Relationship of within-patient semen variability to outcome of intrauterine insemination.

To define the subpopulation of infertility patients who would benefit from intrauterine insemination (IUI) with swim-up homologous sperm, the relationship of within-patient semen variability to outcome of IUI was studied. The 61 women in the study had negative workups. Men had at least one semen sample with greater than or equal to 20 x 10(6) sperm/ml.

Proximal tubal occlusion: microsurgery versus IVF--a review.

The success of IVF has established it as a viable alternative to microsurgery in the treatment of infertility associated with certain types of tubal occlusion. The authors have recently reported on the success rates of microsurgery versus IVF in cases of distal tubal occlusion. The present study summarizes the results reported in the world literature for microsurgery in cases of proximal tubal occlusion secondary to surgical sterilization, previous infection, or endometriosis, and compares them with the results reported for IVF.

Hematometra-hematocolpos: a late complication of successful separation of conjoined twins.

A late complication of separation of conjoined twins, hematometra-hematocolpos, may appear with sexual maturation. An obstructed genital outflow tract can cause significant urologic and reproductive tract morbidity.

Distal tubal occlusion: microsurgery versus in vitro fertilization--a review.

The success of in vitro fertilization (IVF) has established it as a viable alternative in the treatment of infertility associated with distal tubal occlusion (DTO). In an attempt to adequately counsel patients with DTO as to whether their primary treatment should be microsurgery or IVF, the authors have performed a comprehensive world-wide literature review. Based on what has been published to date, it would appear that patients with mild to moderate tubal disease should be offered salpingoneostomy as their first treatment modality.

The effect of preimplantation culture conditions on murine embryo implantation and fetal development.

Ham's F-10 medium (Gibco, Grand Island, NY) and medium T6 with and without 15% fetal calf serum (FCS) were compared for their ability to support development of murine blastocysts with the capacity to implant and produce normal fetuses when transferred to pseudopregnant females. All media supported equal rates of blastocyst development from 2-cell embryos. In addition, there were no differences in the rates of blastocyst implantation.
