Active clinical trials for "Abortion, Spontaneous"

The purpose of the study is to assess the efficacy of vaginal micronized progesterone in the treatment of threatened miscarriage. All eligible pregnant women will be randomized to either receive vaginal progesterone or no treatment.Evaluation will be two weeks after intervention, then every 4 weeks up to 28 weeks gestation or termination of pregnancy.

In this study the investigators propose a randomized controlled trial to evaluate the effect of influenza vaccination on clinical pregnancy rates among women undergoing in vitro fertilization as donor egg recipients.

Gonadotropin Releasing Hormone agonist (GnRHa) triggering is used as an alternative to human chorionic gonadotropin (hCG) in GnRH antagonist protocol to eliminate the risk of ovarian hyperstimulation syndrome (OHSS). However, its main disadvantage is a significantly lower pregnancy rate, hypothesized to result from a process called "luteolysis" (demise of the corpora lutea). In order to preserve a high pregnancy rates, several luteal support regimens were investigated, including an intensive estrogen and progesterone supplementation and a daily GnRHa treatment. However, no study, so far, compared the efficacy of these two regimens. Our aim is to compare the efficacy of GnRHa versus estrogen and progesterone supplementation for luteal phase support in high responders following GnRHa triggering.

The aim of this work is to compare the effectiveness of sublingual misoprostol 400 mcg versus 800 mcg for medical treatment of the first trimester missed miscarriage.

For many years there is a lack of large randomized controlled trials that study the effect of low dose prednisone in women with RPL and thus the evidence of a probable efficacy of prednisone in RPL women remains limited and unclear. As the ESHRE recommended in 2018 (2) we aim to assess the effect of such treatment in a large trial that includes unexplained and abnormal autoimmune profile RPL patients. we also aim to assess the side effects of the treatment in RPL pregnant women.

Efficacy of low dose aspirin (LDA) versus LDA plus low-molecular-weight-heparin (LMWH) in patients with a history of recurrent miscarriages.

Evaluating the effect of intralipid on the natural killer cells

This is a randomised, double blind, multi-center, placebo-controlled study of subcutaneous NT100 in pregnant women with a history of unexplained recurrent pregnancy loss. Approximately 150 participants will be randomised to receive subcutaneous NT100 or placebo.

The purpose of this study is to determine whether sildenafil citrate is effective in improving uterine artery blood flow and oxidative stress in patients with unexplained recurrent miscarriages

US study to estimate the prevalence at birth of major birth defects (ie, those that cause significant functional or cosmetic impairment, require surgery, or are life-limiting) in children born to mothers who have received Nplate® therapy at any time during the pregnancy.
