“…Relatively less research has explored heightened sense of smell or hyperosmia. But hyperosmia is important because, even if relatively rare, it is thought to be disruptive to normal functioning (e.g., Erick, 1995; Heinrichs, 2002; Nordin et al, 2005). …”

“…Six studies have examined the rating of odor hedonics in pregnancy (Gilbert and Wysocki, 1991; Laska et al, 1996; Kölble et al, 2001; Nordin et al, 2005; Swallow et al, 2005a; Cameron, 2007; Ochsenbein-Kölble et al, 2007). Gilbert and Wysocki (1991) reported that half of the odors they tested (galaxolide, eugenol, and mercaptans) were rated as significantly less pleasant by pregnant women and Kölble et al (2001) reported that pregnant women found cigarettes, coffee, and rum to be significantly less pleasant than controls, although there were no differences between the groups for hedonic ratings of other odors.…”

“…It is worthy of note that pyridine, which has a trigeminal component, was used as the stimulus in Olofsson et al’s (2005) study [and in the previously mentioned Broman et al’s (2003) study that showed significantly reduced thresholds in pregnancy] and it has been suggested that perceived hyperosmia may be related to trigeminal function (Nordin et al, 2005). In addition, pyridine is an unpleasant odor, which may also have been a factor in the outcome of these studies.…”

“…There is some evidence of this from questionnaire studies. Nordin et al (2005), 2007 found that pregnant women, particularly in the first trimester of pregnancy, score higher on the Chemical Sensitivity Scale for Sensory Hyperreactivity (Nordin et al, 2003). This lead the authors to conclude that “pregnant women to a large degree are affected by odorous/pungent substances in their daily activities” (Nordin et al, 2007, p. 341).…”

Many women report a heightened sense of smell during pregnancy. Accounts of these anecdotes have existed for over 100 years, but scientific evidence has been sparse and inconclusive. In this review, I examine the literature on olfactory perception during pregnancy including measures of self-report, olfactory thresholds, odor identification, intensity and hedonic ratings, and disgust. Support for a general decrease in olfactory thresholds (increase in sensitivity) is generally lacking. There is limited evidence that some suprathreshold measures of olfactory perception, such as hedonic ratings of odors, are affected by pregnancy, but these effects are idiosyncratic. In this review, I explore the hypotheses that have been put forth to explain changes in olfactory perception during pregnancy and provide suggestions for further research.

“…Embryo and maternal protective functions may affect this behavior . [7] Significant fluctuations were also noted for body temperature, nasal airflow across the cycle phases of the women with normal cycling for all the hormones examined. Fluctuations reported in some sensory systems during the menstrual cycle.…”

Pregnancy seems to be related with a significant change in olfaction. Here, we investigate this theory by testing the odor identification abilities of uncomplicated pregnant women and compare the results with non-pregnant controls. The study included 31 healthy pregnant women in the first trimester (Group 1), 30 in the second trimester (Group 2), 31 in the third trimester, and 30 non-pregnant healthy controls (Group 4). In order to measure odor identification abilities, each subject completed the 12-item Brief Smell Identification Test (BSIT). Next, the demographic characteristics and BSIT scores of the groups were compared. The total BSIT scores of the subjects in Group 1 were found to be significantly lower than those of the other groups (p < 0.001). This reduction in odor identification abilities was particularly noticeable for leather, pine, and soot. Pregnant women in the second and third trimesters had similar odor identification abilities to the healthy controls (p > 0.05). Early pregnancy might be related to significant changes in olfactory performance. The distortion of odor identification in the first trimester might be a causative factor for the development of pregnancy-specific conditions, such as morning sickness and hyperemesis gravidarum, which are both common complaints during the early phase of parturition.
