the aim of this study was to evaluate the defense cells changes of cervical mucous during follicular and luteal phases of estrus cycle in river buffalo. reproductive organs of the adult and apparently healthy female buffaloes were collected from the slaughterhouse. by visual investigation of both the ovaries for presence of corpus luteum and growing follicles, the luteal and follicular phase of...

BACKGROUND Blood flow in the corpus luteum (CL) is associated with luteal function. The present study was undertaken to investigate whether luteal function can be improved by increasing CL blood flow in women with luteal phase defect (LFD). METHODS Blood flow impedance in the CL was measured by transvaginal color-pulsed-Doppler-ultrasonography and was expressed as a resistance index (RI). The...

background: luteal phase support is mandatory in art (assisted reproductive technologies) for optimizing outcome, so the luteal phase is supported with either progesterone, addition of estradiol to progesterone, hcg or gonadotropin releasing hormone (gnrh) agonists. supplementation of luteal phase with progesterone is prescribed for women undergoing routine ivf treatment. objective: to compare ...

This study was conducted to evaluate histochemical alterations of river buffalo’s uterine wall acid andalkaline phosphatases (ALP and ACP), lipase and carbohydrate ratio during follicular and luteal phases.Forty apparently healthy and non pregnant river buffalos were considered for removal of the uterus aftersacrifice in slaughterhouse. All dissected uteri were divided into two luteal (by obser...

background: to achieve multiple oocytes for in vitro fertilization, ovulation induction is induced by gonadotropins however, it has several effects on oocytes and embryo quality and endometrium receptivity. the aim of this study was to assess ultrastructural changes of corpus luteum after ovarian induction using human menopausal gonadotropin (hmg) and human chorionic gonadotropin (hcg) during l...

background: the aim of this study, we have compared the advantages of oral dydrogestrone with vaginal progesterone (cyclogest) for luteal support in intrauterine insemination (iui) cycles. progesterone supplementation is the first line treatment when luteal phase deficiency (lpd) can reasonably be assumed. objective: this study was conduct to compare the effect of oral dydrogestrone with vagina...

A meta-analysis was conducted to summarize the results of studies which have described the profiles of hormones during the oestrous cycle in buffalo using a fixed effect model and a random effect model. Plasma progesterone concentrations were lowest (0.30±0.06 ng/ml) during the peri-oestrous phase and increased (p = 0.067) through the early luteal phase to a maximum concentration (1.94±0.03 ng/...

introduction: suicide or para suicide is one of the known complications all around the world that unfortunately has had an increasing trend in recent decades. the aim of this study was to investigate the relationship between different phases of menstrual cycle and suicide attempts among suicidal women who referred to the poisoning ward of farschian hospital, hamedan, iran. materials and methods...

Introduction: Gonadotropin inhibitory hormone (GnIH) has been known as a key inhibitor of the secretion of gonadotropin releasing hormone (GnRH). Ewe has estrous cycles comprising of follicular and luteal phases. Follicular phase is in turn divided into proestrous and estrous phases. Blood level of LH increases in follicular and decreases in luteal phases. The aim of the present study was to...
