OBJECTIVE The purpose of this study was to quantify the contemporary procedure-related loss rate after midtrimester amniocentesis using a database generated from patients who were recruited to the First And Second Trimester Evaluation of Risk for Aneuploidy trial. METHODS A total of 35,003 unselected patients from the general population with viable singleton pregnancies were enrolled in the F...

OBJECTIVES The aim of the present study was to compare two procedures for sperm selection in ICSI cycles - conventional morphology sperm selection (ICSI-PVP) and chemical selection through Hyaluronan-treated petri dishes (PICSI), when male factor was associated. METHODS The evaluated parameters were semen quality, fertilization and cleavage rates, chemical and clinical pregnancy rates, as wel...

Objective Indications for preimplantation genetic diagnosis (PGD)/preimplantation genetic screening (PGS) cycles and clinical outcomes were evaluated at CHA Gangnam Medical Center. Methods This is retrospective cohort study. All patients (n=336) who went through in vitro fertilization (IVF)-PGD/PGS cycles (n=486) between January 2014 and December 2015 were included in Fertility Center of CHA ...

CONTEXT Unintended pregnancy is a key reproductive health indicator, but rates have never been calculated for all 50 states. METHODS State-level estimates of unintended pregnancy rates in 2006 were calculated using data from several sources. The proportion of births resulting from unintended pregnancies was obtained from the Pregnancy Risk Assessment Monitoring System and similar state survey...

Purpose: To analyze whether the thyroid status is affecting in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) outcomes. Methods: In this retrospective cohort study, we reviewed the medical records of 426 infertile women who underwent IVF/ICSI cycles. Included were hypothyroid (HypoT-LT4) patients with serum thyroidstimulating hormone (TSH) concentrations > 4.0 μIU/mL, which wer...

This retrospective analysis compared the outcomes of fertilization and pregnancy rates of 107 azoospermia patients treating with intracytoplasmic sperm injection (ICSI). Sperms were obtained by testicular biopsy surgery, with which we used in ICSI subsequently. The outcomes were compared by different kinds of causes leading to azoospermia in the 107 cases. 69 cases of obstructive azoospermia an...

s:1454:"Background: Intracytoplasmic sperm injection(ICSI) outcome is tighly depending of male and female factors. The assessment of several clinical and laboratory parameters may predict results of ICSI. Materials and Methods: We restrospectively analysed patients who had ICSI for male or female factor infertility. The clinical and laboratory factors that influenced the fertilization, pregnanc...

treatments the cows were randomly assigned to two groups. One group of cows (n= 281) was fed 0.5 mg of melengestrol acetate (MGA) per head per day for ten days while the other group of cows (n= 257) served as controls. All cows were bled for progesterone concentrations at the beginning of the MGA feeding (d -21), before the SMB treatment, and at the time of artificial insemination (AI). Twenty-...

BACKGROUND Vitamin D plays a role in reproductive capacity. Recently, several investigators have demonstrated higher IVF pregnancy rates in vitamin D replete women. The objective of this study was to validate these findings and to further elucidate the role of vitamin D in reproduction among a diverse group of women. METHODS This was a retrospective cohort study in an academic tertiary care c...
