Active clinical trials for "Infertility, Female"

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.

The purpose of this study is to find out more about tests used to estimate the number of eggs a woman has remaining in her ovaries (her 'ovarian reserve'). It is thought that women who have a greater number of eggs or ovarian reserve may have a better chance of successful in vitro Fertilisation (IVF) treatment than those who have a smaller number of eggs. Accurately predicting the likely outcomes of IVF would be of great benefit for counselling patients before they go through expensive and demanding treatments such as IVF and IVF with Intracytoplasmic sperm injection (IVFICSI). Over the past two decades, many endocrine and ultrasound markers have been designed and are now used as indicators of ovarian reserve. A number of screening tests are utilized to measure these markers, either by ultrasound scanning techniques or taking blood samples. However it is not yet known which, if any, best predict the outcome of IVF treatment. We would like to investigate these various measures of ovarian reserve to determine which are most accurate, particularly for predicting live birth rates, as up to now only poor to moderate quality evidence has been available for this outcome. This will be a prospective cohort study of 300 women who already intend to undergo IVF/IVF-ICSI treatment. Study participants will have one extra blood sample and ultrasound examination, for the purposes of measuring markers of their ovarian reserve, at the start of their IVF/IVFICSI treatment cycle. No other interventions will be required and their treatment cycle will not be affected by their participation in the study.

Although Caesarean section (CS) is often a necessary surgical intervention, it may also be associated with an increased risk of short- and long-term sequelae. It was thought that CS may increase the risk of female subfertility or even infertility. In assisted reproductive technology (ART) cycles, the process of implantation is believed to be the most important factor in determining pregnancy outcome. In view of conflicting results on the influence of a previous CS on outcomes of ART, this study will be conducted to investigate the impact of the mode of previous delivery on ICSI outcomes.

To determine whether there is higher incidence of skewed X chromosome inactivation(SXCI) in the recurrent miscarriage(RM) population compared with normal population, and verify the existing hypothesis of the possible genetic mechanisms underlying the association between SXCI and RM.

Previous studies in animal model showed clearly that lipid homeostasis influence oocyte meiosis resumption. However Liver X Receptors pathway has never been investigated in human ovocyte

Oocyte maturation requires a lot of energy, which is provided by the mitochondria via the synthesis of ATP. The majority of patients with advanced maternal age (AMA) have poor egg quality. One of the reasons depends on oxidative phosphorylation of Pyruvate to undergo maturation; on the contrary, the cells of the cumulus (CC) show great activity glycolytic so that these cells are able to provide ATP(adenosine triphosphate and energy substrates to the oocyte. The goal of this work is to analyze the mitochondrial function and energy production in oocyte donors compared with a group of women of advanced maternal age subject to a same ovarian stimulation Protocol

The purpose of this study is to comprehensively evaluate the transcriptomic signal of the endometrium before, during, and after the window of receptivity.

Uterine septum is the most common congenital uterine malformation. It accounts for approximately 35% of all uterine malformations, while the frequency of uterine malformations in the general fertile population is estimated to be between 1% and 4%. The presence of a uterine septum is associated with subfertility and a high incidence of obstetric complications, such as spontaneous abortion, 3-fold increase in preterm premature rupture of the membranes (PROM), 6-fold increase in preterm delivery, malpresentation at delivery, caesarean section, and increased perinatal morbidity and mortality. Some studies have found that surgical resection of the uterine septum improves pregnancy outcomes and significantly reduces the risk of preterm delivery. Therefore, the risk for a short-term adverse outcome and long-term sequelae due to preterm delivery such as intraventricular hemorrhage, necrotizing enterocolitis, sepsis, patent ductus arteriosus, retinopathy, deafness, chronic lung disease, cerebral palsy, perinatal death, and impaired mental development in women with uterine septum could be lowered by performing a relatively simple and safe hysteroscopic septum resection (HSR). However, there are two major concerns regarding HSR: cervical incompetence due to excessive dilatation during hysteroscopy and the rare yet serious complication of uterine rupture in subsequent pregnancy or delivery. Considering these elements, the aim of this study will be to evaluate the rate of preterm delivery in singleton pregnancy comparing primary infertile women who underwent HSR and who did not undergo the same procedure, with our without in vitro fertilization.

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.

To assess live birth after embryo transfer according to an individual's ERA results as opposed to routine protocol for frozen embryo transfer (FET) cycles.
