[IMSI versus ICSI for male factor infertility: A meta-analysis].

Objective: To evaluate the efficacy and safety of intracytoplasmic morphologically selected sperm injection (IMSI) versus intracytoplasmic sperm injection (ICSI) in in vitro fertilization (IVF) for couples with male factor infertility.

Methods: Using the Cochrane system evaluation method, we searched MEDLINE, EMBASE, CENTRAL, ClinicalTrials.gov, and SinoMed and manually searched the reference lists of the included studies and relevant reviews for randomized controlled trials (RCT) comparing ICSI and IMSI published from 1992 to July 2017.

Assisted Hatching in Couples with Advanced Maternal Age: A Systematic Review and Meta-analysis.

This systematic review aimed to evaluate the efficacy and safety of assisted hatching (AH) performed in couples with advanced maternal age. We searched for randomized controlled trials (RCTs) in electronic databases, including MEDLINE, EMBASE and CENTRAL (from inception to January 2018); in addition, we hand-searched the reference lists of included studies and similar reviews. We included RCTs comparing AH versus no treatment (control).

Fallopian tube occlusion with a shape memory polymer device: evaluation in a rabbit model.

Background: The present study evaluates the feasibility of a shape memory polymer (SMP) device for fallopian tube occlusion in rabbits.

Study Design: The SMP contraceptive device is made of poly(dl-lactic acid)-based poly(urethane urea) SMP in the shape of a spiral cylinder that was 10 mm long and had a diameter of 2.6 mm.

[Regulation of epidermal growth factor, thyrotropin releasing hormone and dexamethasone on the expression of fetal lung SP mRNAs in rabbits].

Objective: To compare the effect of epidermal growth factor (EGF), thyrotropin releasing hormone (TRH) and dexamethasone (Dex) on the expression of surfactant protein (SP)-A, SP-B and SP-C mRNA in fetal rabbit lungs.

Methods: Sixty-four Japanese white pregnant rabbits, put into four different groups (16 rabbits each), were given EGF (EGF group), TRH (TRH group), Dex (Dex group) or normal saline (control group) intravenously from gestational day 22(nd) (5 rabbits in each group) or 24(th) (11 rabbits in each group) for three days before killing. The levels of SP-A, SP-B and SP-C mRNAs in the fetal rabbit lungs were detected by reverse transcription polymerase chain reaction (RT-PCR) and Southern blotting.
