In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...

OBJECTIVE To determine the cost-effectiveness of infertility treatments. DESIGN Retrospective cohort study. SETTING Academic medical center infertility practice. PATIENT(S) All patients treated for infertility in a 1-year time span. INTERVENTION(S) Intrauterine inseminations, clomiphene citrate and IUI (CC-IUI), hMG and IUI (hMG-IUI), assisted reproductive techniques (ART), and neosalpi...

Venous thromboembolism (VTE) affects 0.1-0.3% people each year. The risk of VTE following gynecological surgery and invasive procedures is well established and presents one of the major challenges in gynecological practice. Moreover, commonly use assisted reproductive techniques (ART) are reported to increase the risk of VTE. Despite continued efforts to reduce its incidence, postoperative VTE ...

Background: Assisted reproductive techniques (ART) are used with increasing frequency worldwide. The present research was conducted to determine the effects of ART on hearing defects and ear abnormalities. Materials and Methods: In a descriptive, cross-sectional, non-randomized study, the status of hearing and ear abnormalities was assessed in 300 newborns conceived by ART at Royan Institute, T...

Objective Despite numerous studies indicating an imperative role for reproduction, however, the role of Vitamin D supplementation on outcomes of assisted reproductive techniques remains controversial. Therefore, the objective of this clinical trial was to evaluate the effect of consumption of Vitamin D supplementation 6 weeks prior to ICSI on fertility indexes. MaterialsAndMethods The present s...

The goals and rhetoric of The Oncofertility Consortium [1] are aimed toward preserving cancer patients’ reproductive choices and facilitating their reproductive autonomy after cancer. While the end goals of oncofertility research are oriented toward safeguarding the possibility of biological reproduction for women and girls facing cancer treatments that may affect their reproductive capacity, c...

The quality of sperm DNA is very important in maintaining the reproductive potential of men. Sperm DNA is resistant to many types of insults that occur during its journey from the testis to time it reaches the oocyte for fertilization. During natural conception, a selection process occurs that allows only sperm with intact DNA to fertilize an oocyte. When assisted reproductive techniques (ART) ...

Male factor is the sole reason or a component for infertility in 20 and 30% of cases respectively. The management of the disease may be via medical or surgical treatment. The surgical approach is classified as techniques which improves sperm production and delivery in order to achieve spontaneous pregnancy or sperm retrieval techniques prior to assisted reproductive techniques (ART). Varicocele...

Much work in contemporary bioethics defends a broadly liberal view of human reproduction. I shall take this view to comprise (but not to be exhausted by) the following four claims. First, it is permissible both to reproduce and not to reproduce, either by traditional means or by means of assisted reproductive techniques such as IVF and genetic screening. Second, it is permissible either to repr...

Objective It is thought that mothers who conceive via assisted reproductive technology (ART) may be at greater risk of postpartum depression (PPD) because of the problems and psychological stresses associated with ART treatment. The aim of the present study is to determine the occurrence of PPD among mothers conceiving via ART in comparison with mothers naturally conceiving, using Edinburgh Pos...
