The administration of human serum albumin has been reported to prevent severe ovarian hyperstimulation syndrome (OHSS) while undergoing ovarian stimulation protocols for in-vitro fertilization (IVF). This prospective, randomized study investigated the effectiveness of a single dose of human serum albumin (20 g) administered i.v. immediately after oocyte retrieval. Women enrolled in the IVF programme were treated with long gonadotrophin-releasing hormone agonist, triptorelin, and an individually-adjusted human menopausal gonadotrophin protocol. The criteria for inclusion in the study were young age, non-obesity, oestradiol concentration > 9200 pmol/l on the day of human chorionic gonadotrophin administration and > 20 follicles > 14 mm diameter as observed by transvaginal sonography. The treatment group (n = 22) received albumin while the control group (n = 18) did not. Patients were followed-up using ultrasound every 3 days. There was a significantly higher number of severe OHSS cases in the control group (n = 4) than in the treatment group (n = 0) (P = 0.035). Where the data base was restricted to patients with an oestradiol concentration > 15,000 pmol/l, the difference between control and treatment groups was highly significant (P = 0.008). These findings support the use of i.v. albumin in preventing severe OHSS during IVF treatment.
The characteristics were examined of 87 consecutive semen samples obtained from participants of an intra-uterine insemination (IUI) programme. The population investigated comprised 65 normozoospermic, 13 moderately oligozoospermic and nine severely oligozoospermic individuals. The samples were produced after 4 days abstinence for the first IUI and after a further day of abstinence for the second IUI. Semen volume, sperm concentration, total sperm count and total motile sperm count for the whole population decreased significantly between the first and second samples. The characteristics of the second sample were significantly decreased only for the normozoospermic group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
