Successful piglet production in a chemically defined system for in-vitro production of porcine embryos: dibutyryl cyclic amp and epidermal growth factor-family peptides support in-vitro maturation of oocytes in the absence of gonadotropins.

Journal of reproduction and development, 2009
To induce meiotic resumption of porcine oocytes, it is thought to be necessary to expose the cumulus-oocyte complexes (COCs) to gonadotropins during in-vitro maturation (IVM).

Targeted Next‐Generation Sequencing of the Leptin‐Melanocortin Pathway in Severe Obesity

Obesity, EarlyView.
ABSTRACT Objective Pathogenic variants in five established leptin‐melanocortin pathway genes (LEP, LEPR, MC4R, PCSK1, POMC) are associated with severe early‐onset obesity and are targets for emerging treatments. However, these variants are rare in these patients, suggesting the involvement of additional genes interacting with this pathway. Methods Next‐

The use of recombinant FSH in combination therapy in a young male with idiopathic hypogonadotropic hypogonadism

Медицинский совет, 2018
Currently, testosterone drugs are used to treat hypogonadotropic hypogonadism, which allow men to get a good height and reach a stage of sexual development corresponding to their age.

Multiple eumenorrheic cycles are necessary to observe a significant increase in estrogen exposure and ovulation in exercising women with functional hypothalamic oligo/amenorrhea undergoing a nutritional intervention: Insights from the REFUEL study

PM&R, EarlyView.
Abstract Background Due to consequences of energy‐related oligo‐/amenorrhea (Oligo/Amen) among exercising females, recovery of menses (ROM) is a priority. ROM is inconsistently defined and rarely reported with reproductive hormone (estrogen, progesterone) data, making it difficult to know when females achieve adequate recovery. Objective The purpose of
