Ovarian response to follicle-stimulating hormone (FSH) stimulation depends on the FSH receptor genotype.
Because the ovarian response to FSH stimulation in assisted reproduction is variable, ranging from hyporesponse to hyperresponse, with the possible complication of ovarian hyperstimulation, it would be of great benefit to predict the response of the patients to FSH. To date, no clear-cut predictors of ovarian responsiveness to FSH have been identified. In this study, we investigated the role of...
متن کاملFSH LH : FSH ratio
Patient A was a 30-year-old white woman with a longstanding history of primary amenorrhea and infertility. By age 18 the patient had neither menstruated nor demonstrated evidence of normal breast development. At that time she was given oral contraceptives for four cycles and responded with normal vaginal bleeding. Laboratory evaluation at age 18 demonstrated a serum FSH (follicle-stimulating ho...
متن کاملGenetic and functional analyses of polymorphisms in the human FSH receptor gene.
To determine the influence of FSH receptor variants Thr307-Asn680 (TN) and Ala307-Ser680 (AS) on ovarian function, we investigated the frequency of these gene polymorphisms by using restriction fragment length polymorphism analysis and observed their effects on clinical manifestations. In a population of 522 Japanese women, the overall frequency of TN/TN (NN), TN/AS (NS), and AS/AS (SS) was 41....
متن کاملTreatment with human, recombinant FSH improves sperm DNA fragmentation in idiopathic infertile men depending on the FSH receptor polymorphism p.N680S: a pharmacogenetic study.
STUDY QUESTION Does the sperm DNA fragmentation index (DFI) improve depending on the FSH receptor (FSHR) genotype as assessed by the nonsynonymous polymorphisms rs6166 (p.N680S) after 3 months of recombinant FSH treatment in men with idiopathic infertility? SUMMARY ANSWER FSH treatment significantly improves sperm DFI only in idiopathic infertile men with the p.N680S homozygous N FSHR. WHAT...
متن کاملIsoforms and single nucleotide polymorphisms of the FSH receptor gene: implications for human reproduction.
The FSH receptor shows three single nucleotide polymorphisms (SNPs), one in the promoter and two in exon 10. In addition, the FSH receptor mRNA undergoes extensive alternative splicing. While no physiological role for the SNP in the promoter and for alternative spliced isoforms has been demonstrated so far, the SNPs in exon 10 result in four discrete allelic variants characterized by the amino ...
