Utrogestan as an Effective Oral Alternative for Preventing Premature Luteinizing Hormone Surges in Women Undergoing Controlled Ovarian Hyperstimulation for In Vitro Fertilization
A major cause of cycle cancellation during controlled ovarian hyperstimulation (COH) in women undergoing in vitro fertilization (IVF) is the occurrence of premature luteinizing hormone (LH) surges. Steroidal preparations can modulate the secretion of gonadotropins (Gn); however, few studies using progesterone to inhibit the premature LH surges in COH have been published. The purpose of the stud...
متن کاملVariant-beta luteinizing hormone is not associated with poor ovarian response to controlled ovarian hyperstimulation
BACKGROUND The most common genetic variant of luteinizing hormone (LH), variant-betaLH, has a different bioactivity than the wildtype. Carrying the variant allele was associated with an increased consumption of exogenous gonadotropin to achieve optimal ovarian response for in vitro fertilization procedures (IVF). The aim of this study was to examine if variant-betaLH was also more common in pat...
متن کاملDose-finding study of daily gonadotropin-releasing hormone (GnRH) antagonist for the prevention of premature luteinizing hormone surges in IVF/ICSI patients: antide and hormone levels.
BACKGROUND The aim of this study was to define the minimal effective dose of antide (Iturelix) to prevent premature luteinizing hormone (LH) surges in in vitro fertilization (IVF) patients. METHODS In a prospective, single centre study, 144 IVF/ICSI patients were stimulated with r-hFSH from cycle day 2 and from cycle day 6 onwards, cotreated with daily 2 mg/2 ml (n=30), 1 mg/ml (n=30), 0.5 mg...
متن کاملRoles of follicle stimulating hormone and luteinizing hormone in controlled ovarian hyperstimulation.
With the advent of recombinant follicle stimulating hormone (FSH) and luteinizing hormone (LH), free from contamination with each other (Loumaye et al., 1995), it is possible to dissect the individual contributions of FSH and LH to the regulation of ovarian function and to define optimal gonadotrophin usage in controlled ovarian hyperstimulation (COH) (Hillier, 1994). Basic and clinical researc...
متن کاملP-53: The Unexpected Occurrence of SpontaneousPregnancy during Hormone ReplacementTherapy for Premature Ovarian Failure
Background: Premature ovarian failure (POF) is defined by the association of amenorrhea, hypoestrogenism and elevated (menopausal) levels of serum gonadotropins before age of 40 years-old. This condition affects approximately %1 of women under 40 years of age. Physiologic replacement of ovarian steroid hormones seems rational until the age of normal menopause. Temporary return of ovarian functi...
