Infertility Clinical Trials

Recurrent pregnancy loss after spontaneous conception

Minimum three consecutive losses from pregnancies achieved after spontaneous conception

Recurrent pregnancy loss after assisted reproductive treatment

Minimum three consecutive losses from pregnancies achieved after assisted reproductive treatment (ART), which includes in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI), and frozen embryo transfer (FER).

Recurrent implantation failure

Minimum three consecutive embryo transfers (ET) of good quality embryos with no hCG production. The patient must not have experienced any clinical pregnancies (i.e. evidence of pregnancy on an US or by histopathological examination) after IVF or spontaneous conception. Biochemical pregnancies after spontaneous conception, which terminated before evidence of a gestational sac on an ultrasonic scan (US) could be visualized and before the series of RIF occurred, are accepted.
