Active clinical trials for "Infertility"

The study was conducted to assess the impact of two doses of coenzyme Q10 on seminal fluid parameters and antioxidant status in infertile men.

The main outcome measures are the number of dominant follicles (≥13 mm) on the day of hCG trigger and the number of mature (MII) oocytes collected after conventional versus delayed-start ovarian stimulation protocol. Secondary outcome measures are including total number of oocytes retrieved, oocyte maturity rate (number of MII oocytes/total number of oocytes), oocyte yield (total number of oocytes retrieved/ antral follicle count [AFC]), mature oocyte yield (number of mature oocytes retrieved/AFC), total dosage of gonadotropin (recombinant FSH and/or highly purified hMG) needed, number of days needed for ovarian stimulation, quality of obtained embryos, fertilization rate (the proportion of total number of two-pronuclear [2PN] stage zygotes /per total injected MII oocytes), implantation rate (total number of observed gestational sac/ number of transferred embryos) and clinical pregnancy rate (presence of fetal heart beat by transvaginal ultrasound per embryo transfer).

patients with previous failed ART cycles with high peripheral NK cells will be divided into 2 groups: one group of patients with previous failed ART cyles will undergo standard treatment but the other group will have in addition lipid emulsion &prednisolone & LMWH

A randomised controlled open-label clinical trial to compare the outcome parameters after ovarian stimulation using recombinant-human FSH (follicle stimulating hormone), starting on day 2 of the cycle versus start in the late follicular phase of the cycle.

The aim of the work is to determine whether the use of immunomodulatory drugs could improve the reproductive of outcome of infertile patients who have autoimmune thyroiditis with positive autoimmune antibodies undergoing IVF-ET.

2groups with peritoneal adhesions after cesarean delivery will be allocated to either laparoscopic tubal adhesiolysis or to IVF/ICSI

In the early stages of assisted reproductive technologies (ART), oocyte retrieval was performed via laparoscopy, a cumbersome and expensive process requiring general anesthesia. Today, transvaginal oocyte retrieval for ART is a routine procedure performed under ultrasound guidance. Double-lumen retrieval needles, which are capable of flushing ovarian follicles, were developed to overcome the possibility of oocyte retention within the ovarian follicles and retrieval collection system. Single lumen needles have been introduced and are routinely used by most groups due to their supposed ability to retrieve the same number of oocytes in a shorter operation time.

The objective of this study was to evaluate the outcome of follicle stimulating hormone (FSH) co-administration with human chorionic gonadotrophins trigger for women with unexplained infertility (UEI) and assigned for letrozole (LTZ) stimulated intrauterine insemination (IUI) cycles .

According to the WHO, infertility affects 15% of reproductive age couples worldwide. Among the assisted reproductive technologies available for patients with infertility, intracytoplasmic sperm injection (ICSI) has become one of the most widely employed and is now thought to be the most common method for oocyte insemination outside of the human body. ICSI entails the selection of an individual sperm cell and its injection directly into an oocyte. Usually, an embryologist performs the selection of the individual sperm cell to inject by subjectively observing the morphology and progression of the candidate spermatozoon. Subjectivity and time constrains, however, suggest the best possible candidate might not always be selected. Further optimization of ICSI technology remains a significant goal, yet the majority of approaches proposed in the literature have returned mixed results. The deployment of an artificial intelligence (AI) software capable of detecting and non-invasively predicting the value of individual spermatozoa in real time could significantly improve ICSI. SiD (IVF 2.0 Ltd, London, UK) is a software designed to identify, evaluate, and assist in the spermatozoon selection process ahead of ICSI. SID uses a mathematical model to evaluate individual spermatozoa in real-time according to their motility patterns (for instance velocity, linearity, straightness) and their morphology. The software has been developed by making use of retrospective data analysis, but its prospective evaluation is still pending. With the above in mind, this study intends to address the following question: can the use of a software assistant for the selection of individual sperm cells for injection (SiD), improve ICSI outcomes (oocyte fertilization, embryo development and quality, embryo ploidy, pregnancy, and live birth)? Patients with a clinical indication for undergoing ICSI will be prospectively enrolled into the study. Following ovarian stimulation, the oocytes retrieved from each patient will be randomly split into two groups and inseminated by ICSI using sperm selected either subjectively by an embryologist (control group) or by the software assistant SiD (experimental group). Embryos will be allowed to develop for up to six days and until blastocyst formation assessments are completed. Embryos might be subjected to cytogenetic screening or used for embryo transfer according to patient needs. The recorded outcomes will be anonymized prior to statistical analysis.

Follitropin delta is a rFSH, uniquely expressed in a human fetal retinal cell line, which owing to differences in glycosylation profile has a lower clearance and induces a higher ovarian response in humans than existing rFSH preparations when administered at equal doses of biological activity. A noninferiority clinical trial (ESTHER-1) in which individualized dosage of follitropin delta according to each patient's profile (AMH and weight) was compared to conventional follitropin alfa dosing for IVF have demonstrated that an individualized follitropin delta dosing is noninferior to conventional follitropin alfa with respect to ongoing pregnancy rate, ongoing implantation rate, and also live births, with a concomitant reduction in iatrogenic complications, including OHSS
