Omics in Reproductive Medicine: Application of Novel Technologies to Improve the IVF Success Rate

In vitro fertilization and andrology laboratory in 2030: expert visions

The aim of this article is to gather 9 thought leaders and their team members to present their ideas about the future of in vitro fertilization and the andrology laboratory. Although we have seen much progress and innovation in the laboratory over the years, there is still much to come, and this article looks at what these leaders think will be important in the future development of technology and processes in the laboratory.

Confirmation of the cardiac safety of nolasiban in a randomised cohort of healthy female volunteers

Nolasiban is an orally active oxytocin receptor antagonist being developed to increase the efficiency of assisted reproductive technologies. This study evaluated the pharmacokinetics, pharmacodynamics, and cardiac safety of nolasiban in 45 healthy women of child-bearing age. Nolasiban was administered in a fasted state with a standardised lunch served 4.5 h post-dose. Concentration-effect modelling was used to assess the effect of two dosages of nolasiban (900 mg and 1800 mg) on QTc following single-dose administration. We found no significant change in QTc at all tested dosages. Two-sided 90% confidence intervals of geometric mean C_max for estimated QTc effects of nolasiban were below the threshold of regulatory concern. The sensitivity of the assay to detect small changes in QTc was confirmed by a significant shortening of QTc between 2 and 4 h after consumption of a meal, which served to validate the model. Independent of the nolasiban assessment, this study also explored the effects of sex hormones on ECG parameters, especially QT subintervals. We found a significant relationship between JTpc and oestradiol. Heart rate was negatively correlated with progesterone. This study confirms the cardiovascular safety of nolasiban and describes relationships of sex hormones and ECG parameters.

Influence of age, stigma and social support on male temporary ejaculation failure on IVF oocyte retrieval day

OBJECTIVE

To explore the social and psychological factors associated with male Temporary Ejaculation Failure (TEF) during In Vitro Fertilization (IVF), with the goal of providing a theoretical basis for clinical intervention and treatment.

METHODS

The study included 75 TEF patients and 223 non-TEF patients undergoing IVF treatment at the center of reproduction and genetics of Integrated Chinese and Western medicine in the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from May 2019 to May 2020. A questionnaire survey was then administered to the study subjects. The questionnaires included general information, Perceived Stress Scale (PSS), Stigma Questionnaire, Perceived Social Support Scale (PSSS), and Positive Psychological Capital Questionnaire (PPQ). Logistic regression analysis was then used to analyze the social psychological factors associated with the research objectives.

RESULTS

Comparison of social demographic factors and clinical data between TEF group and non-TEF group: there were significant differences in the age and educational level between the two groups (P< 0.05), and the average age of the TEF group (37.01±7.11) was significantly higher than that of the non-TEF group (34.89±6.24). In addition, patients with high school or technical secondary school education levels had the lowest probability of TEF(X²=7.662, P=0.022). 2. The difference of related social and psychological factors between the two groups: the scores of perceived stress (17.57±6.51) and stigma (4.52±3.87) in the TEF group were significantly higher than those in the non-TEF group, which were (15.50±5.00, P< 0.05) and (2.61±3.52, P< 0.05), respectively. On the other hand, the scores of social support (55.31±14.04) and psychological capital (121.73±25.93) in the TEF group were significantly lower than those in the non-TEF group, which were (60.74±10.93, P< 0.05) and (130.31±17.32, P< 0.05), respectively. Results Obtained after conducting univariate logistic regression analysis indicated that age (OR=1.051, P=0.016), perceived stress (OR=1.073, P=0.005), stigma (OR=1.139, P< 0.001), family support (OR=0.901, P< 0.001), friend support (OR=0.932, P=0.023), other support (OR=0.915, P=0.004), self-efficacy (OR=0.947, P=0.009), resilience (OR=0.947, P=0.013), hope (OR=0.930, P=0.002), and optimism (OR=0.953, P=0.032) can all significantly affect male TEF.4. Moreover, the multivariate logistic regression analysis results indicated that age (OR=1.071, P=0.002) and stigma (OR=1.132, P=0.003) can positively predict TEF, while family support (OR=0.877, P=0.012) can negatively predict TEF.

CONCLUSIONS

The results obtained in this study have indicated that age and stigma are independent risk factors for male TEF, while family support is a protective factor of TEF. Analyzing the treatment of TEF from a socio-psychological perspective provides a new intervention target for effectively reducing its incidence, thereby helping to improve the success rate of IVF.
