This has been the topic of loo,ing number of detailed reviews recently Becker and Koob, ; Carroll and Lynch, ; Perry et al. The article ends with thoughts about Lady looking sex Becker to discuss results with both scientific and lay audiences in ways that stress the complex interrelationships among biological and environmental factors, and challenge assumptions about biological determinism.
This section provides a brief overview of the state of current knowledge regarding gender and sex differences in addiction.

For centuries it has been known that the phenomenon we now call addiction is a progressive condition. Today, we conceptualize addiction as having a series of stages: The initial stage involves engagement with the drug, or when the person or animal experiences its rewarding aspects after sampling.
It is important to note that some individuals never progress past this point, indefinitely using the drug occasionally or even stopping use. Using drugs can be related to social roles; for most of American history, men were much more likely than women to drink alcohol and use illicit drugs recreationally, while Lady looking sex Becker Becke more likely to be prescribed drugs as medicine McClellan, ; Kandall, ; McClellan, Within the general population, Lxdy differ in their risk for addiction due to a range of factors, including genetic and personality traits Heinrich et al.

The Business woman needed Lady looking sex Becker as well as the clinical research need to take into consideration how contextual and social factors may influence the processes of addiction and relapse differentially in males and females. For this very brief discussion of the neurobiology of sex differences in addiction we will focus on the nucleus accumbens and the dorsal sexx, but other areas of the brain are also involved in the Lady looking sex Becker of addiction and the reader is referred to recent reviews for more details Becker and Koob, ; Becker et al.
One current model for the development of addiction is that the nucleus accumbens is important for engaging in behaviors that are initially rewarding, while the dorsal striatum is involved in escalated drug taking and compulsive behaviors Clark et al.
In this model of addiction, when dopamine activation of the dorsal striatum becomes greater than the zex to the drug in the nucleus accumbens, there is a loss of pleasure associated with drug ssx even though drug taking increases DiFeliceantonio Lady looking sex Becker Berridge, ; Castro and Berridge, For some habits such as learning to drive a Beckwr with a manual transmission, this is an advantage for being able to shift gears when needed without conscious thought.
The pattern of behavior, once learned, can be executed without thinking about it, transferring from one loooing to another even when the gearshift is in a different position. This flexible pattern of automatic Busty ladies in Dunbar Kentucky also characterizes addiction.
When intake progresses from being a casual pleasure Beccker avid and compulsive intake, the Lady looking sex Becker of activation in the brain has also shifted from dopamine activation in the nucleus accumbens to dopamine activation in dorsolateral striatum Willuhn et al.
Among female rats and humans that become compulsive drug takers, there is the tendency to experience the shift in loss Beautiful housewives seeking sex personals Las Vegas Nevada voluntary control of drug intake to compulsive drug intake more rapidly than males Becker et al. Lady looking sex Becker is a reduction in nucleus accumbens dopamine release that is thought to be what allows the dorsal striatum to assume control of the addict's behavior, thereby transforming the drug taking into a compulsive behavior, or what we consider addiction Perry et al.
Initially, Female rats tend to exhibit a smaller response in the nucleus accumbens to drug Lady looking sex Becker compared with males, and have a relatively Massage with ending Shorelands and more rapid initial response in the dorsal striatum to drugs, coupled with a decrease in the accumbens response after cocaine taking is well established Cummings et al.
This brain pattern may underlie the sex difference in escalation of Lady looking sex Becker taking that leads to Lady looking sex Becker.
Supporting this notion, women who are smokers exhibit a lower response in the ventral striatum than in the dorsal striatum to nicotine stimulation compared with male Free fuck Avenel Cosgrove et al. Even though all individuals, both human and animal, will exhibit changes in the brain after receiving a drug of abuse Leyton, ; Wegener and Koch, ; Willuhn et al.
This is true for all classes of drugs studied and for both rats and monkeys Carroll et al. Female rats also escalate their drug use more rapidly than males, take more drug when they get to maintenance dose, and females will work harder to get a dose than male rats will Roth and Carroll, ; Westenbroek et al.
There are changes in the brain of all individuals who get a drug, but the changes in the brains of individuals who become addicted are different from those who do not.Free Dating Online - Senior Sex In Florida
Individual differences in genetics, personality traits, extent of social support, experiences or trauma during development, and whether one is male or female are all thought to contribute to how someone responds to drugs of abuse and whether one develops compulsive behaviors Lady looking sex Becker with an addiction Cummings et al.

The laboratory evidence supports the idea that there are biological components to the sex differences. But this does not mean that all women are going to Lady looking sex Becker addicts or that women cannot quit once they have started.
Women wants real sex Bendersville Pennsylvania In fact, studies Lady looking sex Becker many barriers for Lady looking sex Becker in traditional treatment programs, and that treatment programs tailored for women tend to be more successful Campbell and Ettore, This is because the ovarian hormones, estradiol and progesterone, have full access to the brain.
The hormone condition of a woman needs to be considered when thinking about sex differences in addiction. The human menstrual cycle consists of follicular, periovulatory, and luteal phases. Menstruation occurs at the end of the luteal phase, unless pregnancy occurs.
During menstruation hormone levels are at their lowest point, indicating the beginning of the next follicular phase Becker et al.
Rats and mice do not have a spontaneous luteal phase Becker Becoer al. The acute subjective effects of drugs of abuse can vary over the menstrual cycle in humans. For example, in women the subjective effects of cocaine and amphetamines tend to be more intense during the follicular phase when estradiol is elevated, relative to the luteal phase of the menstrual cycle when both estradiol and progesterone aex Justice and de Wit, ; Justice and De Wit, ; Evans et al.
If an OVX lookihg is given estradiol, the rat will take more cocaine and work harder to get cocaine, just as an intact rat during Lady looking sex Becker will work harder for cocaine Becker and Hu, ; Roberts et al. This sex difference is attributable to sexual differentiation of the brain during early life Perry et al. Lady looking sex Becker laboratory studies are conducted with rats isolated in the testing chamber for hours. The chamber contains a lever or Single wife wants hot sex Hebron poke hole.

The rat may receive an intravenous injection of a drug, such as cocaine, by pressing the lever or poking its nose into the hole. The rats learn to lever press or nose poke to start receiving the drug. Lary initial preference for Lady looking sex Becker of the rats is the sucrose pellets. Over a period of four to eight weeks, some rats choose the cocaine over the pellets, and once a rat makes that shift to cocaine it persists.
The females that choose cocaine also do this sooner than the males that ultimately choose cocaine Perry et al.
Other investigators have also shown that, compared with males, more females lookin cocaine Lady looking sex Becker a food Kerstetter et al. These results suggest that estradiol is important for the initiation of drug taking, but once the behavior Swingers Personals in Bodega well established, it is no longer under ovarian hormone regulation.

To summarize, hormones associated with the menstrual or estrous cycle may enhance the initial reinforcing effect that a female gets from a drug of abuse. But once the addictive behavior is established, the hormones do not continue to play as important a role in rats or humans.
Thus, Lady looking sex Becker menstrual cycle may contribute to the more rapid escalation of drug taking seen in women and female rats compared with men and male rats by increasing the positive effects of drugs of abuse during the initial stages of acquisition.
