Active clinical trials for "Infertility"

To investigate, whether on the day of egg retrieval, after ovarian stimulation for ICSI (intracytoplasmic sperm injection), there is a correlation between the intrafollicular AMH (Anti-Müllerian hormone) levels and the ploidy status of the blastocyst.

Male factor infertility is a leading cause of primary and secondary infertility. Poor sperm quality is defined as having an abnormal semen analysis. There are now options to assess sperm quality with at-home sperm analysis kits, including an FDA approved Yo Sperm kit (https://yospermtest.com/) which analyzes the motile sperm concentration [concentration (millions / ml) x motility (Percentage motile)] and sperm quality (YO Score) which compares your results to laboratory standards and to other men who have fathered children. The effects of supplements (vitamins, minerals, and anti-oxidants) on improving sperm quality are still debated. Taking additional supplements to improve sperm quality represent a modifiable risk-factor that would be an easy intervention for patients struggling with male factor infertility. The life cycle of sperm production is estimated at 3 months, so any intervention would require a 3 month course to see its full effect. The investigators hypothesize that a 90 day course of the "Power Prenatal for Sperm", a male fertility supplement by Bird&Be (https://birdandbe.com/the-power-prenatal-for-sperm) will improve sperm quality (YO Score) after taking the supplements.

Patients with diminished ovarian reserve (DOR) who undergo in vitro fertilization and embryo transfer (IVF-ET) are included as the research subjects. The effects of Traditional Chinese Medicine (TCM) for kidney tonifying and blood circulation regulating of different intervention courses on ovarian hyporesponsiveness, IVF-ET outcome and clinical compliance in DOR patients are studied by a non-inferiority randomized controlled trial. The purpose is to identify the breakthrough point and treatment timing of TCM treatment, explore the best treatment course of TCM, and optimize the TCM therapeutic regimen.

Chronic endometritis (CE) is characterized by the presence of atypical plasma cell infiltrates (CD138 positive) in the endometrial stroma. Recent analyzes suggest that CE adversely affects fertility by reducing endometrial receptivity, impairing decidualization and uterine contractility, thus increasing the risk of recurrent pregnancy loss and implantation failure. It is likely that a significant proportion of idiopathic infertility cases are due to CE. The diagnosis of CE is a challenge because the clinical examination and transvaginal ultrasonography are considered non-specific. The recent scientific research has been aimed at identifying hysteroscopic CE diagnostic criteria and establishing the compatibility of ultrasonographic, hysteroscopic, histopathological (including the use of immunohistochemical testing with antibodies against human CD138) and microbiological diagnoses. Preliminary literature results suggested that successful treatment of CE with antibiotics could improve live birth rates.

To compare the difference in cumulative live birth rates within one year between double stimulations protocol and two-cycle antagonist protocol in poor ovarian responders.

Prospective cohort multicentric study including infertile patients undergoing a pregnancy test on βhCG day (around ET +11), after an ET in the context of an artificial cycle and receiving LPS with vaginal natural progesterone following the clinical practice in IVI RMA (Spain).

Poor ovarian responders (POR) include a significant proportion of women referred for IVF treatments (ranging from 9 to 24 %), most of whom are in late reproductive age. In fact the live birth rate in the entire POR category is poor (about 6 % per cycle). However patients <40 years have a significantly better prognosis compared to older patients, mainly due to better oocyte quality.Attempts to improve IVF cycle outcomes for poor responders included modifying the steps of ovarian stimulation protocols , such as different luteal phase pretreatments, increasing ovarian stimulation doses, as well as addition of various supplements. So far, most of the modifications had limited success, therefore, optimal protocol for poor responders has remained elusive. Final oocyte maturation trigger is one of the most important key success factors in assisted reproductive technologies (ARTs). Oocyte maturation refers to a release of meiotic arrest that allows oocytes to advance from prophase I to metaphase II of meiosis. Luteinizing Hormone (LH) surge by dismantling the gap junctions between granulosa cells and oocyte inhibits the flow of maturation inhibitory factors into ooplasm and causes drop in concentration of cAMP. Decreased concentration of cyclic AMP (cAMP) in turn increases concentration of Ca and maturation-promoting factor (MPF), which are essential for the resumption of meiosis in oocyte and disruption of oocyte-cumulus complex triggering follicular rupture and ovulation about 36 h the LH surge. The aim of the study is to compare the oocyte yield , oocyte quality and the ongoing pregnancy rate between dual trigger treatment (combination of gonadotrophin-releasing hormone (GnRH) agonist and human chorionic gonadotrophin) and human chorionic gonadotrophin alone in PORs undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) cycles using a GnRH-antagonist protocol.

How to improve the fertility of infertile women has become a hot topic in the field of assisted reproduction. Animal experiment has shown that RECO-18 significantly improved the female fertility in mice, and the specific mechanism was related to reducing follicular atresia, promoting follicle development and improving oocyte quality. Therefore the investigators aim to conduct a pilot study to explore the effect of RECO-18 in infertile women undergoing assisted reproduction treatment. This study is a prospective, randomized, controlled clinical study. The treatment group takes RECO-18 while the control group takes the multi-vitamins. The primary indicator is the ongoing pregnancy rate at 12 weeks' gestation; the secondary indicators are the number of oocytes retrieved, the normal fertilization rate and the rate of high quality embryos, implantation rate, clinical pregnancy rate, and early miscarriage rate.

In this prospective study, the possible effects of embryo viability and degree of blastocele re-expansion on pregnancy outcomes before vitrified/thawed blastocyst transfer will be evaluated.

The aim of this study will be to compare between 4 different induction protocols in women who: Failed to achieve ovulation after clomiphene citrate treatment at a dose of 150mg daily (if the patient can tolerate this dose) for 5 days for 3 cycles or only 100 mg daily for the same duration (if she can't tolerate higher dose) Failed to achieve pregnancy after 3 cycles of ultrasound indicated ovulation with clomiphene citrate treatment at a dose of 100mg or 150mg daily. All induction protocols will be carried out in non-IVF cycles, and continued for 3 cycles or until pregnancy whichever will be earlier.
