Differential effects of 2 transfer models for normal thawed embryos of 1 donor doe were studied on the offspring rate and their embryo survival at birth from 3 selected rabbit strains (SY and SB: synthetic strains, NZ: New Zealand White). Morulae were obtained 64-66 h post-coitum from 93 adult does treated with 25 IU of hCG (SY:36, NZ:27, SB:30). Morphologically normal morulae were frozen in th...

background: intrauterine insemination (iui) is the first therapeutic step in assisted reproductive techniques and many factors, including male and female infertility and technique-dependent factors, have been reported to influence pregnancy rates after iui. methods: we carried out this retrospective study on 1201 couples undergoing 3012 intrauterine insemination cycles during 2002 to 2009. preg...

background: repeated implantation failure (rif) is defined as pregnancy failure after two to six times with at least ten high grade embryo transfer to uterus. a variety of causes have been anticipated for rif, including anatomical, autoimmune, genetics, endocrine and thrombotic anomalies. factors responsible for rif have important implication regarding treatment however in many couples a perfec...

background: human fertility has been declined all over the world. advanced women’s age is one of the most important factors in determining the success of reproduction and ageing has negative impact on art outcome and advanced female age decreases the chance of live birth rates achieved using art, especially after 40 years of age. objective: to evaluate art outcomes regarding to pregnancy, abort...

To find some prognostic factors for the outcome of frozen-thawed cycles, we have retrospectively analysed all frozen pre-embryos that were thawed during 1993 and 1994 at two in-vitro fertilization (IVF) units in Sweden. Supernumerary pre-embryos were frozen from 551 oocyte retrievals and these resulted in 660 frozen-thawed cycles which lead to 623 thawed embryo transfers. The outcome of these t...

Fertility rates, pregnancy, and maternal outcomes are not well described among women with a functioning kidney transplant. Using data from the Australian and New Zealand Dialysis and Transplant Registry, we analyzed 40 yr of pregnancy-related outcomes for transplant recipients. This analysis included 444 live births reported from 577 pregnancies; the absolute but not relative fertility rate fel...

Fetal anemia, mainly due to red cell alloimmunization, is still a significant cause of fetal and neonatal mortality and morbidity. The focus of current clinical research has shifted from an invasive approach to non-invasive management and treatment of affected pregnancies, and the progress in this field is associated with a major improvement in perinatal outcome. During the last 50 years, intra...

This report examines a myriad of research on teenage pregnancy across the United States and specifically the state of Texas to elucidate the correlates involved with teenage pregnancy rates. This research includes studies compiled mostly from the 2010 census in Texas counties and employs a multiple regression analysis of the variables to determine the statistical significance of each one in rel...

Each year in the United States, 800,000-900,000 adolescents aged < or = 19 years become pregnant. Adolescent pregnancy and childbearing have been associated with adverse health and social consequences for young women and their children. This report presents estimated national numbers of pregnancies and national and state-specific pregnancy rates for adolescents aged < or = 19 years from 1995 to...
