Perinatal Outcomes in Mexican Women with Untreated Mild Gestational Diabetes Mellitus Diagnosed by the International Association of Diabetes and Pregnancy Study Groups Criteria.

Purpose: To compare the risk of adverse perinatal outcomes (APO) between pregnant women with mild gestational diabetes mellitus (GDM) diagnosed by the International Association of Diabetes and Pregnancy Study Groups (IADPSG) criteria, on no specific treatment, versus pregnant women without GDM.

Patients And Methods: A retrospective cohort study of pregnant women referred to the Instituto Nacional de Perinatología, in Mexico City, for prenatal care and delivery. Eligibility criteria were singleton pregnancy, age >18 years, gestational age 20-28 weeks, and no history of pre-gestational diabetes.

[Assessment of progesterone levels on the day of the hCG administration as a predictor of success of antagonist stimulation protocols for IVF].

Background: There are reports of deleterious effect when progesterone concentration is high during the follicular phase in cycles of in vitro fertilization. In our environment has not carried out a study to evaluate the pregnancy rate compared with progesterone concentration on the day of application of hCG.

Objective: To evaluate the pregnancy rate and outcome of in vitro fertilization cycle according to serum progesterone concentration on the day of application of hCG.

[Effect of sexual abstinence on pregnancy rates after an intrauterine insemination].

Background: There are many studies showing that more days of sexual abstinence increased sperm concentration, however, the direct influence between the days of abstinence and pregnancy rates has not been evaluated. The usual recommendation is 3-4 days prior to intrauterine insemination; this based on the interval that maximizes the number of motile sperm in the ejaculate. There are some reports with better success rate when abstinence is less than three days.
