COVID-19 and assisted reproductive technology services: repercussions for patients and proposal for individualized clinical management.

Reproductive biology and endocrinology : RB&E ·doi:10.1186/s12958-020-00605-z

The prolonged lockdown of health services providing high-complexity fertility treatments -as currently recommended by many reproductive medicine entities- is detrimental for society as a whole, and infertility patients in particular. Global…

Determinants of the hCG Concentration in the Early Luteal Phase After Final Maturation of Follicles With Bolus Trigger of Recombinant hCG.

Frontiers in endocrinology ·doi:10.3389/fendo.2020.00137

Introduction: It has recently been shown that late follicular phase progesterone levels correlate well with those in the early luteal phase, and that progesterone levels before and 12 h after human chorionic gonadotropin (hCG) administratio…

Transcription profile of the insulin-like growth factor signaling pathway during human ovarian follicular development.

Journal of assisted reproduction and genetics ·doi:10.1007/s10815-019-01432-x

PurposeThe IGF signaling cascade exerts important regulatory functions in human ovarian folliculogenesis. The scope of this study was to evaluate the transcription profile of insulin-like growth factor (IGF) genes during human ovarian folli…

Daytime Variation in Serum Progesterone During the Mid-Luteal Phase in Women Undergoing In Vitro Fertilization Treatment.

Frontiers in endocrinology ·doi:10.3389/fendo.2018.00092

ObjectiveTo investigate whether mid-luteal serum progesterone (P4) exhibits significant fluctuations during a 12-h daytime period in women undergoing in vitro fertilization (IVF) and to explore whether the extent of these fluctuations could…

Mid-Luteal 17-OH Progesterone Levels in 614 Women Undergoing IVF-Treatment and Fresh Embryo Transfer-Daytime Variation and Impact on Live Birth Rates.

Frontiers in endocrinology ·doi:10.3389/fendo.2018.00690

Introduction: Corpus luteum (CL) produces progesterone (P4) and 17-OH progesterone (17-OH P4) during the luteal phase. Contrary to P4, 17-OH P4 is not supplied as part of the luteal phase support following IVF-treatment. Therefore, measurin…

Treatment history and outcome of 24 deliveries worldwide after autotransplantation of cryopreserved ovarian tissue, including two new Danish deliveries years after autotransplantation.

Journal of assisted reproduction and genetics ·doi:10.1007/s10815-014-0331-z

PurposeTo report another two successful pregnancies and deliveries resulting from autotransplanted cryopreserved ovarian tissue several years after the autotransplantation procedure took place. Further, to review the literature on the treat…

A common polymorphic allele of the LH beta-subunit gene is associated with higher exogenous FSH consumption during controlled ovarian stimulation for assisted reproductive technology.

Reproductive biology and endocrinology : RB&E ·doi:10.1186/1477-7827-11-51

BackgroundV-betaLH is a common genetic variant of LH caused by two polymorphic base changes in the beta subunit gene, altering the amino acid sequence (Trp8Arg and Ile15Thr). In a previous-preliminary trial performed in women undergoing IVF…

Combined down-regulation by aromatase inhibitor and GnRH-agonist in IVF patients with endometriomas-A pilot study

European journal of obstetrics, gynecology, and reproductive biology ·doi:10.1016/j.ejogrb.2009.02.001

OBJECTIVE: The key enzyme in the biosynthesis of estradiol, aromatase, has been demonstrated within endometriosis. Combined administration of aromatase inhibitor and GnRH-agonist may efficiently suppress estrogen biosynthesis through a comb…
