چکیده در این مطالعه به بررسی اثرات مفید حضور کشت اویداکت و یا ترشحات آن در مرحله ivf (in vitro fertilization) با استفاده از محیط sof (synthetic oviductal fluid) بر شاخص های رشد جنین گوسفند (میزان کلیواژ و میزان تولید و اتساع و هچ بلاستوسیست) پرداخته شده است. بدین منظور تخمک ها به صورت تصادفی در 5 گروه ivf شدند که عبارتند از: الف) ivf در محیط sof (گروه کنترل) ب) ivf در محیط sof در حضور کشت اوید...

In this paper, we introduce the concept of IVF weakly m∗-continuous mappings on between IVF minimal spaces and investigate some characterizations for such mappings. Also we study the relationships IVF weakly m∗-continuous mappings and IVF M -compactness. Key ords : IVF minimal space, IVF weakly m∗-continuous, IVF M -compact, almost IVF M -compact, nearly IVF M -compact

We introduce the concepts of IVF m-semiopen sets, IVF m-preopen sets, IVF m-semicontinuous mappings and IVF mprecontinuous mappings on interval-valued fuzzy minimal spaces. We investigate characterizations of IVF m-semicontinuous mappings and IVF m-precontinuous mappings and study properties of IVF m-semiopen sets and IVF m-preopen sets.

Since the introduction of IVF treatments, natural cycle IVF has been largely replaced by IVF with ovarian stimulation. However, natural cycle IVF has several advantages. It is associated with a close to zero multiple pregnancy rate, and a zero risk of ovarian hyperstimulation syndrome. Per cycle, natural cycle IVF is less time consuming, physically and emotionally less demanding for patients, a...

BACKGROUND Our aim was to study attitudes towards twins and single embryo transfer (SET) among IVF/ICSI-twin mothers with 3 to 4-year old children. METHODS A national survey was conducted by questionnaire (n = 1769). The study population consisted of IVF/ICSI-twin mothers (n = 266), and the two control groups of IVF/ICSI-singleton mothers (n = 764) and non-IVF/ICSI-twin mothers (n = 739), all...

BACKGROUND Although an increased risk of preeclampsia in pregnancies conceived by in vitro fertilization (IVF) has been reported, it remains unknown whether IVF is associated with preeclampsia. In the present study, we sought to investigate whether IVF is associated with preeclampsia in pregnant women using propensity score matching analysis. METHODS This study included 3,084 pregnant women w...

BACKGROUND Infertility is an increasing medical and social problem. In vitro fertilization (IVF) has become a common and accessible treatment for a wide variety of indications that have variable outcomes. Natural killer (NK) cells have been identified as relevant immunological factors involved in reproductive success or failure. OBJECTIVE The aim of this study was to compare the percentage of...

This paper reviews psychological research within the context of in vitro fertilization (IVF). The focus will be on psychological reactions before entering an IVF-procedure, during an IVF-treatment, and after both unsuccessful and successful IVF. The effects of psychosocial factors on the treatment outcome after IVF and interventions on conception rates will also be discussed. Undergoing an IVF-...

BACKGROUND In unexplained and mild male factor subfertility, both intrauterine insemination (IUI) and in-vitro fertilisation (IVF) are indicated as first line treatments. Because the success rate of IUI is low, many couples failing IUI subsequently require IVF treatment. In practice, it is therefore important to examine the comparative outcomes (live birth-producing pregnancy), costs, and cost-...

BACKGROUND In vitro fertilization (IVF) with single embryo transfer (SET) has been proposed as a means of reducing multiple pregnancies associated with infertility treatment. All existing cost-effectiveness studies of IVF-SET have compared it with IVF with multiple embryo transfer but not with intrauterine insemination with gonadotropin stimulation (sIUI). METHODS We conducted a systematic re...
