Recombinant human follicle-stimulating hormone (r-hFSH) is widely used in fertility treatment. Although biosimilar versions of r-hFSH (follitropin alfa) are currently on the market, given their structural complexity and manufacturing process, it is important to thoroughly evaluate them in comparison with the reference product. This evaluation should focus on how they differ (e.g., active compon...
Glycans from six highly purified hFSH preparations were released by peptide-N-glycanase digestion and analyzed by negative mode nano-ESI mass spectrometry before and after neuraminidase digestion. Pituitary glycan structures were mainly high-mannose, di-, tri-, and tetra-antennary, and their abundance largely paralleled that reported by other investigators using different approaches. For most o...
OBJECTIVE To determine the safety and efficacy of a transdermal nanostructured formulation of progesterone (10%) combined with estriol (0.1%) + estradiol (0.25%) for relieving postmenopausal symptoms. METHODS A total of 66 postmenopausal Brazilian women with climacteric symptoms of natural menopause received transdermal nanostructured formulations of progesterone and estrogens in the forearm ...
Background: Ovarian physiology illustrates the synergistic interaction between luteinizing hormone and follicle stimulating hormone in the process of folliculogenesis. While follicle stimulating hormone has been well established as a marker of ovarian reserve, the role of luteinizing hormone has remained somewhat controversial and it seems to have become the ‘forgotten gonadotropin’. The follow...
BACKGROUND It has been hypothesized that alteration of hormone systems is involved in the carcinogenesis of acrylamide. The aim of the present study was to examine the cross-sectional associations between dietary acrylamide intake and sex hormone levels in premenopausal Japanese women. METHODS Study subjects were 393 women who had regular menstrual cycles less than 40 days long. Acrylamide in...
BACKGROUND Gonadotropins are protein hormones which are central to the complex endocrine system that regulates normal growth, sexual development, and reproductive function. There is still a lively debate on which type of gonadotropin medication should be used, either human menopausal gonadotropin or recombinant follicle-stimulating hormone. The objective of the study was to perform a systematic...
