Active clinical trials for "Infertility"

The investigators will investigate the effect of antioxidants and lifestyle factors on the level of oxidative stress. As oxidative stress cannot be directly measured, it will be approximated by the DNA fragmentation index (DFI) which reflects the level of DNA damage in sperm caused by oxidative stress.

The ENDALGOFIV study of pain assessment during the IVF pathway at Lille University Hospital, conducted from November 2018 to July 2020, showed that endometriosis patients have intense pain, particularly of a neuropathic nature, even before starting their IVF pathway compared to patients without endometriosis, but without an increase in pain scores during the IVF pathway. As a result of this study, a new pain management protocol for all patients undergoing IVF have been implemented in our MPA center. The study will be evaluated the impact of this new management. Main objective To evaluate the effect of the change in pain management protocol in all patients (endometriotic or not) undergoing IVF treatment during the study period by comparing them to the data of the ENDALGOFIV 1 study.

Adverse childhood experiences can have powerful effects on health and quality of life in adulthood. Thus, having a history of childhood trauma, before the age of 18 (physical aggression, sexual abuse, death of a close person, etc.) significantly increases the risk of having cancer, cardiovascular disease, psychological damage , or earlier mortality. Validated scores allow the evaluation of the importance of adverse childhood experiences, in particular the ACE score (adverse childhood experiences) published by Felitti. Studies on the subject show a dose-response relationship between exposure to adverse childhood experiences and negative outcomes in terms of health and well-being. The physiopathological tracks to explain the occurrence of somatic pathologies in adulthood include the observation of a state of hyper-activation of the HPA axis that persists in adulthood; modulations of immunity, but also epigenetic modifications. Some data are available on the associations between childhood trauma and obstetric risks, with a significant increase in the risk of preterm delivery and fetal death in utero. Primary objective : 1a) To study the prevalence of adverse childhood experiences (ACE) in women consulting for the first time in an PMA service for the desire to become pregnant, and 1b) To study the association between adverse childhood experiences and infertility in adulthood, by comparing infertile women with nulliparous control women in the general population consulting for their classic gynecological follow-up.

The goal of this study is to compare the difference in clinical pregnancy, miscarriage and livebirth rate between day 6 euploid blastocyst transfer on the 6th and the 7th day of progesterone exposure in Hormonal Replacement Therapy (HRT) FET cycles. This prospective & randomized study will only include euploid day 6 blastocysts. This will be the first prospective study of euploid day 6 blastocysts thereby excluding aneuploidy as a cause of miscarriage and implantation failure. The point of randomization will occur on the day of progesterone commencement.

On the basis of the current study, amlodipine seems to be a promising drug on improving uterine, ovarian blood flow, size of pre-ovulatory follicle, midluteal progesterone level and pregnancy outcome in patients with pco.

The objective of this study is to determine the effect of Bemiparin, a low molecular weight heparin, on implantation rate in women with unexplained recurrent implantation failure undergoing IVF/ICSI treatment.

The investigators aimed to investigate the effects of salpingectomy and Methotrexate administration on ovarian reserve in ectopic pregnancy.

This study is a prospective before & after clinical trial to investigate the efficacy of double stimulations during both the follicular and luteal phases in patients with poor ovarian response undergoing IVF and intracytoplasmic sperm injection (ICSI) cycles. The study protocol is approved by the Ethics Committee (Institutional Review Board) of Royan institute. The study is conducted according to the Declaration of Helsinki for medical research. All participants provide informed consent after counseling for infertility treatments and routine IVF/ICSI programs. All the patients who diagnosed as poor ovarian responders (POR) based on the Bologna criteria are eligible for participation in this study. In order to define the poor response in IVF, at least two of the following three features must be present: (i) advanced maternal age or any other risk factor for POR; (ii) a previous POR; and (iii) an abnormal ovarian reserve test (ORT). Two episodes of POR after maximal stimulation are sufficient to define a patient as poor responder in the absence of advanced maternal age or abnormal ORT. Stage one of treatment protocol First stimulation performs by Clomiphene citrate (Ovumid®, Iran Hormones Company) 25 mg/day with co-treatment of Letrozole (Letrofem®, Iran Hormones Company) 2.5 mg/day are given from cycle day 3 onwards. Letrozole is only given for 4 days and clomiphene citrate is continuously used before the trigger day. Patients start to inject human menopausal gonadotrophin (HMG) (Menopur®, Ferring, Switzerland) 150 IU every other day beginning on cycle day 6. When one or two dominant follicles (18 mm in diameter) observed, the final stage of oocyte maturation will be induced with triptorelin 100 μg (Decapeptyl®; Ferring GmbH, Germany) follows by ibuprofen 600 mg (Ibuprofen-Najo® , Coated Tablets, Najo Company, Iran) is used on the day of oocyte maturation triggering and the day after. After the first oocyte retrieval, human menopausal gonadotrophin and letrozole are administrated to stimulate follicle development, and oocyte retrieval will be carried out a second time when dominant follicles have matured. All highest-quality embryos (including grade 1 and grade 2, eight-cell blastomere embryos) will be cryopreserved by vitrification method on the third day after oocyte retrieval. Stage two of treatment protocol: Transvaginal ultrasound evaluation performs after oocyte retrieval to determine whether to continue the second ovarian stimulation. The criterion for continued stimulation is the presence of at least two antral follicles 2-8 mm in diameter. A total of 225 IU HMG (Menopur®, Ferring, Switzerland) and letrozole 2.5 mg (Letrofem®, Iran Hormones Company) is administered daily from the day of, or the day after, oocyte retrieval. The initial second stage follicular monitoring is conducted 5-7 days later, and then for follow up every 2-4 days, by using a transvaginal ultrasound evaluation, to record the number of developing follicles. Letrozole administration is discontinued when the dominant follicles reached diameters of 12 mm, given that large follicles have redundant LH and FSH receptors, and good response to exogenous hormone stimulations. Daily administration of medroxyprogesterone acetate 10 mg (Progestrone®, 5mg bid; Aboureihan, Iran) is added beginning on stimulation day 12 for cases in which post-ovulation follicle size is smaller than 14 mm in diameter and stimulation needed to continue for several more days. This performs to postpone menstruation and avoid oocyte retrieval during menstruation, to prevent the risk of infection from the procedure. When three dominant follicles reached diameters of 18 mm or one mature dominant follicle exceeded 20 mm, the final stage of oocyte maturation is induced again with triptorelin 100 μg (Decapeptyl®; Ferring GmbH, Germany) by injection. Again, ibuprofen 600 mg (Ibuprofen-Najo® , Coated Tablets, Najo Company, Iran) is used on the day of oocyte maturation triggering and the day after. Transvaginal ultrasound-guided oocyte retrieval was conducted 32-36 h after GnRH agonist administration. All retrieved oocytes were treated same as in the study stage one.

Serum concentrations of the different hormones involved in follicular steroid genesis during a cycle of controlled ovarian stimulation with recombinant FSH or HMG will be compared in this study. Serum Progesterone (P) levels at the end of Controlled Ovarian Stimulation (i.e. the day of triggering) have been related to cycle outcome, in terms of ongoing pregnancy and live birth rates. Large cohort studies show that P levels above a certain threshold are associated with poorer cycle outcome. The mechanisms behind P elevation are not well understood yet. It has been shown that P levels are positively related to ovarian response and to the dose of FSH given during COS. Furthermore, it has been well documented that P levels at the end of stimulation are significantly higher when recombinant (r) FSH is used for COS when compared to HMG, either in a GnRH agonist long protocol or in a GnRH antagonist protocol. Some authors suggest that this finding is explained by the fact that COS with rFSH provides a higher oocyte yield than when hMG is given, so the higher P levels observed would be explained by the larger number of follicles developed when rFSH is used. On the other hand, other authors explain this event by a different follicular esteroidogenesis when HMG is used for COS compared to rFSH The hypotheisis behind this assumption is that rFSH enhances P synthesis from its precursor pregnenolone in the granulosa cells. This P is unable to be further metabolized into androgens because of the lack of 17-20 lyase in the human granulosa cells, and therefore is delivered into circulation. On the other hand, when HMG is given for COS, the ∆4 pathway is promoted, and pregnenolone will be catabolized in to Dehidroepiandrostenodione (DHEA), in the theca cells, and this one to Androstenodione, which will be finally aromatized in to estrogens. This mechanism will explain the lower P and higher E2 levels observed in HMG cycles in comparison to rFSH cycles.

This is an open-label, Phase 3, randomized, two arms, multicenter, prospective, experimental study of Folitime® (a new biosimilar formulation of r-hFSH, follitropin alfa) versus the original one (Gonal-f ®).
