Background: FIVCAT.NET is the registry of human assisted reproductive techniques (ART) in Catalunya to which all authorised centres are obliged to declare their activities. The Background of the present study is to describe the data on effectiveness of the ART in Catalunya over the period 2001-2005 and to compare our findings with other similar registries. Materials and Methods: The data were o...

Goat breeds from subtropical latitudes show different annual reproductive cycles. Some of them display large seasonal variations in their annual breeding season, while others display a moderate seasonality or sexual activity all year round. This reproductive seasonality causes seasonality of milk, cheese and meat productions and, as a consequence, induces wide variation in producer incomes. To ...

This work was designed to determine whether melatonin treatment at the spring equinox can induce reproductive activity in goats without separation from males (separation being the normal practice in Spanish farming systems) and whether this treatment modifies the onset of the natural breeding season. Twenty-nine entire does were distributed into two groups (Group M, n=14; Group C, n=15). A thir...

Objective: Carob (Ceratonia siliqua L.) is an evergreen tree with fruits that have potent antioxidant activity. The aim of this study was to investigate alleviative effects of carob fruit hydro-alcoholic extract (CFHAE) against reproductive toxicity induced by lead (Pb) in male mice. Material and Methods: Forty-two NMRI adult male mice were randomly categorized into 7 groups (N=6). Group ...

Background: Methylphenidate commonly known as Ritalin is one of the most common medications. The administration of Ritalin leads to increase of the activity of central nervous system. Because of this property, Ritalin may be used for maintaining alertness and improving of attention which may lead to increase of the risk of substance abuse in some cases. There is a little data about the effects ...

antioxidant are the agents which dispose / scavenge the reactive oxygen species, minimize the oxidative stress / lipid peroxidation and ultimately improve the fertilizing potential of the spermatozoa. currently, many antioxidants are under investigation and manganese is one of them in reducing the oxidative stress both in male and female. the antioxidative action of manganese (mn2+) on various ...

background successful pregnancy is the ultimate goal of almost all couples. however, this pleasant event is usually accompanied psychological and behavioral changes and can result in stress in women, particularly women who pregnant by assisted reproductive technology methods (arts). objectives this study aims to determine the anxiety level during pregnancy and its relation with infertility fact...

the purpose of this study was to investigate and compare whether the explant supernatants prepared from endometrial tissues during the proliferative phase, secretory phase and early pregnancy differ in immunosuppressive activity. specimens of nonpregnant endometrium from hysterectomies and normal first trimester decidua following elective aspiration termination of pregnancy were obtained. super...

Approximately 40-50 β-defensins are predominantly expressed in the male reproductive system of mammals. This selective expression raises the question as to the roles of these molecules in innate immunity and fertility in the male reproductive tract. Rat β-defensin 22 is an epididymis-specific β-defensin expressed in segments 12-14 of the epididymis. This protein contains both β-defensin and lec...
