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...

Vaginal ultrasonography of uterine peristalsis during the follicular phase of the menstrual cycle demonstrates an increasing frequency and intensity of subendometrial and myometrial peristaltic waves as the follicular phase progresses. During this time the numbers of contraction waves with a fundo-cervical direction decrease considerably in favour of waves of contraction with a cervico-fundal d...

Objective(s): The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. Materials and Methods: The patients were fertile women with normal menstrual cycle, proposed to get in vitro fertilization (IVF) treatment due to oviduct obstruction or male infe...

In order to clarify the endocrinological profiles of inhibins during normal menstrual cycles in Japanese monkeys, plasma concentrations of inhibin A and inhibin B were measured by enzymelinked immunosorbent assay. In addition, circulating gonadotropins and steroid hormones were measured. Blood samples were taken from four Japanese monkeys showing normal menstrual cycles. Plasma inhibin A remain...

In semantic categorization processes, individuals form a relation between perceived or imagined objects and knowledge about these objects. In the present semantic categorization study, we correlated endogenous 17-β-estradiol levels (E2) with performance as well as amplitude of theta oscillations in young women (age 23.1±3.4 years). The semantic categorization task consisted of nouns representin...

Objective: The aim of the presented study is to investigate the impact of progesterone change in the late follicular phase on the pregnancy rates of both agonist and antagonist protocols in normoresponders. Study design: A total of 201 normoresponder patients, who underwent embryo transfer were consecutively selected. 118 patients were stimulated using a long luteal GnRH agonist protocol and 83...

Sir, We would like to thank Dr Manno for the comments regarding pre-ovulatory progesterone levels in our paper on controlled ovarian stimulation with hCG supplementation (Thuesen et al., 2012). Dr Manno concluded that our study was another study denying a prognostic value to pre-triggering P4 levels. We think that our study should not be used to clarify a possible role of elevated progesterone ...

A unique feature of the reproductive physiology of Asian elephants (Elephas maximus) is the occurrence of two LH surges before ovulation, instead of one. An anovulatory LH (anLH) surge, the function of which is unknown, occurs consistently 3 weeks before the ovulatory LH (ovLH) surge that induces ovulation. Thus, the ability to induce an ovLH surge would be useful for scheduling natural mating ...
