[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.
