Premenstrual Syndrome
-
Definition
-
Original definition (R. T. Frank, 1931) of Premenstrual Tension was mood
changes occurring in the 3 to 4 days immediately preceding menstruation.
-
Included
-
depression
-
anxiety
-
irritability
-
low self-esteem
-
Later Definitions became much broader
-
Often included
-
behaviors and
-
physical and intellectual functioning
-
Four Types of Studies of PMS
-
Correlation of behaviors with cycle phase
-
49% of crimes committed by women
-
45% of calling in sick
-
46% of psychiatric admissions
-
52% of accident/emergency admissions
-
54% of mothers of children brought to a clinic for a minor cold
-
BUT, 8 days equal about 29% of the days in a usual menstrual cycle THUS
29% of these behaviors should occur during these 8 days. Behaviors left
to explain:
-
20% crimes
-
16% of calling in sick
-
17% psychiatric admissions
-
23% accident-emergency admissions
-
25% taking child to clinic for minor cold
-
AND
-
We know that STRESS can affect the hormonal cycle
-
thus bringing on the menstrual cycle.
-
No decrements have been found for physical or intellectual performance
during this 8-day period.
-
Retrospective Questionnaires--Report of symptoms and moods at various phases
-
Focus of Questions
-
Illusory Correlation
-
Social Conditioning
-
Self-Reports Made by Women Throughout Their Cycle
-
Positive mood around the time of ovulation
-
Anxiety, irritability, depression, fatigue, and headaches premenstrually
-
Problems with Self-Reports
-
Demand Characteristics
-
Negative findings disappear when respondents are not aware that PMS is
being studied
-
Projective Techniques
-
Participants tell stories to the experimenter at regular intervals throughout
the cycle
-
Stories premenstrually contain more anxiety about death, mutilation, and
separation
-
Stories midcycle (ovulation) contain higher levels of self-esteem and self-confidence
-
Problems with PMS Research
-
1. Virtually all data is correlational.
-
2. PMS is vaguely defined.
-
3. Documented cultural influences.
-
4. Subtle problem of interpretation
-
5. Failure to investigate effective coping techniques
-
Conclusions
-
that some women do experience cyclic mood changes but so do some men,
-
that these changes are primarily hormonal is not likely, and
-
that they are culturally determined is more likely, but NOT proved.
-
No matter what the source of these mood changes
-
they probably affect far less than 50% of women,
-
most women cope effectively with these changes by sleeping more or by keeping
busy or by eating foods that do not promote water retention, AND
-
these mood changes DO NOT affect physical and intellectual abilities,
i.e., work output is as high in quantity and quality as at any other time
of the month.
-
Documented Menstrual Cycle Fluctuations
-
Increased sensitivity of the senses
-
Menopause
-
Changes
-
sexual behavior
-
Decline in sexual interest
-
Painful intercourse
-
Hot Flashes, etc.
-
Periods of profuse sweating, feeling very hot, and becoming flushed
-
Associated with a surge of lutenizing hormone and/or increased adrenal
activity
-
Occur in 60-70% of women
-
Correlates of Hot Flashes
-
tingling sensations
-
insomnia
-
nervousness
-
muscle and joint aches
-
fatigue
-
dizziness
-
headaches
-
heart palpitations
-
Depression
-
About 30% of women who have had depression in the past will have
a small increase in the number of depressive episodes and the number
of depressive symptoms
-
These are related to the frequency of the hot flashes and to the women’s
feelings about her loss of fertility.
-
Women who have not had prior episodes of depression are not at increased
risk
of depression following menopause.
-
Etc.
-
Women are more likely to report distressing menopausal changes if they
are less educated, not working, and in poor physical health.
-
These changes will be reported as more distressing if either she or her
culture has a negative stereotype of postmenopausal women.
-
Having severe and/or frequent life stress, e.g., death, illnesses, retirement,
also increases distressing menopausal symptoms.
-
Osteoporosis
-
Loss of bone structure
-
Makes breakage more likely
-
Can lead to the "dowager’s hump"
-
Cigarette smoking, alcohol consumption, and low activity levels seem to
increase the rate of osteoporosis
-
Estrogen therapy, exercise, calcium supplements, and being slightly overweight
decrease the rate
-
Estrogen Replacement Therapy (aka HRT)
-
Although decreases the risk of osteoporosis and heart disease, it may increase
the risk of breast cancer
-
On many regimens the menses continue
-

MEN
Physical Changes
Spermarche
Hormonal Cycles
Circadian Cycles
Hormonal changes that regularly recur during each 24-hour period
For males the highest testosterone levels occur at night
-
Peaks in testosterone levels occur 30 to 10 minutes before REM
-
Related to adrenal activity not testes
-
Females also have testosterone cycles with the highest levels in the morning
-
Behavioral Correlates
-
Females
-
Orgasm most likely to occur when sexual activity takes place after midday
-
Males
-
Positive moods more likely at midday and late afternoon
-
Cognitive task performances better in the morning
-
Monthly Cycles in Males
-
Little research in this area
-
One study found monthly cycles in male mental patients
-
mental symptoms
-
activity levels
-
body temperature
-
incidents of fevers
-
Another study found rhythmic changes in testosterone levels
-
ranged from 8 to 30 days
-
consistent for each individual
-
varied from 9% to 28% change
-
again, consistent for each individual
-
Annual Cycles in Females
-
Ovarian activity seems to be suppressed during the winter
-
Annual Cycles in Males
-
Testosterone reaches a peak somewhere between July and November
-
younger men have earlier seasonal peaks
-
Lowest testosterone levels are between February and June
-
Possible Correlates with Annual Cycles
-
Small annual rhythms in several behaviors have been identified
-
Annual peaks in these behaviors generally occur between May and November
-
Reproductive Senescence
-
Aging males have declining levels of testosterone
-
Decline in level is evident by age 44
-
Estrogen levels may increase
-
particularly in males with higher levels of body fat
-
Changes in Sexual Behavior
-
Decline in testosterone is not directly related to decline in sexual activity
-
Injections of testosterone will not restore the sexual activity
of older males to levels typical of younger males
-
However, regular sexual activity may maintain youthful levels of testosterone
in older men
-
Testosterone Treatment
-
Androgen treatment for 45 to 60 year old males can lead to
-
a decrease in neuroticism
-
an increase in extroversion, and
-
an increase in masculine self-image
-
Improvements in cognitive performance have also been shown
-
Male Menopause
-
There are real problems with this work
-
More recent studies indicate this is a social/cultural phenomenon, not
a biological/hormonal factor.
