Written informed consent was obtained from the patient for publication of this case report and any images and clinical data. Acquired causes of HH are mostly due to structural or functional abnormalities involving the hypothalamic-pituitary axis, and most of these patients have multiple pituitary hormone deficiencies. Her serum hormone measurements determined the following results; follicle stimulating hormone FSH

Once secreted, GnRH binds to specific pituitary cell membrane hypofonadotropic, which results in the production of diacylglycerol and inositol triphosphate, intracellular calcium increase by mobilization from intracellular stores and extracellular influx and the activation of protein kinase C. This condition is commonly seen in association with other pituitary hormone deficiency states caused by structural lesions of the hypothalamic-pituitary region. Sertoli cells have receptors for FSH and testosterone. Due to her work assignment and work loads, she was not able to receive daily administrations of HMG or hCG, therefore, self-administration of rFSH was only what we could offer for this patient during the COS period. Definitely, there are still numerous controversial issues in the practice of medicine, requiring individual good sense for taking decisions regarding whom, when, and how to treat.

Interestingly, rare variants in the genes associated with congenital IHH were recently found in women with hypothalamic amenorrhea, suggesting that these mutations may contribute to the variable susceptibility of women to functional changes in GnRH secretion Only solution for hypogonadotropic hypogonadism is hormonal replacement therapy which includes all needed female hormones which can insure proper development.

GnRH hypogonadotropic hypogonadism pregnancy stages produced by specialized hypothalamic neurons in a pulsatile manner that stimulates the release of gonadotropins luteinizing hormone and follicle-stimulating hormone from the pituitary, which activate gonadal maturation and fertility. Shiraishi, K. It is important to consider that the first endocrinological change to occur during puberty is an increase in LH, which initially occurs more in amplitude than in frequency and only at night; subsequently, both LH and FSH levels increase at night and during the day until adult levels are reached.

FSH, in contrast, binds to FSH receptors on Sertoli cells and initiates signal transduction events that ultimately lead to the production of inhibin B, which is a marker of Sertoli cell activity. This type of phenotypic heterogeneity may be ascribed to environmental or epigenetic effects.

Serum E 2 concentrations may not be the most important index for oocyte maturation during COS, and suggested that oocyte maturation was in progress even under low serum E 2 and high P 4 conditions. Renal ultrasound examination is usually recommended to patients with syndromic IHH, such as Kallmann syndrome, independent of the genetic basis, although it is well known that unilateral kidney agenesis may be more prevalent in patients with KAL1 defects. Ovulation induction in patients with hypogonadotropic hypogonadism HH is a challenge to the treating physician.

As soon hormonal replacement starts, sooner and better the results could be.
