OBJECTIVES To study the effects of green tea on body weight, and biochemical and hormonal profiles in obese Chinese women with polycystic ovary syndrome (PCOS). METHODS Thirty-four obese Chinese women with PCOS were randomized into either treatment with green tea capsules or placebo for 3 months. The anthropometric measurements, and biochemical and(More)
OBJECTIVE To report the type and frequency of chromosomal anomalies and Y-microdeletions among Hong Kong Chinese subfertile men with sperm concentrations lower than 5 million/mL. DESIGN. Retrospective study. SETTING A reproductive centre in Hong Kong. PARTICIPANTS A total of 295 Chinese subfertile men who underwent both karyotyping and Y-microdeletion(More)
BACKGROUND A combination of mifepristone and misoprostol provides an effective method of medical abortion for early pregnancy. This is the first randomized trial comparing the use of sublingual misoprostol with vaginal misoprostol in combination with mifepristone for termination of early pregnancies up to 63 days. METHODS A total of 224 women who(More)
OBJECTIVE To investigate the effect of high serum E(2) levels in gonadotropin-stimulated cycles (hCG+7) on the gene expression patterns of human endometrium compared with natural cycles on the seventh day of LH surge (LH+7) and elucidate the underlying molecular changes that may be related to endometrial receptivity. DESIGN Observational study. SETTING(More)
OBJECTIVE To evaluate the effect of the Eastern Body-Mind-Spirit (EBMS) group intervention on anxiety-reduction of Chinese women undergoing IVF. DESIGN Randomized controlled study. SETTING Tertiary assisted reproduction unit. PARTICIPANT(S) Two hundred twenty-seven women undergoing their first cycle of IVF treatment. INTERVENTION(S) The intervention(More)
CONTEXT Adrenomedullin (ADM) has been found expressed in the mouse oviduct and might play a role in reproduction. OBJECTIVE The objective of the study was to demonstrate the expression of ADM in the human oviduct, investigate its regulation by steroidal hormones and spermatozoa contact, and study its effect on ciliary beat frequency (CBF) in the human(More)
BACKGROUND Previous studies examining experiences of infertility focused mainly on the aspect of loss but neglected the possible gains realized through surviving the experience of infertility. The success rate of IVF remains relatively low, and we used the strengths perspective to examine adjustment after unsuccessful treatment. This study aims to provide(More)
OBJECTIVES To investigate any change in the ovaries, including early follicular serum follicle-stimulating hormone (FSH) level, total ovarian volume, total antral follicle count, and ovarian stromal blood flow, in patients who had undergone abdominal hysterectomy for benign conditions. METHODS Fifteen women with abdominal hysterectomy and conservation of(More)
With the advancement of assisted reproduction technologies, people are offered wider choices to choose the gender of their offspring and to construct ‘ideal-typed’ families with specific gender structure. Gender selection is welcomed by many societies with gender-specific preference, especially those patriarchal societies such as Chinese communities. It is(More)
Purpose : To compare the prevalence and type of Y-microdeletions in Hong Kong and Shanghai men with severe male-factor infertility. Methods : Seven Y-linked sequence tagged site (STS) primers and seven gene-specific primers were screened in 293 infertile males (139 from Hong Kong and 154 from Shanghai) and 161 fertile men (61 from Hong Kong and 100 from(More)
