Optimal euploid embryo transfer strategy, fresh versus frozen, after preimplantation genetic screening with next generation sequencing: a randomized controlled trial.

Objective: To compare two commonly used protocols (fresh vs. vitrified) used to transfer euploid blastocysts after IVF with preimplantation genetic screening.

Design: Randomized controlled trial.

Use of suboptimal sperm increases the risk of aneuploidy of the sex chromosomes in preimplantation blastocyst embryos.

Objective: To compare autosomal and sex chromosome aneuploidy rates of embryos derived from sperm with abnormal and normal parameters.

Design: Retrospective cohort study.

Setting: Assisted reproduction center.

Objective: To describe proximal occlusion of a hydrosalpinx by hysteroscopic placement of a microinsert before IVF-ET.

Design: Case report.

Setting: Health maintenance organization and tertiary-care assisted reproductive technology unit.

Experience with progesterone gel for luteal support in a highly successful IVF programme.

Efficacy of luteal support from single daily administration of Crinone((R)) 8% (progesterone gel) was tested in 43 women in an IVF programme with historical pregnancy rates >50%. Results were compared with those achieved in 46 women concurrently undergoing IVF and receiving 50 mg i.m.

Hysteroscopic metroplasty of the Class Va uterus with preservation of the cervical septum.

Objective: To assess the safety and efficacy of hysteroscopic resection of the uterine septum in patients with a Class Va septate uterus.

Design: Retrospective clinical study.

Setting: University outpatient surgical center.
