Semen volume, and the sperm count, motility and morphology were comparable to those(More)
The optimal timing for renal replacement therapy initiation in septic acute kidney injury (AKI) remains controversial. This study investigates the impact of early versus late initiation of continuous renal replacement therapy (CRRT) on organ dysfunction among patients with septic shock and AKI. Patients were dichotomized into "early" (simplified RIFLE Risk)(More)
A prospective randomized study was conducted at the Family Planning Association of Hong Kong to compare the efficacy of the Yuzpe regimen and levonorgestrel (0.75 mg for two doses 12 h apart) in post-coital contraception. A total of 424 subjects were recruited into the Yuzpe group and 410 subjects into the levonorgestrel group; 77 subjects in the Yuzpe(More)
The results of the cervical mucus score (CMS), basal body temperature (BBT) and a rapid urine luteinizing hormone (LH) assay by haemagglutination immunoassay were compared with plasma LH radioimmunoassay in 28 ovulatory cycles. There was good correlation of the CMS peak with the plasma LH peak while the urine LH peak usually occurred one day later. The(More)
Eighty-four Chinese patients attending the Family Planning Association of Hong Kong for contraception with oral contraceptive pills were randomized into 2 groups. The first group received pills containing 0.15 mg levonorgestrel and 0.03 mg ethinyl oestradiol. The second group received pills containing 0.15 mg desogestrel and 0.03 mg ethinyl oestradiol.(More)
The records of 227 couples who received artificial insemination by frozen donor semen in 984 treatment cycles were analysed to find out the factors affecting the pregnancy rates. The cumulative pregnancy rate at 6 months was 46.8% and the pregnancy rate per cycle was 10%. The pregnancy rates were adversely affected by (1) increase in the recipient age above(More)
