Side of ovulation and cycle characteristics in normally fertile women.

Relationships between the luteinizing hormone surge and other characteristics of the menstrual cycle in normally ovulating women.

OBJECTIVE To describe the LH surge variants in ovulating women and analyze their relationship with the day of ovulation and other hormone levels. DESIGN Secondary analysis of a prospective cohort observational study. SETTING Eight natural family planning clinics. SUBJECTS Normally fertile women (n = 107) over 283 cycles. INTERVENTION(S) Women collected daily first morning urine, charted...

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

Evidence suggests that female sexual preferences change across the menstrual cycle. Women's extra-pair copulations tend to occur in their most fertile period, whereas their intra-pair copulations tend to be more evenly spread out across the cycle. This pattern is consistent with women preferentially seeking men who evidence phenotypic markers of genetic benefits just before and during ovulation...

Humans differ from many other primates in the apparent absence of obvious advertisements of fertility within the ovulatory cycle. However, recent studies demonstrate increases in women's sexual motivation near ovulation, raising the question of whether human ovulation could be marked by observable changes in overt behavior. Using a sample of 30 partnered women photographed at high and low ferti...

Time of Ovulation in Women. A Study on the Fertile Period in the Menstrual Cycle

Frequency, sequence, and side of ovulation in women menstruating normally.

SHORT REPORTS Frequency, sequence, and side of ovulation in women menstruating normally Ovulation in the primate is usually regarded as a consistently alternating process that occurs with equal frequency in the right and left ovaries. We investigated whether ovulation in women occurs with equal frequency in each ovary, alternating consistently between the ovaries. Subjects, methods, and results...
