background: peroxisome proliferative-activated receptors (ppars) are nuclear receptors that involved in cellular lipid metabolism and differentiation. the subtype ? of the ppar family (ppar?) plays important roles in physiologic functions of ovaries. objective: to determine correlation between ppar? protein level in granulosa cells and pregnancy rate in women undergoing in-vitro fertilization (...

background: reversal of tubal ligation is requested by some women for various reasons. the present study aims to determine the rate of pregnancy after tubal ligation reversal. case: in these case series, we reported fifteen women who requested tuboplasty after tubal ligation. in these cases reversal of tubal ligation was done in 15 women. pregnancy occurred in 4 women (26.6%). two term pregnanc...

Five trials were conducted with 958 virgin beef heifers to evaluate the effects of various breeding management methods on pregnancy rate at synchronized estrus and during a 45-day artificial insemination (AI) season. Synchronization was achieved with the progestin treatment regimen Syncro-Mate-B (SMB). Pregnancy rate at first service and cumulative pregnancy rate were affected (P less than .01)...

Background: Controlled ovarian stimulation (COS) has been shown to advance endometrial maturation and affect adversely implantation in assisted reproduction technology (ART) cycles. It has been reported that there is a better embryo-endometrium synchrony in frozenthawed embryo transfer (FET) cycles than fresh embryo transfer (ET) cycles. The Background of this study was to compare ongoing pregn...

BACKGROUND: Blastocyst transfer may theoretically decrease the incidence of ectopic pregnancy following IVF-ET in view of the decreased uterine contractility reported on day 5. The purpose of our study is to specifically compare the tubal pregnancy rates between day 3 and day 5 transfers. METHODS: A retrospective analysis of all clinical pregnancies conceived in our IVF program since 1998 was p...

Participants heard music snippets of varying melodic and instrumental familiarity paired with animal-name titles. They then recalled the target when given either the melody or the title as a cue, or they gave name feeling-of-knowing (FOK) ratings. In general, recall for titles was better than it was for melodies, and recall was enhanced with increasing melodic familiarity of both the cues and t...

KEY FINDINGS Monitoring sexual activity and contraceptive use among U.S. adolescents is important for understanding differences in their risk of pregnancy. In 2013, the U.S. birth rate for teenagers aged 15-19 dropped 57% from its peak in 1991 (1), paralleling a decline in the teen pregnancy rate (1-2). But these rates are still higher than those in other developed countries (3-4). Using data f...

OBJECTIVE The aim of this work was to analyse the fertility prognosis after conservative or radical surgery for tubal pregnancy. DATA SOURCES Index Medicus was searched for all attainable literature on the subject. METHODS OF STUDY SELECTION A total of 40 scientific publications through the latest 40 years were selected. For fulfilling the selection criterias the study design should appear ...
