OBJECTIVE: To evaluate the predictive efficiency of serum estradiol (E2) concentration in the mid-luteal phase regarding chemical, clinical, and ongoing pregnancies, in patients subjected to IVF/ICSI with fresh embryo transfer. METHODS: One hundred and forty-three patients undergoing IVF/ICSI met all the inclusion criteria for the present study. Most of the patients used antagonists, final maturation was achieved with recombinant chorionic gonadotrophin (HCG), and embryo transfer took place on days 3 to 5, but mostly on day 4...

Background: Women undergoing in vitro fertilization (IVF) cycles should successfully go through multiple points during the procedure (i.e., implantation, clinical pregnancy, no spontaneous abortion and delivery) to achieve live births. In this study, data from multiple cycles and multiple points during the IVF cycle are collected for each individual to model the effects of factors associated with success at different stages of IVF cycles in Iranian infertile women. MATERIALS AND METHODS: This historical cohort study includes 996 assisted reproductive technology (ART) cycles of 511 infertile women...

PURPOSE: The purpose of this study was to determine the heterotopic pregnancy rate using fresh versus frozen-thawed embryo transfers and factors associated with heterotopic pregnancy (HP). Management and clinical outcomes after heterotopic pregnancy were also evaluated. METHODS: In this retrospective cohort study, we included 12,484 women who had clinical pregnancies after in vitro fertilization treatment at our fertility center between 2012 and 2017. Patients received fresh day 3 embryos (F-D3 group), fresh day 5 blastocysts (F-D5 group), frozen-thawed day 3 embryos (T-D3 group), or frozen-thawed day 5 or 6 blastocysts (T-D5/6 groups) transfers...

Purpose: The aim of the present prospective study was to investigate the efficacy of hyaluronan (HA) using two different concentrations as embryo transfer media for in vitro fertilization embryo transfer cycles. Methods: A total of 169 cycles undergoing fresh embryo transfer on day 2 or 3, 561 cycles undergoing frozen-thawed embryo transfer on day 2 or 3, and 484 cycles of frozen-thawed blastocyst transfer were included in this study. Patients were randomly divided into two groups: transferred with low (l-HA) or high (h-HA) concentrations of HA in transfer media...

OBJECTIVE: To explore the effect of warming needling pretreatment for endometrial receptivity before frozen-thawed embryo transfer (FET). METHODS: Fifty-six repeatedly embryo transfer (ET) failure patients with ultrasound showing follicular phase endometrium of C type, hysteroscopy examination presenting endometritis were randomly assigned into an observation group (25 cases) and a control group (31 cases). The patients in the observation group three months before ET were treated with antibiotics in the menstrual period, warming needle (once a day) at Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Zhongji (CV 3), Zigong (EX-CA 1), Liangqiu (ST 34), Zusanli (ST 36), Shangjuxu (ST 37), Xiajuxu (ST 39) after menstruation until the ovulation stopped, and oral administration of progesterone was applied after ovulation...

PURPOSE: Is there a difference in implantation and pregnancy rates between embryos transferred electively at cleavage or blastocyst stage in infertile women ≤ 38 years with at least four zygotes on day 1 post retrieval? METHODS: A randomized clinical trial was conducted in a single tertiary care hospital with a sample size of 194 patients in each arm for a total population of 388 women.

Introduction: This pilot study was to evaluate the effectiveness of intrauterine infusion of autologous platelet-rich plasma (PRP) in infertile women undergoing frozen embryo transfer cycles with suboptimal endometrium. Material and Methods: Intrauterine instillation of autologous PRP was done in 68 women between 22 and 40 years, over 8 months, with suboptimal endometrial growth, and patients with repeated cycle cancellations, in addition to Estradiol valerate. Frozen embryo transfer was performed when the endometrium reached an optimal pattern in terms of thickness, appearance, and vascularity...

Pregnancy is an acquired hypercoagulable state. Most patients with thrombosis that develops during pregnancy present with deep vein leg thrombosis and/or pulmonary embolism, whereas the development of mesenteric vein thrombosis (MVT) in pregnant patients is rare. We report a case of MVT in a 34-year-old woman who had achieved pregnancy via in vitro fertilization-embryo transfer (IVF-ET). At 7 wk of gestation, the patient was referred to us due to abdominal pain accompanied by vomiting and hematochezia, and she was diagnosed with superior MVT...

Experiments were conducted to evaluate the effect of source, treatment and type of nuclear donor cells on embryonic and fetal development of somatic cell nuclear-transfer reconstructs in dromedary camel. In experiment 1, actively growing, serum starved or confluent skin fibroblast cells were used as nuclear donors. In experiment 2, skin fibroblasts from 4 different animals while in experiment 3, skin fibroblasts and cumulus cells from the same animal were used as nuclear donors. In all the three experiments, mature oocytes collected by transvaginal ovum pick up were used as recipient cytoplasts...

OBJECTIVE: Delaying embryo transfer (ET) enables us to select among the embryos available for transfer and is associated with positive effects on implantation and pregnancy outcomes. However, the optimal day for ET of human cleavage-stage embryos remains controversial. METHODS: A retrospective study of 3,124 in vitro fertilization/intracytoplasmic sperm injection cycles (2,440 patients) was conducted. We compared the effects of day 2 and 3 ET on rates of implantation and pregnancy outcomes between young maternal age (YMA; <38 years old, n=2,295) and old maternal age (OMA; ≥38 years old, n=829) patient groups...

BACKGROUND: Vitamin D and its active metabolite, 1,25-dihydroxy vitamin D (1,25-(OH)2D3), play a significant role in reproduction. AIM: To assess the effect of serum 25-hydroxy vitamin D level on oocyte quality and endometrial receptivity by studying oocyte donors and their recipients. MATERIALS AND METHODS: This prospective study consisted of two groups: Group A (recipient group) and Group B (donor group). All the participants of Groups A1 and B1 as well as Groups A2 and B2 were subcategorized into vitamin D-deficient (<20 ng/mL) and vitamin D replete-insufficient (20 to ≥30 ng/mL), respectively...

The present study was conducted to evaluate the possibility of using in vitro-produced parthenogenetic (PA) embryos for co-transfer with morulae that had been collected in vivo and cryopreserved. The proportion of PA blastocysts (20.5%) was higher than that of their in vitro fertilization (IVF) counterparts (16.6%). Although there were no differences in morphology or diameter between the two groups, the number of cells in early PA blastocysts after in vitro culture for 6 days was lower than for IVF blastocysts (25...
