Do müllerian Anomalies Affect Embryo Implantation?

Status Completed

Clinical Trial Summary

Müllerian anomalies (MA) are associated with infertility and affect approximately 6.3% of the infertile population. The estimation of the frequency of MAs is not without controversy because it depends on the diagnostic method used and sometimes on the established diagnostic criteria. This pathology is associated with abortion during the second trimester in addition to other complications that include preterm labor, fetal malpositions and an increased rate of caesarean section, although some patients may remain asymptomatic. An association between MA and endometriosis has been described and in particular the case of the septum uterus, therefore it is difficult to establish whether the reproductive results of women with MA tdepend only on the uterine factor or also on the quality of the oocytes.

Clinical Trial Description

The main reproductive problems associated with these malformations include, abortion , recurrent abortion ectopic pregnancy and preterm delivery . The experience gained from oocyte donation shows that these women are pregnant less, even with the transfer of good quality embryos. The hypothesis of this poor uterine receptivity is in the poor endometrial vascularization that can decrease embryo implantation. The reason for infertility in women with AM includes decreased muscle mass, decreased endometrial vascularization, decreased capacity of the endometrial cavity, less receptive areas (septum). The lower fertility observed in some women with Müllerian malformations has been partially explained by its tubal factor and its association with endometriosis, with a higher prevalence in them, compared to patients without malformations.

Studies have confirmed an irregular differentiation and estrogenic maturation of the endometrium lining the uterine septum or its internal structure, which has less presence of connective tissue and more muscle mass. Given the confusion generated if the unfavorable reproductive result is due to oocyte quality or endometrial receptivity, it is necessary to use a model that guarantees oocyte / embryo quality and this is offered by oocyte donation. The aim is to evaluate the implantation rate in women with MA who receive donated oocytes compared to women without MA. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
