A "kiss" before conception: triggering ovulation with kisspeptin-54 may improve IVF.

چکیده
A 30-year-old primigravid (G1P000) female with infertility secondary to her partner's oligospermia and her chronic anovulation presented 13 days after an oocyte retrieval for in vitro fertilization (IVF) with a positive home pregnancy test, abdominal distention, a 5-pound weight gain, nausea, shortness of breath, and reduced urinary frequency. Her IVF cycle included the usual cocktail for gonadotropin stimulation and was uncomplicated, except for excessively stimulated ovaries that led to a peak estradiol level of 6,000 pg/ml and the retrieval of 30 oocytes. Her past history was relevant only for anovulation due to polycystic ovarian syndrome (PCOS), though her preprocedure body mass index was normal at 21 kg/m2. Pelvic ultrasound revealed abundant ascites and enlarged ovaries, at 8 cm average diameter. Serum human chorionic gonadotropin (hCG) concentration was 200 mIU/ml; she was hemoconcentrated (hemoglobin 16 g/dl), with normal liver function and coagulation testing. An ultrasound guided, transvaginal paracentesis removed 4 liters of straw-colored fluid, resulting in significant short-term symptom relief.

KiSS-1 in the mammalian ovary: distribution of kisspeptin in human and marmoset and alterations in KiSS-1 mRNA levels in a rat model of ovulatory dysfunction.
Kisspeptins, the products of the KiSS-1 gene acting via G protein-coupled receptor 54 (GPR54), have recently emerged as pivotal signals in the hypothalamic network triggering the preovulatory surge of gonadotropins and, hence, ovulation. Additional actions of kisspeptins at other levels of the hypothalamic-pituitary-ovarian axis have been suggested but remain to date scarcely studied. We report...
متن کاملThe role of kisspeptin signalling in control of reproduction in genetically similar species.
Kisspeptin (previously known as metastin) is a protein encoded by the KISS-1 gene in humans. Kisspeptin producing neurons seem to bridge the gap between the sex steroid levels and feedback mechanisms that control the gonadotropin releasing hormone secretion. Since 2003, there are many studies on the facets of neuroendocrine networks that control puberty and fertility. These have explored the ro...
متن کاملLIM-homeodomain transcription factor Isl-1 mediates kisspeptin's effect on insulin secretion in mice.
Kisspeptin and the G protein-coupled receptor 54 (GPR54) are highly abundant in the pancreas. In addition, circulating kisspeptin directly influences insulin secretion through GPR54. However, the mechanisms by which kisspeptin affects insulin release are unclear. The LIM-homeodomain transcription factor, Isl-1, is expressed in all pancreatic islet cells and is involved in regulating both islet ...

CONTEXT In vitro fertilization (IVF) treatment is an effective therapy for infertility, but can result in the potentially life-threatening complication, ovarian hyperstimulation syndrome (OHSS). OBJECTIVE This study aimed to investigate whether kisspeptin-54 can be used to effectively and safely trigger oocyte maturation in women undergoing IVF treatment at high risk of developing OHSS. SET...

Background GnRH agonist triggering is one of the strategies for ovulation triggering and final maturation of oocytes. So , should be notice for luteal phase support in these cycles. At the first it was began for prevention of severe OHSS but it was associated with luteal phase problem and lower pregnancy rate due to luteolysis effects of GnRH agonists. So, two other alternative strategies have ...
