Preliminary study on somatic cell nuclear transfer in rabbits in Thailand.

The objective of the study was to develop the somatic nuclear transfer technique by using rabbits as the model. The oocyte recipients aged 16 h post coitus were collected surgically from 20 superovulated rabbit doe with 28 and 40 mg Follicle Stimulating Hormone (FSH) after mating with a vasectomized male. The metaphase II plate and 1st polar body of oocyte was later aspirated by enucleated micropipette under an inverted microscope.

The effect of growth hormone on the development of in vitro matured unstimulated human oocytes.

Objective: To investigate the effect of growth hormone on the development of in vitro matured unstimulated human oocytes.

Design: Randomized controlled study.

Setting: Division of Reproductive Medicine, Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn university.

Predictive value of human chorionic gonadotropin in the outcome of early pregnancy achieved by assisted reproductive technology.

This study was undertaken to evaluate the predictive value of the serum human chorionic gonadotropin (hCG) in pregnancies achieved by assisted reproductive techonology (ART). Two hundred and eighty-six pregnancies were studied retrospectively from September 1989 to June 1998. The serum hCG samples at 2-6 weeks after embryo transfer (ET) were analysed by fluoroimmunoassay.

Day 3 serum inhibin B level of poor and good ovarian responders in the IVF-program.

The aim of this study was to compare day-3 serum inhibin B levels of poor and good ovarian responders in the IVF-program. The study group consisted of 20 poor ovarian responders. The control group composed of 40 good ovarian responders who had similar demographic characteristics.
