Active clinical trials for "Infertility"

Influence of inguinal hernia repair on sperm autoimmunity using MAR test

This is a retrospective single center analysis which includes all the fresh, IOC (insemination of in vitro matured oocytes) and frozen embryo transfer (ET) performed between January 2000 and December 2019 at Humanitas Fertility Center after IVF-ICSI (In Vitro Fertilization - Intracytoplasmic Sperm Injection) cycles. The primary objective is to determine the impact of the biologist performing the embryo transfer on the pregnancy probability, in terms of ongoing pregnancy rate (OPR), defined as the number of viable pregnancies that had completed at least 12 weeks of gestation on the total number of ET performed. Secondary end point is to evaluate whether the biologists improve their performances as their experience increases, allowing the drawing of an ET learning curve in term of pregnancies for the different biologists. The biologist's experience was assessed in terms of number of previous interventions performed prior to the day of ET. A total of 28 operators were eligible to participate in the study. Any biologists who performed less than 100 ETs was excluded from the analysis.

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.

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.

The investigators retrospectively analysed the maternal and neonatal outcomes following a single fresh blastocyst transfer and a single warmed blastocyst transfer from procedures performed between 2014 and 2018 in a tertiary level university based fertility clinic.

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

High follicular fluid amyloid A level is associated with reduced pregnancy rate. The aim of this study was to find an association between serum level of amyloid A and unexplained infertility.

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.

Several studies had analyzed the correlation between embryo transfer operator experience and implantation, clinical pregnancy, abortion and delivery rate. The aim of the present study is determining if the probabilities of embryo implantation and pregnancy are associated to the operator performing the embryo transfer. This study allows following more than 30 different operators in a global period of 20 years with almost 20,000 procedures.

Objective: To investigate the correlation between total and bioavailable serum 25-OH vitamin D, ovarian reserve and ovarian response to controlled stimulation in egg donors.
