on the day of oocyte retrieval?
Summary Answer: After adjusting for confounding factors, the use of pre-frozen sperm or the freezing and thawing of oocytes appeared to be as effective as TESA in achieving CLBRs for couples experiencing temporary ejaculation failure.
What Is Known Already: Male patients may be concerned about experiencing temporary ejaculation failure on the day of their partner's oocyte retrieval, in which case they may choose surgical sperm retrieval, oocyte freezing on the day, or have their sperm frozen in advance. However, the clinical efficacy of these three options has not yet been evaluated.
