Formaldehyde (HCHO) exposure in industry causes health impairment, especially immune profile. Male albino rats when exposed to HCHO at 5, 10, 15 mg/kg day for 30 days showed decrease in thyroid weight in 10, 15 mg/kg/day HCHO fed group with commensurate follicular regression (epithelial cells), decreased triiodothyronine (T3), thyroxin (T4) deficiency and enhanced thyroid stimulating hormone (T...
Routinely, a bolus of 5.000-10.000 IU human chorionic gonadotropin (hCG) is used for the final follicular maturation and ovulation as a standard method. HCG has the same effect of luteinizing hormone (LH) with long half-life. It has the long lutheotrophic effect which increases the risk of ovarian hyper stimulation syndrome (OHSS). Recently, gonadotropin-releasing hormone agonist (GnRH-a) trigg...
background: in vitro maturation (ivm) of oocytes reduces the costs and averts the side-effects of gonadotropin stimulation for in vitro fertilization (ivf). reliable ivm is an intellectual, scientific and clinical challenge with a number of potential applications. objective: the effect of hcg was evaluated on the timing and regulation of in vitro ovulation for the syrian mice oocytes in the pre...
background: follicle stimulating hormone (fsh) plays an essential role in reproductive physiology and follicular development. objective: a new variant of the equine fsh (efsh) gene was cloned, sequenced, and expressed in pichia pastoris (p. pastoris) gs115 yeast expression system. materials and methods: the full-length cdnas of the efshα and efshβ chains were amplified by reverse transcription ...
BACKGROUND The increase in serum estradiol (E2) concentrations during the follicular phase becomes the index of oocyte maturation in vivo. When ovarian stimulation is performed to hypogonadotropic hypogonadism (HH) patients with only follicle stimulating hormone (FSH), proper increase in serum E2 concentrations is not observed. Even if oocytes are obtained, which usually have low fertilization...
To compare the efficiency of North Carolina State University medium 23 (NCSU23) and Alpha Minimum Essential Medium (?-MEM) as a base medium, to evaluate effects Anti-Müllerian Hormone (AMH) alone or in combination with Follicle Stimulating (FSH) on vitro development steroid production isolated porcine preantral follicles. Porcine secondary follicles were cultured NCSU23 ?-MEM media for 4 days. ...
Phytonutrients get attention now days due to their wide application and tendency improve the productive reproductive performance in humans. Hydrolysable tannin (HT) is one of these bionutrients. The present study was aimed investigate therapeutic effect HT on induced polycystic ovarian syndrome (PCOS) rats. Forty-five adult female rats with 4 5 regular estrous cycle were selected. PCOS by a sin...
The objective of the present study was prospectively and randomly to evaluate the role of L-arginine in improving uterine and follicular Doppler flow and in improving ovarian response to gonadotrophin in poor responder women. A total of 34 patients undergoing assisted reproduction was divided in two groups according to different ovarian stimulation protocols: (i) flare-up gonadotrophin-releasin...
