Menstrual Cycle Effects on Attitudes toward Romantic Kissing.
ABSTRACT Hormonal changes associated with the human menstrual cycle have been previously found to affect female mate preference, whereby women in the late follicular phase of their cycle (i.e., at higher risk of conception) prefer males displaying putative signals of underlying genetic fitness. Past research also suggests that romantic kissing is utilized in human mating contexts to assess potential mating partners. The current study examined whether women in their late follicular cycle phase place greater value on kissing at times when it might help serve mate assessment functions. Using an international online questionnaire, results showed that women in the follicular phase of their menstrual cycle felt that kissing was more important at initial stages of a relationship than women in the luteal phase of their cycle. Furthermore, it was found that estimated progesterone levels were a significant negative predictor for these ratings.

ABSTRACT: Signal detection measures olfactory sensitivity (d') and measures of blood pressure, heart rate, body temperature, nasal airflow, and respiration rate were repeatedly established within approximately 2.5-hr test sessions held every other day across 17 menstrual cycles of women not taking oral contraceptives, 6 menstrual cycles of women taking oral contraceptives, and 6 equivalent time periods of three men. In addition, radioimmunoassay-determined serum levels of luteinizing hormone, follicle stimulating hormone, estrone, estradiol, progesterone, and testosterone, as well as responses to the Moos Menstrual Distress Questionnaire (MDQ), were established daily or bidaily throughout the study periods. Peaks in olfactory sensitivity were noted during the second half of menses, midcycle, and midluteally in women taking and in women not taking oral contraceptives. The lack of correlation between the fluctuations in d' and the circulating hormone levels in the group using oral contraceptives suggests factors other than gonadal hormones were responsible for these changes. Significant fluctuations were also noted across the cycle phases of the normally cycling women for all the hormones examined, as well as for body temperature, nasal airflow, and the MDZ Water Retention and Pain Scales. In the oral contraceptive group, very small but statistically significant changes were observed across the cycle in body temperature and in circulating levels of luteinizing hormone and estrone. Interrelations between a number of the variables were noted both within and across the test periods in all three subject groups. The results are discussed in relation to fluctuations reported in a number of sensory systems during the menstrual cycle.Journal of Comparative and Physiological Psychology 03/1981; 95(1):45-60. · 1.96 Impact Factor

ABSTRACT: Halitosis in older adults is a common condition that may have oral or nonoral sources, result from a number of different etiologies, and have more than just social consequences. In some cases, bad breath may reflect serious local or systemic conditions, including gingivitis, periodontal disease, diabetic acidosis, hepatic failure, or respiratory infection. Your role as the primary care physician is first to determine whether the odor has an oral or nonoral cause. Odors can be distinct in their quality and thus can help make this determination. Management of nonoral sources requires treatment of the underlying cause, whereas suspected oral sources require referral for a dental evaluation.Geriatrics 09/1993; 48(8):55-9. · 1.35 Impact Factor
