[Mexican National Consensus on Assisted Reproduction Treatment].

Background: It is estimated that 15% of couples living in industrialized countries are infertile, ie have failed to conceive, reproductive age, after 12 months ormore of regular intercourse without contraception. During the past decade has increased the demand for fertility treatments because they believe are moreeffective now.

Objective: To unify the therapeutic approach and service to patients and set a precedent for a Mexican Official Standard respect and support for the legislation of these procedures.

[Future reproductive ability in post-treatment Asherman's syndrome patients].

Background: Hysteroscopy is the best approach for the management of Asherman syndrome with reproductive purposes, since it allows a quick diagnosis and treatment of partial or total uterine adhesions. However, there are a few studies on the reproductive outcome in patients with Asherman's syndrome.

Objective: Evaluate the results of adherenciolisis hysteroscopy in women with Asherman's syndrome.

[Preliminary results of effectiveness of two schemes of controlled ovarian hyperstimulation protocols with recombinant foliculle stimulating hormone in intrauterine insemination cycles].

Background: The intrauterine insemination (IUI) is the first line treatment in different infertility situations.

Objective: To compare the efficacy of two protocols of controlled ovarian hyper stimulation (COHS) with recombinant Follicle Stimulating hormone (rFSH) (75 vs. 150 UI/day) plus IUI, in terms of pregnancy rate, multiple pregnancies, ovarian hyper stimulation syndrome and ovarian stimulation features.

[Differing response to GnRH antagonists in cycles of ovarian hyperstimulation plus intrauterine insemination].

Objective: To compare two flexible protocols of GnRHant in OH plus IUI vs a control group without GnRHant.

Materials And Methods: Randomized controlled trial 90 infertile patients were analyzed in 116 cycles of IUI. Cycles were randomized in 3 groups; group 1: started GnRHant when the leading follicle reached 14mm, group 2: when it reached 16mm and group 3: without GnRHant hormonal determinations were done during OH.

[Impact of office hysteroscopy in patients with a history of two or more failed cycles of IVF-ET and pre-ICSI in assisted an reproduction center].

Background: Many couples fail to achieve pregnancy instead repeated FIV-TE-ICSI cycles. Good quality embryos for successful pregnancy rates should not be count apart over endometrial receptivity.

Objective: To assess the impact of office hysteroscopy in a group of patients with two or more previous failed cycles of FIV-TE-ICSI in an assisted reproduction center.

[Twin pregnancy with complete mole and coexisting fetus after in vitro fertilization and embryo transfer complicated with placenta previa accreta. A case report].

The double twin pregnancy with complete hydatidiform mole and coexistent fetus is a rare event and perinatal treatment complex. Presents a significant case of this unusual partnership and describes their evolution. Patient of 33 years, secondary infertility factor-peritoneal tube and pregnancy achieved by in vitro fertilization and embryo transfer.

[Delivery or cesarean section and women's emotional condition].

Background: Interest to know and study women's point of view over delivery type and its late effect in emotional state has increased recently.

Objective: To determine if there is any relation between the type of delivery and emotional state in woman after the delivery or cesarean section. In addition, to know whether this resolution modifies in any way her emotional state during the puerperium.

[Perinatal results in pregnancies obtained with embryo transfer in vitro fertilization: a case-control study].

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.

[Prognostic factors of pregnancy in intrauterine insemination].

Background: The artificial insemination is the introduction of spermatozoa in the feminine genital tract without carrying out sexual contact and with the purpose of obtaining the pregnancy. The insemination intrauterine has improved its rate of success thanks to the technological advances and the best knowledge of human reproductive physiology.

Objectives: To evaluate the prognostic factors for the pregnancy success and calculate the cumulative rate per cycle in IUI (intrauterine insemination).

[Effect of intramural and subserous myomas on in vitro fertilization cycles and their perinatal results].

Objective: To evaluate the effect of intramural and subserous myomas in in vitro fertilization cycles, as well as its perinatal results.

Type Of Study: Cases and controls.

Material And Methods: All the IVF cycles between October 1999 and December 2004 were included.

[Estrogen role in the luteal phase support in in vitro fertilization with embryo transfer cycles].

Objective: To evaluate the effectiveness of estradiol administration for luteal phase support and to describe the progesterone and estradiol behavior in vitro fertilization-embryo transfer luteal phase.

Material And Methods: Patients undergoing in vitro fertilization-embryo transfer with controlled ovarian hyperstimulation and using gonadotropin releasing hormone agonist. They were divided at random into two groups: group 1 would receive progesterone alone, and group 2 would take estrogen and progesterone.

[Perinatal result of an institutional assisted reproduction program].

Background: Assisted reproductive technology manipulates masculine gametes, embryos and implantation. It also aids the known or unknown factor of sterility without having the base problem correction as a target. In vitro fertilization and embryo transfer are among these techniques.
