BACKGROUND: In 1978 the first successfull birth by in vitro fertilization took place and this assisted reproduction technique became alternative of treatment in the couples with infertility that had not obtained pregnancy with conventional treatments. The conditions of clinical treatment and laboratory improved, which were in greater number of pregnancies. In 1985 the first study was published that showed adverse perinatal results in pregnancies obtained with fertilization in vitro. Some researchers attributed these results to the increase in the number of multiple pregnancies, pregnant patients older than 35 years, and to the antecedents of infertility...

UNLABELLED: The evaluation of ovarian reserve in regard to the exogenous response elicited by gonadotropines is directly related to the interconnection of diverse intrafollicular factors involved in ovum components, and thus, to a better embryonic development, which will be reflected in the pregnancy ratios of assisted reproduction programs. A series of markers have been proposed in order to dynamically evaluate the ovarian response: hormone determinations (FSH, E2, FSH:LH index), biochemical factors (inhibine-B), intrafolicular (cytokines, leptin), neuromodulators (GNRH test), and so forth...

The advantages of cultivating human pre-embryos to the stage of blastocites, are well known. The use of media of culture sequential, without the backing of somatic cells, is new. The objective was to cultivate human pre-embryos to the stage of blastocyte to the determine the recuperation indexes, implantation index and pregnancy index in patients subjected to FIVT/TE or ICSI. Once obtained the ovules of patients were injected/inseminated to latter be cultivated for 72 hours using P1 medium at 10% of SSS under mineral oil for, latter, be transferred to a complex medium for blastocites culture for 48 hours, and finally be transferred...

Deep venous thrombosis is an uncommon but feared complication in pregnancy. The treatment of choice in most centers is heparin and compression stockings, which effectively prevents pulmonary embolism, but the incidence of chronic venous insufficiency with skin change and ulcers after such treatment is reported to be up to 65%. In the period 1985-93, thirty-nine pregnant women were treated for femoroiliacal venous thrombosis (FIVT) with operative thrombectomy, arteriovenous fistula and anticoagulant therapy...

Endometriosis is an ailment which has no exact etiology due to its uncertain genesis, its inception can develop unnoticed, its silent evolution makes it difficult to identify it until a cardinal symptom appears and its semeiology provides us facts to integrate a diagnosis, it is an entity that does not have relation while and/or with the reproductive stage, neither with the parity, but we are aware it occurs in its different stages, varying from 9% to 33% in the reproductive cycle, it can be recurring after being medically or surgically treated, appearing endometriomas in it or in the infundibulum stump in the latter case...

From the first publications about fertilization in vitro (FIVTE) Patrick Steptoe and Robert Edwards, added several knowledges and new concepts in modern Gynecology, so starting a new era of Reproductive Medicine, so ideating a series of programs and methodologies to emulate the physiological ovarian cycle; with this concept Ricardo Asch carries the transference of gametes to tubes and calling this procedure GIFT. These methodologies with a high technology have been called Assisted Reproduction, which is reviewed in this paper...

The "mouse test" resulted to be an indispensable requisite in order to do, with security, although not complete, the serum selection, to use in the extracorporal phase of FIVTE. Because of the observations it is considered that it should be tried to addition the culture medium with good quality sera; which is evident with a 90% rate, or more, of segmentation in the embryonic system of mouse, of two cells.

It is a retrospective and transverse study with an analysis of results from patients submitted to intrauterine insemination (IIU), intratubal gamete transfer (GIFT) and in vitro fertilization and embryo transfer (FIVTE), at the Clinic of Assisted Reproduction, Instituto Nacional de Perinatología in Mexico City. From 134 cycles of patients submitted to IIU, 113 corresponded to women with diagnosis of sterility from non determined cause, and 21 to cases with endometriosis, and at least one permeable tube. From the first group, 22 pregnancies were obtained, for a monthly fertility rate of 19...

This study shows that there is certain tendency to asssign more value to the observation of follicular growth by ultrasound than to hormonal levels "per se". However, the appreciation of growth is only part of the phenomenon of development and ovarian maturity, for that, surveillance with hormonal monitor of ovarian response keeps with a most important role in Assisted Reproduction Clinica. The basal levels, mainly of FSH and in a less degree LH, inversely correlate with the amount of retrieved ovocytes. Estradiol values should be interpreted with a fixed point of reference, as the day of HCG administration, and a direct relation is seen between estradiol levels and captured ovocytes; however, is of highest usefulness to value the conduct of estradiol level, with the knowledge that the prognosis for good capture rates improves with ascending values and above 700 pg in the day of HCG administration...
