In order to evaluate whether the ratio of serum estrogen level on the day of human chorionic gonadotrophin (hCG) administration to number of oocyte retrieved has any impact on live birth rate in women undergoing in vitro fertilization (IVF), we retrospectively analyzed the clinical data from 7,112 women treated with GnRH-a long protocol in our center. Cycles were firstly divided into 6 groups a...

purpose: to assess whether bromocriptine-rebound method (brm) can improve pregnancy   outcomes compared to long protocol after intracytoplasmic sperm injection cycles (icsis).   materials and methods: a total of 114 women underwent icsi. pregnancy outcomes and   hormonal data were compared between two groups, i.e. long protocol and brm. ovulatory   women with normal serum prolactin levels were ...

OBJECTIVE The aim of the study was to investigate whether the use of low molecular weight heparin (LMWH) improve live birth rates when compared with control group in patients with unexplained recurrent miscarriages (URM). METHODS In this prospective observational study 150 women with a history of two or more previous unexplained first trimester pregnancy loss who received LMWH; either enoxapa...

OBJECTIVE To evaluate ovarian response and cumulative live birth rate of women undergoing in-vitro fertilization (IVF) treatment who had discordant baseline serum anti-Mullerian hormone (AMH) level and antral follicle count (AFC). METHODS This is a retrospective cohort study on 1,046 women undergoing the first IVF cycle in Queen Mary Hospital, Hong Kong. Subjects receiving standard IVF treatm...

PURPOSE Blastocyst transfer has been recommended to raise the implantation rate without affecting the pregnancy rate. The objective of this meta-analysis is to systematically evaluate whether the live birth rate and other pregnancy outcomes can be improved by blastocyst transfer compared with cleavage-stage embryos transfer. MATERIALS AND METHODS EMBASE and MEDLINE databases were searched for...

Births According to provisional reports, an estimated 300,000 births occurred in the United States during December 1995.
