MENSTRUATION PSYCHO-SOCIO-CULTURAL CONTEXT Ancient views: power, bleed but don’t die! Ceremonies: red ochre, many cultures associated with the moon, “moon blood” goddesses of ancient religions associated with the moon, fertility calendars based on the moon blood seen as cleansing and with magic powers Patriarchal societies: dangerous evil, dirty ruins crops, food isolation MENSTRUATION PSYCHO-SOCIO-CULTURAL CONTEXT (CONT’D) Contemporary view: disease model • pain • disability • mood swings • bloating, discomfort • shameful • curtail activities • no sex • PMS MENSTRUATION PSYCHO-SOCIO-CULTURAL CONTEXT (CONT’D) to hormonal fluctuations – no scientific data Men’s hormones fluctuate in 24 hrs. many times Social contagion Attributed MENSTRUATION PSYCHO-SOCIO-CULTURAL CONTEXT (CONT’D) Amenorrhea primary secondary (medications, weight loss, pregnancy, etc.) Dysmenorrhea: pain – prostaglandins MENSTRUATION Role of Pharmaceutical Industry Very negative expectations anxiety physical symptoms Unhealthy diet, no exercise, smoking Endometriosis Diane Ruble’s research Katharina Dalton (England) murder acquittals due to PMS MENSTRUATION Feminine role: sweet soft pliable never angry PMS: allowed to rage Severe PMS: PREMENSTRUAL DYSPHORIC DISORDER (DSM) very contested, not evidence based MENSTRUATION Medicalization: 50’s Valium 90’s Prozac (Sarafem) PMS not universal studies failed to show a decrement or fluctuation in physical (sports) or intellectual performances in the LUTEAL or premenstrual phase MENSTRUATION Sex During Menstruation: cultural, religious taboos up to people involved no medical contraindication orgasm relieves cramps MENSTRUATION Sex Drive and Cycle: 3 Reported Peaks: 1. at ovulation: • • increase in testosterone causes more interest in sex increase in estrogen makes women sexier, more attractive to men 2. just before/during menses 3. just after menses MENSTRUATION Why not have sex during menses? dirty, unhygienic 2. told not to 3. might catch disease 4. uncomfortable 5. embarrassing Almost 100% no oral sex Masturbation increases 1. 70+% avoid it, give these reasons: MENSTRUATION Hormonal Interplay: Hypothalamus: • GNRH: gonadotrophin-releasing hormone Uterine Phases: • • • • menstrual (days 1-5) proliferative (days 6-13) ovulatory (day 14) secretory (rest of cycle) MENSTRUATION Hormonal Interplay (Cont’d): Ovarian Phases: • follicular (days 1-12) • ovulatory (days 12-15) • luteal (days 16-28) Pituitary: FSH LH Ovarian Follicle: Estrogens and Progesterone MENSTRUATION MENSTRUAL CYCLE: 28 days Days 1-5: • low estrogen in blood signals the pituitary to secrete lots of FSH, which stimulates the follicles in the ovary (one each cycle). An egg ripens. Endometrium grows. Estrogen increases. Days 10-14: • Ovum continues to grow and bursts free of follicle on day 14: ovulation. Endometrium at its thickest, in preparation for possible pregnancy. High levels of estrogen signal the pituitary to decrease FSH and also signal the hypothalamus to produce GNRH. GNRH signals the pituitary to produce LH. MENSTRUATION MENSTRUAL CYCLE: 28 days Days 15-28: • The follicle turns into the corpus luteum (yellow body), which makes lots of progesterone (to maintain pregnancy). High levels of progesterone signal the pituitary to stop LH production, and the corpus luteum degenerates toward day 26. This leads to a sharp decrease in estrogen and progesterone and the cycle starts anew. All these feed-back loops go through the hypothalamus, as only the hypothalamus can influence the pituitary. MENSTRUATION Ovulation: Mittelschmerz (pain of the middle of the month) Anovulatory cycles (esp. adolescents and climacteric) Basal body temperature fluctuations There is an OTC kit that analyzes saliva and pinpoints ovulation • saliva ferns at ovulation just like ovulatory mucus MENSTRUATION Ovulation (Cont’d): Changes in cervical mucus during cycle: • Regular functions of non-ovulatory mucus: lubrication bacteriostatic pH regulation (acid) It is cloudy, whitish, thick, most of cycle MENSTRUATION Ovulation (Cont’d): Ovulatory cervical mucus: • days 12-16 of cycle duration varies, some women only hours. It is transparent, very stretchy, like raw egg white Functions: • • • • To help sperm regulating pH (normal to alkaline) sugars conveyor (fern pattern) CHANGES IN BASAL BODY TEMPERATURE TEMP. MENSTRUATION New Pill Suppresses Menstruation What might the consequences be? Benefits MENSTRUATION Warning: Menstrual products can be hazardous to your health! • Presence of staphilococcus aureus, particularly when using tampons, can lead to toxic shock syndrome (TSS), can be fatal. • Absorbent fibers also absorb normal vaginal secretions, leading to drying and, occasionally, ulceration, painful intercourse. • Bleaching chemicals: dioxin – used in “sanitary” products: powerful carcinogen can affect hormones immunosuppressant endometriosis Environmental Damage Disposable sanitary products contaminate water sources, both at factory sites and when disposed. Dioxin affects fish, birds, etc. If incinerated, toxic gases released (acid rain, global warming) Alternative products are available!
