OBJECTIVE To compare the outcome of intracytoplasmic sperm injection (ICSI)-ET cycles with fresh testicular spermatozoa obtained on the same day or the day before oocyte retrieval with frozen-thawed spermatozoa. DESIGN Retrospective cohort study. SETTING Fertility center. PATIENT(S) The first ICSI-ET cycle of 337 couples with motile testicular(More)
Antithyroid antibodies (ATA) are found in 5-15% of women at reproductive age and are not necessarily accompanied with thyroid dysfunction. ATA are associated with adverse effects such as spontaneous miscarriage, recurrent miscarriages, preterm delivery and maternal post-partum thyroiditis in women with normal thyroid hormone concentrations. The role of ATA(More)
To evaluate the efficacy of blastocyst transfer in women with at least two previously unsuccessful in vitro fertilization-embryo transfer (IVF-ET) attempts. Retrospective analysis of 238 couples (with previous implantation failures) had equal number (two) of cleavage-stage embryos (n = 143) or blastocysts (n = 95) transferred in the same IVF center. The(More)
Vitrification of laser treated human blastocysts using reduced concentrations of permeable cryoprotectants was carried out by submerging cut standard straws (CSS) into liquid nitrogen. The CSS were made by cutting a standard 0.25 ml straw at an angle of approximately 45 degrees . After laser assisted hatching, 6 day blastocysts (n=250) were loaded into(More)
INTRODUCTION To determine the relationship between AFC, basal FSH level, woman's age, the number of oocytes retrieved and the outcome of ICSI with testicular spermatozoa obtained with microscopically assisted testicular sperm extraction. MATERIAL AND METHODS In this retrospective cohort study, a total of 340 couples who underwent ICSI treatment with(More)
OBJECTIVES To compare the live birth rates and moderate/severe ovarian hyperstimulation syndrome (OHSS) rates of 2 different approaches using gonadotropin-releasing hormone (GnRH) agonist triggering in high responder women. Methods: A retrospective cohort study was performed to evaluate intracytoplasmic sperm injection (ICSI) and embryo transfer (ET)(More)
OBJECTIVE To determine live birth rate via m-TESE and ICSI in men who had a previous conventional testicular biopsy. STUDY DESIGN Retrospective study was conducted to analyze 86 m-TESE procedures for ICSI in NOA patients who had a previous conventional TESE. Only motile spermatozoa were used for ICSI and all other forms were discarded. Women under the age(More)
