Maternal infection is a cause of adverse developmental outcomes. Lipopolysaccharide (LPS)-induced embryonic resorption, intra-uterine fetal death (IUFD) and preterm labor have been well characterized. In the present study, we investigated the effects of maternal LPS exposure on intra-uterine fetal growth and skeletal development. All pregnant mice except controls received an intraperitoneal inj...

The sperm count required were investigated to obtain a conception rate of 80% by unilateral intrauterine insemination (UIUI) of fresh semen in cats. The conception rates obtained by insemination before and after ovulation were also examined. Thirty-six female cats aged 1-7 years were used in the experiments, and the number of experimental cases was 44. Seven male cats aged 2-12 years from which...

Sexually mature male Mongolian gerbils, Meriones unguiculatus, from known intra-uterine positions were each paired with a succession of nulliparous females. Those males that had matured in intra-uterine positions adjacent to two males (2M males) sired an average of 28% more young than did those males that had matured in intra-uterine positions between two females (2F males). In a second experim...

The objective was to compare in the ewe the effects of easy and difficult procedures for artificial insemination (AI) (as related to rapid or poor accessibility of the cervix, respectively) on plasma cortisol (CORT) and oxytocin (OT), and uterine motility. All AI were simulated using a catheter empty of semen to study genital and environmental stimuli only. In experiment 1, 40 ewes were sampled...

BACKGROUND Pregnancy in the rudimentary uterine horn is an extremely rare clinical condition. Treatment includes surgical removal of the rudimentary horn. METHODS A rudimentary horn pregnancy was reported that occurred after intrauterine insemination. Similar cases treated with laparoscopic surgery reported in the peer-reviewed journals were reviewed as well. RESULTS Pregnancy in the right ...

Supplementation of semen extender with caffeine and CaCl(2) for artificial insemination (AI) of fresh spermatozoa has been demonstrated to reduce recruitment of uterine polymorphonuclear leukocytes (PMNs) and the activity of phagocytosis. Here, we determined if addition of caffeine and CaCl(2) to semen extender improves the fertility of frozen-thawed boar semen. In experiment 1, gilts were cerv...

The reproductive biology of Dromiciops gliroides is described from five females collected during spring (October, December 1984) in southern continental Chile. Developmental morphology of intra-uterine embryos (October litters) was examined by microscopic analysis and compared with morphological attributes of 8 pouched young (December litters). Intra-uterine embryos demonstrate ontogenetic feat...

introduction: prevalence of infertility in general population is around 15-10 percent. intra- uterine insemination (iui) is one method for treatment of infertility. success rate of this method is affected by different factors. past studies have shown that induction of ovulation and iui has increased significantly the chance of pregnancy in the infertile couple, especially male factor infertilit...
