ABSTRACT

Objective. The present work pretends to demonstrate the importance of the endometrium in the embryonic implantation and, as a consequence, elevate the pregnancy rates. Introduction. It is important to remark the role the endometrial epithelium has in the embryonic implantation; this must give protection against the pathogens than can enter into the endometrial cavity, as well as to permit and facilitate the implantation. Material and methods. In the Human Fertility Center we have been studying and treating 56 patients between January and June 2004, in these they have been carried out a total of 98 cycles, which have been concluded by different procedures of assisted reproduction of low complexity (intrauterine insemination). The first group of patients (n = 26) were the ones that had intrauterine insemination with a donor sperm (heterologus). The second group was conformed by patients that will be treated with homologus intrauterine insemination (spouse or partner), this group was composed by (n = 18) patients. On the third one, we group together those that didn’t need an assisted procedure, being these couples the ones that would conclude the treatment with programmed coitus, it was represented by (n = 12) patients. Results. For the first case, we treated 26 patients, in which were made 45 cycles obtaining a successful rate of 11.11%; for the second group, that is couples that would have as an option the intrauterine insemination with a previously capacitated sperm (homologus insemination), there were treated 18 cases with 24 stimulation cycles, achieving a pregnancy rate of 4.16%; in the last group there were 12 patients treated with 18 stimulation cycles, obtaining result rates of 11.11%. Discussion. The endometrial measure is fundamental because, as we know and have proven, the pregnancy rate made in this work has a direct relation with the endometrial thickness; we demonstrated that in the achieved pregnancies, all of them, the endometrium had diameters larger than 11 mm.
