| Scientific title | Effect of progesterone administration on the duration of pregnancy after in vitro fertilisation (IVF)/ intra-cytoplasmic sperm injection (ICSI): a prospective randomised study |
| Study objectives | Treatment with progesterone is emerging as the standard of care for prevention of preterm delivery in women at high risk for preterm birth. Randomised controlled trials (RCTs) have generally shown efficacy in reducing the rate of recurrent preterm delivery in women with singleton pregnancies who were at high risk for preterm labour and delivery. Most of the successful trials have employed 17-alpha-hydroxyprogesterone caproate, and one trial has reported positive results using progesterone vaginal suppositories. Very few trials of progestogens have been reported for women at risk for preterm delivery because of multiple gestations. |
| Ethics approval(s) | The Egyptian IVF-ET Center Ethics Committee. Date of approval: 17/06/2008 (ref: 4/2008) |
| Health condition(s) or problem(s) studied | Prevention of preterm labour after IVF/ICSI |
| Intervention | Intervention group: Natural progesterone will be administered in the form of natural Prontogest® 400 mg daily through the vaginal route (pessaries). Progesterone administration will continue until delivery. Control group: Standard care only Serum progesterone will be measured at start of trial (20 weeks gestation) and at 32 weeks gestation in all participants. |
