Non-urgent medical care, such as fertility treatments, has been massively postponed during the past weeks due to the COVID19 pandemic. The lockdown and the closure of IVF centers might cause anxiety and depression among infertile couples, who are already exposed to the distressing experience of infertility and for whom the wait for a baby already appears unending. Few data are available regarding the impact of SARS-CoV-2 on pregnant women and foetus, or on fertility. This study aims to assess the views of infertile couple regarding the potential risks of COVID during their fertility treatment and their personal experience of the COVID pandemic and their expectation for further treatment .
The COVID-19 pandemic brought new challenges to our nationwide healthcare system, with rapid escalation of the number of affected individuals over a handful of weeks. From March 13, a first set of measures was taken to minimise the spread of the virus, which largely impacted societal and economical daily life. A view days later, on March 17, the country was put in "lockdown" and all non-urgent medical treatments were cancelled or postponed. As recommended by the major scientific fertility societies, all non-ivf fertility treatments were discontinued abruptly, whereas started ivf stimulations were continued until oocyte aspiration, where after a freeze-all strategy was applied. There is little information available for women aiming for pregnancy or embarking on assisted conception. Given the modelling of the pandemic, including the time to peak and subsequent tail, considerable delays in conception to substantially attenuate risk may be required, which will inevitably impact patients wellbeing and overall success rates. A questionnaire was developed to explore patients perspectives on different aspects of their fertility treatment during the COVID-19 pandemic. The questionnaire contains the following sections: - demographic variables; - questions regarding the fertility history of the respondent; - questions regarding the impact of fertility treatment cancellation / postponing fertility treatment during COVID-19 on their life, psychological wellbeing and relationship; - questions regarding continuing medical treatment on their own, or seeking treatment elsewhere; - questions regarding the satisfaction of measures taken by their fertility center regarding the COVID-19 pandemic; - questions regarding expectations of further treatments, with focus on safety issues related to the COVID-19 pandemic. Eligible patients will be selected electronically from our database and digital agenda. After selection, patients will be contacted via email to participate. Two reminders will be send in case the questionnaire is not filled out: a first reminder after one week, a second reminder after two weeks.
Infertility is a severely distressing experience for many couples. Depression and anxiety are psychological disorders associated with infertility, and they may worsen during infertility treatments. This study times to understand the changes in the psychological status of infertile patients who had in vitro fertilization (IVF) treatment interrupted or postponed because of the COVID-19 pandemic.
This study determines the effectiveness of clay-based group study on the loneliness and hopelessness levels in elderly living alone. For this, while the experimental group will six 1,5 h weekly of clay-based group study and interviewed face-to-face twice, the control group will interview face-to-face twice
Investigators will evaluate and compare the efficacy of Sitagliptin/Metformin to metformin and sitagliptin on gdf9 and bmp15 gene expression on PCOS patients undergoing intracytoplasmic sperm injection(ICSI).
The use of machine learning techniques using an artificial intelligence tool is proposed to analyze clinical data to predict best possible IVF/ART outcomes. This tool has been utilized to accurately predict embryo quality here at Cornell. Utilizing this tool to assess objective clinical findings and predict outcomes of assisted reproductive techniques is sought, with the ultimate goal of an automated tool to reduce implicit physician bias. Within this goal, using this tool to objectively and accurately assess baseline ovarian reserve at the start of an ART cycle is proposed, using 3D sonography to image the ovary and artificial intelligence tool to objectively identify baseline antral follicle counts.
The association between serum progesterone (P) levels, measured on the day of ovulation trigger, and the outcome of in vitro fertilization cycles, has been one of the major controversies in the field of ovarian stimulation endocrinology. This is a single-center retrospective cohort study. Study duration period is from January 2012 to December 2016. All fresh embryo transfer (ET) both at cleavage stage and blastocyst stage, performed in Humanitas Fertility Center during the study period, were included.
During assisted reproduction technology treatments like in vitro fertilization, some patients give a poor ovarian response to controlled ovarian hyperstimulation. The European Society of Human Reproduction and Embryology consensus defined poor response to ovarian stimulation during in vitro fertilization with Bologna criteria. Bologna criteria: At least two of the following three features must be present: (i) Advanced maternal age (≥40 years). (ii) Previous Poor responders (≤3 oocytes with a conventional stimulation protocol). (iii) An abnormal ovarian reserve test Most controlled ovarian hyperstimulation regimens currently used for expected poor responders are based on using a high daily dose (300- 450 IU/day) of exogenous gonadotropins. Giving a high gonadotropin dose obviously increases the cost of in vitro fertilization, a consequence that would be acceptable if paralleled by an improvement in in vitro fertilization outcome. Unfortunately, however, the available data suggest that increasing the daily gonadotropins dose may increase the number of retrieved oocytes, but not the final success rate of in vitro fertilization.
The study seeks to understand how anti-HIV drug Biktarvy, which contains the drugs tenofovir alafenamide (TAF), emtricitabine (FTC), and bictegravir (BIC) is absorbed and how long it persists in different body compartments, including mucosal tissues, as it may be considered for PrEP or PEP regimens in the future.
