Do analogues of gonadotrophin releasing hormone influence follicular fluid steroid levels, oocyte maturity and fertilization rates?

PubMed ID: 1387881One-hundred-and twelve samples of follicular fluid from 32 patients undergoing in-vitro fertilization and embryo transfer were analysed in this study. The follicular fluids were analysed for any relationships between oestradiol, progesterone and 17?-hydroxyprogesterone levels, the progesterone/oestradiol and 17?-hydroxyprogesterone/oestradiol ratios and oocyte maturity and fertilization rates. In Group A, consisting of women who used analogues of gonadotrophin-releasing hormone during ovarian stimulation with human menopausal gonadotrophin, the progesterone/oestradiol ratio rose in parallel with the fertilization rate (P < 0.05). Group B comprised patients treated with human menopausal gonado-trophin alone. No significant relationship was found between the other parameters, oocyte maturation and fertilization rates in either group. © 1992 Oxford University Press

The experimental mouse model in building an in vitro fertilization centre [DAS VERSUCHSTIERMODELL DER MAUS BEIM AUFBAU EINES IVF-ZENTRUMS]

PubMed ID: 2058341Experimental studies on animal models are necessary for the maintanence of practice and experience on IVF and ET, before starting an IVF program. Only so the handling skill of gametes zygote and human embryo culture can be improved. We have started for this reason with IVF on mouse occytes of CB6F1 Han hybrid strains and used modificated Ham's F-10 with 0.75BSA as culture medium. Until December 1988, 3652 oocytes were collected by the superovulation of 178 oocyte donor mice. The fertilization rate was 67.94%. After the transfer of 62 hybrid embryos obtained from 4 other oocyte donor mice to 4 Balb/c recipient females, 1 recipient mouse delivered 10 living hybrid mice

Determination of lupus anticoagulant (LA) and antiphospholipid antibodies (APA) in a family with systemic lupus erythematodes (SLE)

PubMed ID: 1414067The Lupus Anticoagulant (LA) is an immunglobulin directed towards the phospholipid portion of the prothrombin activator complex. This immunglobulin because first identified in the plasma of patients with Systemic Lupus Erythematodes, was named as Lupus Anticoagulant. Although initially described in patients with SLE, it was subsequently observed in other diseases and also in patients without any manifest disease. SLE or similar diseases are present in 35% of LA (+) patients. The LA prevalence in SLE patients has been found as 34% whereas ACA prevalence was found as 44%. While searching for the presence of LA and the levels of APA in cases having unexplained recurrent fetal losses, a family (a mother and 3 daughters) was discovered, whose each member has been diagnosed as SLE at different times and with different symptoms. Data suggesting the presence of LA and high APA levels were determined in all the members of the family and also it was realised that case who had recurrent fetal losses had the highest APA levels. In addition to immunoassay methods to detect APA, examination of coagulation tests in patients with unexplained thrombosis and/or fetal losses, would be of great help
