Background: To investigate whether endometrial volume on the day of HCG (human chorionic gonadotropin) administration is a predictor of ART (assisted reproductive outcome) outcome Materials and Methods: Two hundred and seven patients in ART cycle were included in this prospective study; In order to evaluate endometrial volume and its relationship to ART outcome. Endometrial volume obtained from...

BACKGROUND Rapid innate immune defences against infection usually involve the recognition of invading pathogens by specific pattern recognition receptors recently attributed to the family of Toll-like receptors (TLRs). Reports from our laboratory and others have demonstrated the existence of TLRs 1-6 in the female reproductive tract. However, little has been done to identify TLRs 7-10 in the fe...

BACKGROUND The rise in FSH (FSHr) that leads to the recruitment of a cohort of follicles during the menstrual cycle occurs during the luteal-follicular transition, however, it is unclear whether it consistently occurs on one particular day, or is subjected to reproductive ageing. METHODS We determined the FSHr in 836 complete menstrual cycles from 102 women with regular menses using an algori...

Matrix metalloproteinases are a highly regulated family of enzymes, that together can degrade most components of the extracellular matrix. These proteins are active in normal and pathological processes involving tissue remodeling; however, their sites of synthesis and specific roles are poorly understood. Using in situ hybridization, we determined cellular distributions of matrix metalloprotein...

BACKGROUND The number and spatial distribution of wild boars (Sus scrofa) has increased remarkably in Sweden as well as in other European countries. To understand the population dynamics of the wild boar, knowledge of its reproductive period, oestrus cycle and reproductive success is essential. The aim of this study was therefore to describe the seasonal reproductive pattern and reproductive po...

objectives in this study the association of phenotypes and activity of butyrylcholinesterase (buche) with serum level of lipid-lipoprotein and apolipoproteins during various phases of menstrual-cycle was determined. methods the study population consisted of 22 healthy women aged 19–25 years with regular menstrual cycles, 26–30 days in length. the serum levels of lipids, apolipoproteins, and buc...

Reproduction and spawning patterns of the Yellowtail scad (Atule mate) were studied in the Persian Gulf and Oman Sea (Hormozgan coastal waters) from December 2016 to November 2017. A total of 447 fish were collected from Bandar Lengeh, Qeshm Island, Bandar Abbas, and Bandar Jask landing sites. Minimum and maximum fork lengths of this species were 10 and 33 cm, with average 20.63±1.73 cm. The to...

Metazoan life cycles can be complex in different ways. A number of diverse phenotypes and reproductive events can sequentially occur along the cycle, and at certain stages a variety of developmental and reproductive options can be available to the animal, the choice among which depends on a combination of organismal and environmental conditions. We hypothesize that a diversity of phenotypes arr...

Rioux, Pierre, and Denis Rajotte. Progesterone in milk: a simple experiment illustrating the estrous cycle and enzyme immunoassay. Adv Physiol Educ 28: 64–67, 2004; 10.1152/advan.00048.2002— Experiments designed for students in reproductive physiology are rare. Here, we describe a simple experiment concerning a physiological aspect of the reproductive system. Milk samples are obtained from cows...
