Both cost and effectiveness should be considered conjointly to aid judgments about drug choice. Therefore, based on the results of a recent published meta-analysis, a Markov model was developed to conduct a cost-effectiveness analysis for estimation of the cost of an ongoing pregnancy in IVF/intracytoplasmic sperm injection (ICSI) cycles. In ...

This study aimed to determine whether the presence of endometrial polyps discovered during ovarian stimulation affects the outcomes of intracytoplasmic sperm injection (ICSI) cycles. This retrospective descriptive study was conducted in a private assisted reproductive technology unit. Medical records of ICSI cycles performed between January 2003 and December 2004 were ...

Identification of the ovary from which ovulation takes place in two consecutive menstrual cycles results in one of four ovulation patterns, contralateral and ipsilateral ovulations on the right or on the left ovary. Our data suggest that IVF and IUI treatment in cycles in which development of the dominant follicle ...

Hypogonadotropic hypogonadism is one of the causes of infertility. In women with hypogonadotropic hypogonadism both follicle-stimulating hormone and luteinizing hormone are required to induce optimal follicular growth and steroidogenesis. We described a case of singleton pregnancy in a 38-year-old patient, presenting with primary hypogonadotropic amenorrhea and empty sella syndrome, treated ...

Letrozole induction of ovulation in clomiphene citrate-resistant women with polycystic ovary syndrome is associated with an ovulation rate of 54.6% and pregnancy rate of 25%. There was no significant difference between letrozole responders and nonresponders in age, period of infertility, body mass index, waist circumference, LH, FSH, or LH/FSH ratio.

To compare the results of intrauterine insemination (IUI) when GnRH antagonist was added-to avoid IUI on weekend-with those obtained with the standard IUI protocol. In an IUI program under ovarian stimulation with gonadotropins when one or more follicles of 15-16 mm were seen, if it was not possible for logistic ...

Human and animal physiology are subject to seasonal, lunar, and circadian rhythms. Although the seasonal and circadian rhythms have been fairly well described, little is known about the effects of the lunar cycle on the behavior and physiology of humans and animals. The lunar cycle has an impact on human ...

For almost half a century, the first-line treatment for ovulation induction in cases of anovulation, unexplained infertility, or mild male factor has been clomifene (clomiphene citrate). Clomifene is an effective and safely used oral agent, but is known to have relatively common antiestrogenic endometrial and cervical mucous adverse effects that ...

Most previous studies that calculated cumulative delivery rates following in vitro fertilization (IVF) treatments were limited in the number of cycles and the implementation of intracytoplasmic sperm injection (ICSI). Therefore, we assessed the yield of high-order consecutive IVF treatments (up to 14 consecutive cycles) with and without ICSI. Data from ...

The study evaluated the impact of elevated oestradiol concentrations on pregnancy loss during the first trimester in singleton gestations conceived via ovarian stimulation and intracytoplasmic sperm injection (ICSI). Following determination of oestradiol concentrations during 6478 ICSI cycles, patients were assorted by oestradiol percentile. Hyper-responders were defined as patients having peak ...
Small Chanley M - - 2006
BACKGROUND: Epidemiologists often use menstrual cycle patterns as indicators of endocrine function in environmental and occupational studies, yet few studies have considered whether menstrual cycle characteristics are associated with fertility or pregnancy outcome. METHODS: We prospectively studied 470 women to determine whether cycle length or bleed length were associated with ...

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 ...

The objective of the study was to determine if nuclear magnetic resonance (NMR) spectral features of ovarian follicular fluid were correlated with the physiological status of follicles so that we could assess the feasibility of using NMR spectroscopy during assisted reproduction therapy. Thirty-five sexually mature, nullparious heifers were monitored by ...

Intra-uterine insemination (IUI) is a widely used fertility treatment for couples with unexplained subfertility. Although IUI is less invasive and less expensive than in vitro fertilisation (IVF), the safety of IUI in combination with ovarian hyperstimulation (OH) is debated. The main concern about IUI treatment with OH is the increase ...

Until recently, the main source of exogenous follicle stimulating hormone (FSH) for therapeutic use in infertility had been the urine of postmenopausal women. New developments have resulted in the production of FSH in vitro by recombinant DNA technology. The extremely high purity and batch-to-batch consistency of recombinant FSH (rFSH) make ...
Casper Robert F - - 2006
CONTEXT: For the last 40 yr, the first line of treatment for anovulation in infertile women has been clomiphene citrate (CC). CC is a safe, effective oral agent but is known to have relatively common antiestrogenic endometrial and cervical mucous side effects that could prevent pregnancy in the face of ...

BACKGROUND: Controlled ovarian stimulation (COS) with intrauterine insemination (IUI) is a common treatment in couples with unexplained non-conception. Induction of multifollicular growth is considered to improve pregnancy outcome, but it contains an increased risk of multiple pregnancies and ovarian hyperstimulation syndrome. In this study the impact of the number of ...

The morphology and physiology of the vulva and vagina change over a lifetime. The most salient changes are linked to puberty, the menstrual cycle, pregnancy, and menopause. The cutaneous epithelia of the mons pubis, labia, and clitoris originate from the embryonic ectoderm and exhibit a keratinized, stratified structure similar to ...

This prospective study shows that the early pregnancy inflammatory response following frozen embryo replacement (FER) cycles may be absent or suppressed, in contrast to that following IVF. To our knowledge, this is the first study to evaluate the maternal inflammatory response following FER cycles, but larger studies are still required ...

EEG recording was performed in healthy women during various phases of menstrual cycle. Comparative study showed that the power spectrum of EEG a-waves in central and medio-temporal areas significantly decreases during ovulation. In the menstrual phase coherent characteristics of EEG alpha-waves increased in symmetrical occipital and intrahemispheric parieto-occipital areas.

BACKGROUND: In daily practice, assisted reproductive technology (ART) cycles are often cancelled under the assumption that a prolonged stimulation period lowers the likelihood of an appropriate ovarian response. The aim of the present study was to determine whether a prolonged cycle has an adverse effect on achievement of pregnancy. METHODS: ...

Conventional treatment of normogonadotropic anovulatory infertility is ovulation induction using the antiestrogen clomiphene citrate, followed by follicle-stimulating hormone. Multiple follicle development, associated with ovarian hyperstimulation, and multiple pregnancy remain the major complications. Cumulative singleton and multiple pregnancy rate data after different induction treatments are needed. Newer ovulation induction interventions, such ...

BACKGROUND: Myotonic dystrophy (MD) is characterized by myotonia, multisystemic lesions and hypogonadism. In women, the relationship between MD and infertility remains controversial. This study investigated the ovarian status and response to controlled ovarian stimulation (COS) in MD women entering our preimplantation genetic diagnosis programme. METHODS: We elected to compare MD ...

The current method of calculating cumulative pregnancy rate can lead to an overestimation of treatment efficacy, especially over many cycles of assisted reproduction treatment. The choice of scale of passage of time should be dependent upon the types of treatment to be evaluated. The number of treatment cycles to which ...
