Enclomiphene, an isomeric component of clomiphene citrate, acts antagonistically to the oestradiol receptor at the hypothalamus level, inhibiting both negative and positive feedback, and resulting in the induction of ovarian stimulation and suppression of ovulation. The minimal ovarian stimulation protocol takes full advantage of these characteristics of(More)
Although many reports support stimulated in vitro fertilization, several patients do not respond to it well. Furthermore, stimulated treatment could be associated with reduced ovarian response. We describe three successful cases involving patients of advanced age from whom dominant follicles were retrieved during the natural cycle. All patients had failed(More)
The aim of this study was to establish a simple, objective blastocyst grading system using women's age and embryo developmental speed to predict clinical pregnancy after single vitrified-warmed blastocyst transfer. A 6-year retrospective cohort study was conducted in a private infertility centre. A total of 7341 single vitrified-armed blastocyst transfer(More)
Purpose: To describe the efficacy and safety of managing ectopic pregnancies (EP) with ultrasound-guided local injections of absolute ethanol (AE). Methods: 69 cases of EP following IVF performed in our clinic were treated with a local injection of 0.3 ml AE with a 23-gauge needle under transvaginal ultrasonic guidance. The efficacy was evaluated comparing(More)
Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal-recessive disorder caused by 21-hydroxylase deficiency and manifests as hirsutism and oligomenorrhea due to excess adrenal androgen and progesterone. We report a case of a woman with NCAH who showed continuous high serum progesterone levels in the follicular phase associated with impaired(More)
Cytogenetic analysis of the retained products of conception (POC) is the most effective test for identifying miscarriage causes. However, there has been no large-scale study limited to blastocyst transfer. This study retrospectively reports the findings of 1030 cases in which POC analysis was performed after missed abortion following single blastocyst(More)
OBJECTIVE To determine whether oocyte retrieval from nondominant small follicles supplies mature oocytes and increases live births in natural cycle IVF and embryo transfer (IVF-ET). DESIGN Retrospective cohort study. SETTING Private assisted reproductive technology practice. PATIENT(S) Seven hundred seventy-one infertile women who underwent natural(More)
BACKGROUND The improved reagent for measuring estradiol (E2), the ST AIA-PACK iE2 reagent, has a higher specificity for the measurement of E2 levels than the original ST AIA-PACK E2 reagent, because of its lower cross-reactivity with estrone (E1). As we had E2 data obtained with either of the reagents, we analyzed changes in E1 and E2 levels during follicle(More)
