Pregnancy Rates with Recombinant versus Urinary Human Chorionic Gonadotropin in In Vitro Fertilization: An Observational Study

Pregnancy Rates with Recombinant versus Urinary Human Chorionic Gonadotropin in In Vitro Fertilization: An Observational Study

Randomized clinical trials (RCTs) demonstrated the equal efficacy of urinary human chorionic gonadotropin (uhCG) and recombinant hCG (rhCG) products in in vitro fertilisation (IVF). However, limitations inherent with RCTs necessitate the reinforcement of RCT results in real-life. We retrospectively analyzed pregnancies after treatment with rhCG and uhCG products (n = 391, and 96, resp.). We fou...

Human Menopausal Gonadotropin versus Recombinant FSH in Polycystic Ovary Syndrome Patients Undergoing In Vitro Fertilization

Hyperglycosylated human chorionic gonadotropin as an early predictor of pregnancy outcomes after in vitro fertilization.

OBJECTIVE To determine whether serum hyperglycosylated human chorionic gonadotropin (hhCG) measured as early as 9 days after egg retrieval can predict ongoing pregnancies after in vitro fertilization and fresh embryo transfer (IVF-ET). DESIGN Cohort SETTING Academic assisted reproduction center. PATIENT(S) Consecutive patients undergoing IVF-ET INTERVENTION(S): Serum hhCG and hCG levels m...

Recombinant or urinary human chorionic gonadotropin in ovulation induction?

The onset of the spontaneous LH surge in women is relatively abrupt with concentrations doubling within 2 h to between 100 and 200 IU/l being sustained for 12–14 h over a mean duration of 50 h [1]. This mid-cycle surge, in addition to follicular rupture [2], promotes several periovulatory events including disruption of the oocyte– cumulus oophorus cell contact and induction of the resumption of...
