Filter by:For several years, the effects of environmental pollution on human health have been a growing concern for the scientific community and public authorities. Among the many known chemical contaminants, persistent organic pollutants (POPs) are of particular concern because of their properties as endocrine disrupters, bioaccumulation and biomagnification. The associations between environmental pollutants, endometriosis and infertility remains poorly understood. The objective of this exploratory non interventional monocentric study conducted in the University Hospital of Nantes, is to identify endogenous molecular profiles associated with endometriosis and related infertility. This project implements an exploratory approach combining exposure and metabolomics approaches based on high-resolution mass spectrometry to identify exposure and metabolomics profiles associated with infertility, and biomarkers for potential prognostic application.
The goal of this observational study is to learn about vaginal microbial characteristics in the patients under in vitro fertilization treatment. The study aims to address the following questions: (1) Is there any difference in microbial composition between the pregnancy and non-pregnancy groups? (2) Is there any differences in specific bacterial species between the two groups? (3) What are the favorable or unfavorable profiles of vaginal microbiota associated with achieving pregnancy? Patients will be asked to complete a questionnaire regarding their basic characteristics, and vaginal secretions will be collected via vaginal swab during frozen-blastocyst transfer procedures. The study will compare vaginal microbiota between pregnant and non-pregnant patients to assess its potential influence on clinical outcomes.
The goal of this study is to compare the cumulative pregnancy rates after 4 artificial inseminations with donor (IAD) in non-sterile women with plasma AMH levels > and < 1.1 ng/mL.
The goal of this observational study is to redefine an everyday clinical routine at the Humanitas Fertility center calculating the effects derived from the reduction of inappropriate and avoidable tests, procedures, tools and treatments currently used. Anonymized patients data about clinical procedures are used, taken from the internal database of the Humanitas fertility center
The goal of this monocentric retrospective observational study is to analyse, for the first time in literature, the role of the embryologist who freezes and thaws the embryos. The primary objective of the study is to understand whether the embryologist who freezes and thaws the embryo influences the CPR (clinical pregnancy rate). Secondary objectives, in case of statistically significant influence, are: - Evaluate who influences more the CPR, between the embryologist who freezes the embryos and the embryologist who thaws the embryos. - Evaluate if the embryologist who freezes and thaws the embryo impacts more than the embryologist or the physician who performs the ET. - Evaluate whether the embryologists improve their performances, as their experience increases. - Evaluate, through an external validation test, whether the model used can also be applied at other PMA centres The study will consider all the freezing (vitrifications) and thawing procedures, performed at Humanitas Fertility Center between January 2019 and June 2023. The study will include the transfers of single blastocysts, cryopreserved at Humanitas Fertility Center. On the other hand, the blastocysts transferred from other centres and the donor blastocysts will be excluded from the study, as well as multiple blastocysts transfers and the LP cycles. The embryologist's experience will be assessed in terms of number of previous cryopreservation (vitrification) and thawing procedures. We will include in the study all the embryologists who performed at least 50 freezing and thawing. For the evaluation of the study objectives, data will be gathered using a specific internal web-based database. The final model will be created by analysing the Humanitas Fertility Center dataset and validated using datasets extrapolated from similar population from the San Raffaele Hospital infertility centre
Infertility affects married adults, and In Vitro Fertilization (IVF) is an Assisted Reproductive Technology (ART) that can be treated. Women undergoing IVF are more likely to experience depression. There is a need to reduce depression by supporting and advising sufferers. The aim of this study is to evaluate pharmacist counseling's impact on pregnancy rates in depressed infertile females during IVF treatment.
The goal of this clinical trial is to investigate the impact of repeated antioxidant supplementation on blastocyst utilization and expansion rates in embryos under different oxygen concentrations. The study aims to answer the following main questions: - Does adding antioxidants every 12 hours to embryo culture media improve usable and expanded blastocyst utilization rates on days 5 and 6? - How are the O2 concentrations related to the effect of different methods of antioxidants supplementation on blastocysts utilization and expansion rates? Participants in this study are infertile couples undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. - Zygotes will be incubated at either 5% or 20% oxygen tension until the blastocyst stage. - Sibling zygotes will be divided into four groups: Group 1A and 1B: Antioxidants every 12 hours at either 5% or 20% O2 tension, respectively. Group 2A and 2B: Antioxidants only once at the beginning of embryo culture at either 5% or 20% O2 tension, respectively. Researchers will compare the four groups to determine if the repeated antioxidant supplementation of the culture media leads to improved blastocyst utilization and expansion rates compared to the baseline group.
The goal of this prospective cohort study is to learn about the overall and seasonal prevalence of vitamin D insufficiency and its determinants in a population of women with infertility who will go through in vitro fertilization in Sweden. The main questions it aims to answer are: - What is the prevalence of vitamin D insufficiency? - What are the determinants of this insufficiency? Participants will be asked to complete a questionnaire validated for dietary assessment of vitamin D intake and sun exposure habits and they will leave a blood sample for measurement of 25(OH)D concentration. Researchers will compare the in vitro fertilization outcomes between women with vitamin D insufficiency and sufficiency to see if there is any difference.
One hundred thirty women with unexplained infertility participated in a prospective clinical study. Patients were assigned at random to one of two groups. The first group (n=65) served as the study group and was given clomiphene citrate 50 mg (Tecnovula®, Techno Pharmaceuticals, Egypt) and sildenafil (Respatio®, Pharma right group, Egypt) 20 mg tablets. The second group (n=65) served as a control and received a placebo tablet in addition to the standard treatment of clomiphene citrate 50 mg (Tecnovula®). A transvaginal ultrasound was performed on all of the patients to assess ovulation.
. This study aimed to determine and compare the effect of vaginal sildenafil citrate and estradiol valerate on endometrial thickness, blood flow and pregnancy rates in infertile women.
