Does Each Menstrual Cycle Elicit a Distinct Effect on Olfactory and Gustatory Perception?

Women followed across a complete menstrual cycle displayed a cyclic pattern characterized by a predilection for sweet solution; reduced distaste for salty and sour solutions; and increased intensity perception of salty, sour, and bitter solutions towards the end of the cycle.

Women Have Reduced Ability to Discriminate Body Odors During the Withdrawal Period of Oral Contraception

Women have reduced ability to discriminate body odors during the withdrawal period of oral contraception, and if women indeed consider men’s body odor in their mate selections, then the oral contraception withdrawal period may not be the best time to make such decisions.

Menstrual Cycle Phase and Duration of Oral Contraception Intake Affect Olfactory Perception

The data show that odor performance is affected by menstrual cycle phase and duration of oral contraception intake and thus can be modulated by hormonal changes.

Changes in Basal Body Temperature and Simple Reaction Times during the Menstrual Cycle

Results obtained in this study indicate lower basal body temperature values during phases with low sex hormone levels, while the activation assessments suggest stable levels of both General and High Activation throughout the menstrual cycle.

Olfaction During Pregnancy and Postpartum Period

These findings support the view that pregnancy-related alterations in smell are idiosyncratic, present only for some odorants, and may be impacted by the presence of rhinitis that commonly occurs during pregnancy.

The Amelioration of Olfactory Acuity upon Sexual Maturation Might Affect Food Preferences

Olfactory amelioration during ovulation might concur to a mating strategy, whereas olfactory impairment during bleeding might protect women against self-refusal and provoke a change in food preferences, for instance a reduction in fish consumption.

Olfactory processing and odor specificity: a meta-analysis of menstrual cycle variation in olfactory sensitivity

The results indicate that olfactory sensitivity may be a non-adaptive by-product of the general physiological fluctuations or differences in neural processing experienced across the cycle to a broad spectrum of odorants, rather than being specifically selected for mate choice-related odors.

Influence of Sexual Hormones on Neural Orofacial Perception

Estrogen and progesterone seem to be involved in sensory neuromodulation in women during the menstrual cycle, and thresholds for sweet, salty, sour, cold, vibration, and deep pain decreased, but warmth, electrical, and superficial pain thresholds increased.



Changes in olfactory perception during the menstrual cycle

Only with regard to androstenone did trend analyses reveal a significant quadratic relationship between hedonic estimates and phases of the menstrual cycle, peaking at ovulation.

Endocrine, cardiovascular, and psychological correlated of olfactory sensitivity changes during the human menstrual cycle.

Signal detection measures olfactory sensitivity (d') and measures of blood pressure, heart rate, body temperature, nasal airflow, and respiration rate, as well as responses to the Moos Menstrual Distress Questionnaire (MDQ), were established throughout the study periods and fluctuations reported in a number of sensory systems during the menstrual cycle are discussed.

Cyclical changes in olfactory and auditory sensitivity during the menstrual cycle: no attenuation by oral contraceptive medication.

This study demonstrates cyclic changes in olfactory sensitivity to phenyl ethyl alcohol and in auditory function in 2 consecutive cycles of a women taking OCs, indicating that menstrual cycle-related sensitivity changes in at least 2 major sensory modalities are not directly dependent upon circulating levels of primary reproductive hormones.

Perception of HLA-Related Body Odors During the Course of the Menstrual Cycle

In the present study chemosensory event-related potentials (CSERP) were used to find objective evidence that body odor and the perception of body odor by females is related to the similarity of the

Olfactory perception thresholds in hypogonadal women: changes accompanying administration of androgen and estrogen.

Olfactory perception thresholds and nasal mucous membrane function were measured over prolonged periods in 3 hypogonadal females and there was a tendency toward pallor and swelling of the nasal membranes in the hypog onadal group.

Menstrual cycle variation in women's preferences for the scent of symmetrical men

Normally cycling women near the peak fertility of their cycle tended to prefer the scent of shirts worn by symmetrical men, while normally ovulating women at low fertility within their cycle, and women using a contraceptive pill showed no significant preference for either symmetrical or asymmetrical men's scent.

Olfactory sensitivity during the menstrual cycle.

Women were tested for sensitivity to several odorants at ovulation and menstruation and three involatile esters predicted by gas chromatographic data to be strongly retarded by the olfactory mucus showed similar significant changes in sensitivity.

Effects of hormone replacement therapy on olfactory sensitivity: cross-sectional and longitudinal studies

Although prophylactic HRT has been suggested to be associated with improved olfactory function, it is found that its use in healthy postmenopausal women does not enhance performance in a wide range of Olfactory tasks.

Determinants of measured olfactory sensitivity

The results indicate that thresholds gathered in customary brief testing will underestimate olfactory sensitivity and overestimate individual differences.
