The use of vaginal natural progesterone for prevention of preterm birth in IVF/ICSI pregnancies.

The aim of this study was to evaluate the effect of vaginal natural progesterone on the prevention of preterm birth in IVF/intracytoplasmic sperm injection (ICSI) pregnancies. A single-centre prospective placebo-controlled randomized study was performed. A total of 313 IVF/ICSI pregnant patients were randomized into two groups for either treatment with daily 400 mg vaginal natural progesterone or placebo, starting from mid-trimester up to 37 weeks or delivery.

A simple and relatively painless technique for hysterosalpingography, using a thin catheter and closing the cervix with the vaginal speculum: a pilot study.

Objective: To evaluate the use of a thin catheter for hysterosalpingography (HSG) for reducing the pain experienced during the procedure.

Methods: Infertile women undergoing tubal patency tests were randomised into two groups. In the study group (n=66) a thin catheter originally designed for intrauterine insemination was used to inject the dye.
