BACKGROUND: Patients undergoing in vitro fertilisation (IVF) receive various adjuvant therapies in order to enhance success rates, but the true benefit is actively debated. Growth hormone (GH) supplementation was assessed in poor-prognosis women undergoing fresh IVF transfer cycles. METHODS: Data were retrospectively analysed from 400 IVF cycles, where 161 women received GH and 239 did not. RESULTS: Clinical pregnancy, live birth rates and corresponding ORs and CIs were significantly greater with GH, despite patients being significantly older with lower ovarian reserve...

INTRODUCTION: Acupuncture is commonly used in various aspect of Western medicine in recent years including in-vitro fertilization (IVF) treatment. Although there are many clinical trials of acupuncture in IVF and the Cochrane meta-analysis did not find benefit of adjuvant acupuncture for IVF, there is no report on the pregnancy outcomes of women who had received acupuncture during their IVF treatment. OBJECTIVES: To compare the pregnancy outcomes of women randomized to receive real versus placebo acupuncture during their IVF treatment...

BACKGROUND OR OBJECTIVE: Endometriosis is common in women referred for infertility. In vitro fertilization provides good results but the choice of the best controlled ovarian hyperstimulation protocol remains a subject of debate. The objective of this retrospective study was to compare pregnancy outcomes in women with endometriosis-associated infertility after COH with a long agonist protocol or a six-week oral contraception-antagonist protocol. MATERIAL AND METHODS: Retrospective analysis of a prospective database identified 284 COH cycles - 165 with GnRH-agonist protocol (GnRH-agonist group) and 119 with GnRH-antagonist protocol (GnRH-antagonist group) - in 218 women, with endometriosis from January 2013 to October 2015...

This study aimed to evaluate the effect of oestrous synchrony between donors and recipients and the embryo quality on the pregnancy rate in beef cow recipients. The experiment was performed over two years at an embryo transfer (ET) centre in Southern Brazil. Ninety Aberdeen Angus cows were subjected to superovulation (SOV) protocols, resulting in the recovery of 1,048 transferable embryos. Eleven groups were formed with intervals of 6 hr, from -30 to +30 hr, with respect to recipient versus donor oestrous detection...

Anonymized data were obtained from the Human Fertilization and Embryology Authority to determine whether gestational surrogacy influences perinatal outcomes compared with pregnancies after autologous IVF. A total of 103,160 singleton live births, including 244 after gestational surrogacy, 87,571 after autologous fresh IVF and intractyoplasmic sperm injection (ICSI) and 15,345 after autologous frozen embryo transfers were analysed. Perinatal outcomes of pretern birth (PTB), low birth weight (LBW) and high birth weight (HBW) were compared...

PURPOSE: The aim of this study was to explore the factors that influence the outcome of intrauterine human chorionic gonadotropin (hCG) infusion at the time of embryo transfer (ET), in particular, the effect of hCG infusions on fresh and frozen embryo transfers (FETs) and whether prior recurrent implantation failure (RIF) impacts upon outcomes.

OBJECTIVE: This study aimed to explore an appropriate selection for the patients with single fair cleavage-stage embryo on day 3. METHODS: This study included 469 fresh transfers and 220 frozen-thawed transfers from January 2014 to June 2016. Furthermore, in 72 patients who have only 4-6 fair embryos (4-5 blastomeres) on day 3, the blastocysts were cultured to day 5 for transfer. RESULTS: In the fresh transfers, the clinical pregnancy rate of 4-5 blastomeres group was significantly lower than 6-7 and 8-10 blastomeres group (5...

OBJECTIVES: To perform a systematic review and meta-analysis of the known literature to assess whether the perinatal outcomes are different after oocyte donation (OD) compared to autologous oocyte (AO) in vitro fertilization (IVF) pregnancies. STUDY DESIGN: A systematic literature search was done for studies published in English from 1980 to 2016. Studies comparing perinatal outcomes of pregnancies following fresh or frozen OD and AO IVF were included. Meta-analysis was performed using the Rev Man 5...

Context: Women with polycystic ovary syndrome (PCOS) commonly have intrinsic insulin resistance and are recommended to undergo an oral glucose tolerance test (OGTT) for diabetes screening. However, the effect of preconception impaired glucose tolerance (IGT) on pregnancy is still unclear. Objective: To prospectively assess the effect of preconception IGT on pregnancy outcomes. Design, Setting, Patients, Intervention(s) and Main Outcome Measure(s): This was a secondary analysis of a multicenter randomized trial in 1508 women with PCOS comparing live birth and obstetric complications between fresh and frozen embryo transfer...

BACKGROUND: Pregnancies achieved through in-vitro fertilisation (IVF) are associated with adverse first trimester outcomes in comparison to spontaneously achieved pregnancies. In view of this, it is imperative to predict the success as well as prognosticate the pregnancy outcome of an IVF cycle not only for the clinicians but also the couples undergoing IVF. Serum beta-human chorionic gonadotropin (β-hCG) value has, thus, been used as a biomarker for pregnancy outcome after IVF and also an aid in counselling and management of the patient...

OBJECTIVE: To investigate the influence of site of embryo transfer (ET) on reproductive outcome. MATERIALS AND METHODS: A retrospective analysis of 743 ultrasound-guided ET in fresh in vitro fertilization (IVF) cycles from a single center over a period of 4 years was conducted. The distance between the fundal endometrial surface and the air bubble was measured, and accordingly, patients were divided into four groups (≤10 mm; >10 and ≤15 mm; >15 and 20 mm; >20 and <25 mm)...

Preimplantation genetic diagnosis (PGD) is a clinically feasible technology to prevent the transmission of monogenic inherited disorders in families afflicted the diseases to the future offsprings. The major technical hurdle is it does not have a general formula for all mutations, thus different gene locus needs individualized, customized design to make the diagnosis accurate enough to be applied on PGD, in which the quantity of DNA is scarce, whereas timely result is sometimes requested if fresh embryo transfer is desired...

PURPOSE: To study the association between the numbers of oocytes retrieved and the cumulative live birth rates (LBR) in women aged 35-40 years undergoing long GnRH agonist IVF/ICSI cycles. METHODS: A total of 931 women aged 35-40 years who underwent their first cycle of IVF/ICSI treatment between January 2010 and December 2013 at Nanjing Drum Tower Hospital were identified and reviewed. The main endpoint of this study was the cumulative LBR after one complete oocyte retrieval, which included fresh and all subsequent frozen-thaw embryo transfer cycles...

The oil overlay micro-drop system is widely used for cultures of mammalian gametes and embryos. We evaluated hereby the effects of two unaltered commercial oils- Sigma mineral oil (S-MO) and Nidoil paraffin oil (N-PO)-on in vitro embryo production (IVP) outcomes using a pig model. The results showed that while either oil apparently did not affect oocyte maturation and fertilization rates, S-MO negatively affected embryo cleavage rates, blastocyst formation rates, and, consequently, total blastocyst efficiency of the system...
