18 it’s more complicated: Many concepts in this book have been simplified. There are three types of estrogen in the body (17-beta estradiol, estrone, and estriol), yet I use the word estrogen throughout this book. I may talk about low levels of this or that hormone or neurotransmitter, but one molecule does not completely cause a behavior. Nothing happens in a vacuum in the human body, and every shift in one chemical is liable to set off a cascade of events in others. Small events can trigger larger countermeasures as the body and brain struggle to reach a new balance, or homeostasis. The brain adapts to new conditions as receptors upregulate or downregulate in response to the low or high functioning of a specific neurotransmitter. Also, nothing is one-size-fits-all because everyone’s genes are different; individuals process drugs in idiosyncratic ways thanks to genetic variability, and many are more susceptible to psychiatric complaints because of their genetic predispositions.

26 normalizes our: increased SERT production, the presynaptic reuptake inhibitor upon which SSRIs dock.

26 sexual side effects: There are gender differences in serotonin receptor numbers and sensitivity. Women have slightly different responses to the serotonin-enhancing drug MDMA (called Ecstasy or Molly) due to these receptor differences, for example. Researchers have shown sex differences in the serotonin transporter where the SSRIs dock, called SERT. If you have more SERT, you have more recycling of serotonin back into the pitching cell, so less is available for the catching cell. More SERT is the opposite of more antidepressants, which block the SERT site. The gene implicated in depression that helps to guide the manufacture of SERT, called SLC6A4, has a "switch" that is turned on by estrogen. Other subtypes of serotonin receptors have gender differences or estrogen responsiveness as well. The number of SERT docking sites decreases as depressed women age, but not depressed men. This may have to do with waning estrogen levels seen after menopause. Aging seems to affect women more than men when it comes to their serotonergic systems.

Labbate, "Inability to Cry During SRI Treatment," Journal of Clinical Psychiatry 57 (1996): 593; Jonathan Price et al., "Emotional Side-Effects of Selective Serotonin Reuptake Inhibitors: Qualitative Study," British Journal of Psychiatry 195, no. 3 (2009): 211-17; Adam Opbroek et al., "Emotional Blunting Associated with SSRI-Induced Sexual Dysfunction.

122 So can stress: Stress causes the release of cortisol from the adrenal glands, which sit atop the kidneys. Cortisol counteracts insulin, causing higher blood sugar levels. It also stimulates sugar production in the liver, called gluconeogenesis, and stops the production of a transporter (called GLUT4) that sugar needs to get into the cell. All this excess glucose that isn’t burned as energy or stored for later use in the liver gets stored as belly fat.

124 Lower estrogen levels: Zenab Amin et al., "Effect of Estrogen-Serotonin Interactions on Mood and Cognition," Behavioral and Cognitive Neuroscience Reviews 4, no. 1 (2005): 43-58.

124 overall serotonin activity: Estrogen increases the expression of the gene for the enzyme that makes serotonin, and it also directly increases serotonin activity. If you want a sense of how estrogen and progesterone work as opposites, consider this: while estrogen creates high levels of serotonin by blocking its breakdown by the enzyme MAO, high progesterone levels increase MAO activity, thus lowering serotonin levels. High progesterone also inhibits testosterone’s mood-­elevating effects, which is why in the second half of your cycle, when progesterone dominates, you can feel depressed, sedated, and lackadaisical.

160 memory formation: If you stress lab rats, they release a proinflammatory cytokine called IL1-beta. If you take them away from their group housing, shock them in a separate space, and return them to their group, they’re understandably stressed when you take them back to the shocking room; they remember where they got the pain. But if you take them away from their pals, shock them, but then put them in solitary confinement, they don’t remember the shocking place. Being alone not only activates IL1-beta but also tanks the BDNF necessary to grow neuronal connections and learn something. Stress activates inflammation, which turns off the neurotrophic signals. If you block the IL1-beta, you block those changes, and you don’t see the hippocampal shrinkage and stupidity.

Chapter Eight: Food: A Drug We Can’t Resist

165 Being loved, cared for, and fed: Doidge, The Brain That Changes Itself.

166 food issues: When obese women are shown pictures of high-calorie foods, their brains show greater activity in regions associated with anticipating reward than do the brains of women with more normal weight.

166-167 in a study pitting Oreos against cocaine: Joseph Schroeder, "Oreos Trigger More Robust Dopamine Response and Place-Preference Than Cocaine in Rats," presented at Society for Neuroscience conference in San Diego, California, 2013.

167 junk foods: Rats fed junk-food diets need increasing amounts to trigger the release of dopamine and get the same brain boost. They become obese and lose control of their ability to stop eating, much like alcoholics who can’t stop at one drink. Even when electric shocks are applied to their feet, which would stop control groups from eating rat chow, if the food is cheesecake, frosting, or bacon, the rats keep on eating. When the junk food is removed and replaced with healthy food, the rats stage a hunger strike, basically starving themselves for two weeks because they’re so upset.

167 Sugar creates a "bliss point": Moss, Salt, Sugar, Fat.

167 Fat content is difficult to discern: Mirre Viskaal-van Dongen et al., "Hidden Fat Facilitates Passive Overconsumption," Journal of Nutrition 139, no. 2 (2009): 394-99; Drewnowski and Schwartz, "Invisible Fats," 203-17.

169 don’t stop eating: The way to prevent the munchies is to simply keep food out of your mouth. The endocannabinoid system is designed to make you keep eating, so just don’t start.

170 The hormone leptin: Ioannis Kyrou et al., "Stress, Visceral Obesity, and Metabolic Complications," Annals of the New York Academy of Sciences 1083, no. 1 (2006): 77-110.

170 how fat you really are: Leptin also lets your reproductive system know whether "all systems are go" and you have enough energy reserves to conceive.

170 appetite suppressant: In animals it was found to reduce all food intake, in particular "palatable" food intake, and obesity.

175 diets high in fats and low in carbs: Westman et al,. "Low-Carbohydrate Nutrition and Metabolism," 276-84; F. L. Santos et al., "Systematic Review and Meta-analysis of Clinical Trials of the Effects of Low Carbohydrate Diets on Cardiovascular Risk Factors," Obesity Reviews 13, no. 11 (2012): 1048-66.

175 cholestrol numbers: High-density lipoprotein (HDL) is the "good" type of cholesterol. The low-density lipoproteins (LDL) have the reputation of being the "bad" cholesterol, but it’s not that simple. There are smaller, dense LDLs that are bad for you, and larger, fluffy ones that are good for you, just like my mother’s matzo balls. There is an unholy trinity, called pattern B, where you see dense LDLs, low levels of desirable HDLS, and high triglycerides, a setup for narrowing the arteries with plaques, causing heart attacks or strokes. The bad matzo balls—the dense LDLs—are linked to inflammation and many medical illnesses but are not even produced by eating fat. They’re produced by excess sugars and carbs. That is a big shift from the old thinking on diet and cholesterol levels.

175 okay again: They increase LDLs, but the good, fluffy kind, and they also increase beneficial HDLs.

175 Trans fats are still bad: Esther Lopez-Garcia et al., "Consumption of Trans Fatty Acids Is Related to Plasma Biomarkers of Inflammation and Endothelial Dysfunction," Journal of Nutrition 135, no. 3 (2005): 562-66; Rajiv Chowdhur et al., "Association of Dietary, Circulating, and Supplement Fatty Acids with Coronary Risk: A Systematic Review and Meta-analysis," Annals of Internal Medicine 160, no. 6 (2014): 398-406.

176 Now, it turns out: Unique to coconut oil are its antiviral and antifungal properties. Around half the fat of coconut oil is lauric acid, a fatty acid rarely found in nature, though it is in human breast milk. Infants convert it to monolaurin, which kills some bacteria, giardia, measles, the flu, herpes, and HIV. Coconut oil is also great for your hair, cuticles, and dry skin. It can even clean your teeth. It is also a good lubricant for sex.

176 coconut oil is the hot new thing: Trent Gordon, Coconut Oil—The Numerous Advantages: Hygiene, Diet and Weight Loss (Newark, Del.: Speedy Publishing LLC, 2013).

176 acetic acid in vinegar inhibits the digestion of starches: Johnston et al., "Preliminary Evidence That Regular Vinegar Ingestion Favorably Influences Hemoglobin," e15-e17.

176 won’t be so bloated: Apple cider vinegar is made from the alcohol obtained by the fermentation of apples by yeast and bacteria. If you can get raw ACV, it’s even better, because pasteurization will?? kill off some of the good stuff, like enzymes. A tablespoon of ACV diluted in plenty of water before a meal is a common recommendation for people trying to lose weight. Dilution is crucial, because all vinegar is caustic to tooth enamel and stomach lining if not ­watered down.

Omega-3 supplementation decreases anxiety-like behaviors in rodents, nonhuman primates, and medical students. One important caveat for taking omega-3 supplements: they need to be high in EPA, at least 60 percent, and lower in docosahexaenoic acid (DHA) to have beneficial effects on psychiatric complaints.

Please note that 3 milligrams is not what is typically used for sleep. Melatonin for sleep should still be taken bewteen ten P.M. and eleven P.M., but it’s wiser to use half a milligram or 1 milligram in this case.

216 43 percent of women have complaints: Edward O. Laumann et al., "Sexual Dysfunction in the United States," JAMA 281, no. 6 (1999): 537-44.

216 sexual dysfunction: Medically, there are four categories of female sexual dysfunction: hypoactive sexual ­desire disorder (not thinking horny thoughts or wanting sex); sexual arousal disorder (not responding fully to sexual stimulation); sexual pain disorders, like dyspareunia (pain ­during intercourse) and vaginismus (muscle spasms during stimulation); and orgasmic disorder (not climaxing).

216 higher cortisol levels that inhibit: Lisa Dawn Hamilton et al., "Cortisol, Sexual Arousal, and Affect in Response to Sexual Stimuli," Journal of Sexual Medicine 5, no. 9 (2008): 2111-18.

216 restrict circulation: Diabetes, high cholesterol, cigarette smoking, crushed arteries from chronic bicycle riding, pelvic surgery, or sexual trauma.

218 this stress and anxiety jams: Berman and Berman, For Women Only.

218-219 antidepressants that enhance serotonin levels: Parks W. Walker et al., "Improvement in ­Fluoxetine-Associated Sexual Dysfunction in Patients Switched to Bupropion," Journal of Clinical Psychiatry (1993); Charles C. Coleman et al., "Sexual Dysfunction Associated with the Treatment of Depression: A Placebo-Controlled Comparison of Bupropion Sustained Release and Sertraline Treatment," Annals of Clinical Psychiatry 11, no. 4 (1999): 205-15.

219 Some SSRIs: Zoloft and Paxil have reputations as significant disrupters of sexual pleasure. Lexapro, in my experience, has less impact on sexual functioning than some of the other antidepressants, and there is a new medication, dubbed Viibryd, that seems to have even fewer sexual side effects than the others. (I know. The double i is pretty silly, but the potential side effects aren’t: nausea, insomnia, and diarrhea. Sometimes depression doesn’t seem so bad in comparison.) I have switched quite a few of my patients over from another SSRI to Lexapro or from Lexapro to Viibryd, and they do report that it’s easier for them to achieve orgasm.

220 diminish libido: Lactation (nursing) and antipsychotics can also raise prolactin levels, killing sexual ­desire.

220 Prolactin is likely part of the negative feedback mechanism: Tillmann H. C. Krüger et al., "Orgasm-Induced Prolactin Secretion: Feedback Control of Sexual Drive?" Neuroscience & Biobehavioral Reviews 26, no. 1 (2002): 31-44.

220 sex act: SSRIs are often used to treat paraphilias or sexual fetishes, eliminating behaviors that are bothersome to patients or their communities.

220 In laboratory animals, the SSRI fluoxetine: N. Maswood et al., "Modest Effects of Repeated Fluoxetine on Estrous Cyclicity and Sexual Behavior in Sprague-Dawley Female Rats," Brain Research 1245 (2008): 52-60.

220 Sex researcher Jim Pfaus explains: James G. Pfaus, "Reviews: Pathways of Sexual Desire," Journal of Sexual Medicine 6, no. 6 (2009): 1506-33.

220 sex holiday: For my patients, I often recommend that they take their antidepressants five days out of the week, Sunday through Thursday. This will allow sexual side effects to diminish by Saturday night and Sunday morning, prime sex time for those who work weekdays. Studies find no increased depressive symptoms with this schedule. Brian E. Moore and Anthony J. Rothschild, "Treatment of Antidepressant-Induced Sexual Dysfunction," Hospital Practice 34, no. 1 (1999): 89-91; Matthew J. Taylor et al., "Strategies for Managing Antidepressant-Induced Sexual Dysfunction: Systematic Review of Randomized Controlled Trials," Journal of Affective Disorders 88, no. 3 (2005): 241-54.

221 sexual side effects: It is likely the most common combination in all of psychiatry for this reason. They also happen to work very nicely together, sort of like peanut butter and jelly. Between the two of them, they create one kick-ass antidepressant, because they cover most of the neurotransmitters that are implicated in depression. In the seventies and eighties, tricyclic antidepressants were used to combat anxiety and depression. They enhanced transmission of serotonin, norepinephrine, and dopamine, and they worked well, but the side effects were unbearable for many. Combining an SSRI with Wellbutrin mimics these old tricyclics, hitting the same trifecta of neurotransmitters, but without the dry mouth, constipation, and sedation of the old days. So why not just take Wellbutrin alone? I find that it’s great for a low-energy, low-motivation depression, but it’s not that good for anxiety symptoms or if you have a "short fuse."

221 for a select few: There are a lot of women out there with the variant of the serotonin transporter gene (called SERT, where the SSRIs dock) that can make them more susceptible to the double whammy. If you are on SSRIs and have the genotype of two long genes (double-L), you’re nearly eight times more likely to have trouble with sexual dysfunction when oral contraceptives are added. Double-SERT people are more likely to be seasonal in their symptoms and tend to be better responders to SSRIs than double-S people, who tend to be more ­depressed than double-L people. So if you’re really having trouble with sexual side effects, please consider slowly tapering off your antidepressant altogether, with the help of your psychiatrist. You may be able to treat your depression in other ways, especially with phototherapy in the fall and winter if you’re a seasonally responsive double L. Or try a nonhormonal type of birth control if you can’t successfully taper.

222 In rats given an opioid receptor blocker: Tracy K. McIntosh et al., "Effects of Morphine, B-Endorphin and Naloxone on Catecholamine Levels and Sexual Behavior in the Male Rat," Pharmacology Biochemistry and Behavior 13, no. 3 (1980): 435-41.

222 blunting sensations: In experiments, THC led to delayed time in both erection and ejaculation in men. In the female rat, levels of brain endocannabinoids are lowest during estrus (their peak of sexual responsiveness and fertility) and higher during other parts of their cycle. Female rats receiving an endocannabinoid antagonist, blocking the cannabinoid receptors, had increased signs of sexual motivation, suggesting that these may be potential medications for boosting low desire in women.

223 Cannabis can help you: Barbara Lewis, The Sexual Power of Marijuana (New York: P. H. Wyden., 1970); Frank H. Gawin, "Pharmacologic Enhancement of the Erotic: Implications of an Expanded Definition of Aphrodisiacs," Journal of Sex Research 14, no. 2 (1978): 107-17.

224 Grooves get laid down: Researchers have known for decades that if you stimulate pleasure centers chemically or electrically, the learned behavior is reinforced. The dopamine and endorphin release that accompanies arousal and orgasm will further reinforce this computer-linked behavior.

224 Most concerning is that oxytocin: William Struthers, Wired for Intimacy: How Pornography Hijacks the Male Brain (Westmont, IL: Intervarsity Press, 2009).

225 no longer do it for them: Sociology researcher Philip Zimbardo, in his article "The Demise of Guys," describes a syndrome of arousal addiction that looks a bit like many of the conditions I treat in my ­office, incorporating aspects of ADHD, social anxiety disorder, depression, performance anxiety, and OCD.

227 external portion of the clitoris: We all start out as girls in the womb before the testosterone surge makes the male parts. Penises are like oversized clitorises made large by testosterone. When women are given testosterone, enlarged clitorises, called clitoromegaly, can result.

231 shape of a man’s penis: The flared glans creates suction, pulling previous sperm away from the cervix. Humans have a larger testes-to-body ratio than most primates, and the longest, thickest penises of any primate. The largest genitals are found in species where many males copulate with one female. The human testicular volume and libido are far beyond what’s needed for monogamous pairing, and having an external scrotum is associated with promiscuous mating. In a man’s semen, the later ejaculate contains enzymes that kill whatever sperm come after his. To insure against "poachers," men create more sperm when they haven’t seen their partner for a few days, even if they have ejaculated in her absence.

231 From an evolutionary standpoint: Ibid.

232 bring about climax: Sympathetic nervous system.

232 sharing your fantasies: Talk with your partner specifically about what role-playing might consist of and what the dos and don’ts are.

This activity is all mediated by oxytocin, the hormone that is released after orgasm and causes uterine contractions in childbirth, as well as prosocial, trusting behaviors.

242 rear entry: Seeing enough spots yet? There’s more: the U-spot is south of the clitoris and north of the urethra. There is plenty of erectile tissue surrounding the urethra, but it is above the urethral opening and on either side of it. The urethra itself, and the area between the urethra and the vagina, doesn’t have the same pleasurable feel when stroked, so make sure you’re in the right neighborhood when searching for this spot. The U-spot is best stimulated gently and wetly. Pressure typically is less pleasurable.
