This paper reports the effect of low-dose human chorionic gonadotropin (hCG) on the levels
of serum hCG, progesterone, and estradiol, luteal-phase length, and conception in 20 …

Objective: Non-recombinant urinary hCG (u-hCG) has proven efficacy for controlled ovarian
stimulation (COS) for purposes of IVF. A recombinant subcutaneous hCG (Ovidrel®) product …

Objective To determine if early serum hCG levels are predictive of implantation outcome in
patients undergoing IVF-ET. Design Retrospective study of IVF cycles using receiver …

This age-matched retrospective analysis compared the clinical outcomes of recombinant
human chorionic gonadotrophin (rHCG) and urinary HCG (uHCG) in patients undergoing …

Objective It is difficult to predict whether an IVF cycle resulting in implantation will eventually
lead to a term pregnancy. Physicians commonly obtain a β-hCG level 14 days after embryo …

OBJECTIVE: To determine whether the serum concentration of hCG on the day after hCG
administration (abbreviated throughout this article as [hCG]) is related to the incidence of …

Objective The aim of the study was to evaluate the predictive value of the human chorionic
gonadotropin (hCG) concentration on the 14th and 16th post-ovulation day after embryo …

Background In natural cycles, women conceive when intercourse takes place during a six-
day period ending on the day of ovulation. The current practice in intrauterine insemination …

Background: Few studies have assessed the impact of serum human chorionic
gonadotropin (hCG) levels before oocyte retrieval and luteinizing hormone receptor (LHR) …

Purpose To evaluate the relationship between serum β-human chorionic gonadotropin
(HCG) levels and early pregnancy outcomes in women who became pregnant using …
