Monogamous
Definition:
(a.) Upholding, or practicing, monogamy.
(a.) Same as Monogamian.
(a.) Mating with but one of the opposite sex; -- said of birds and mammals.
Example Sentences:
(1) In two heterosexual couples, transmission of lymphadenopathy-associated virus from a seropositive man at increased risk to his monogamous wife occurred.
(2) Previous investigators have pointed to one-male mating systems, monogamous pair-bonding, or an arboreal habitat as reasons that some primates should have less conspicuous signals of estrus than others.
(3) The surveys also indicate that condom use declines with age, presumably because older respondents have formed monogamous relationships.
(4) Evidence for sexual transmission is provided by a significantly greater incidence of bacterial vaginosis in women with more than 5 sexual partners compared to those in a lifelong monogamous relationship, while bacterial detection in virgins and the failure to demonstrate benefits of partner treatment argue against sexual transmission.
(5) Those messages are: Any sexual intercourse (outside of mutually monogamous or HIV antibody-negative relationships) must be protected with a condom.
(6) We show that for many realistic situations the probability of becoming infected by multiple partners is equal to the probability of becoming infected by one partner in a monogamous relationship given that the prevalence is the same in both cases; however if the multiple partners are chosen over time from a pool of a growing prevalence, then one is better off in a monogamous relationship where that partner is chosen early in the epidemic.
(7) The relation between sex role self-concept (masculine, feminine, undifferentiated, and androgynous) and both relationship quality and dysfunctional relationship beliefs was examined in 370 monogamous partners who represented four types of couples (married, heterosexual cohabiting, gay, and lesbian).
(8) Everything else being equal, males of polygynous species are characterized by more variable canine sizes than males of monogamous species.
(9) Process evaluation allows identification of multipliers that reinforce and confirm the initial message of prevention (source) thereby encouraging behaviour modifications that are likely to reduce the transmission of HIV (condom use, no sharing of injection material, monogamous relationship, etc.).
(10) They also tended to be monogamous and avoided high risk groups.
(11) = 1.72), the results reveal that male adolescents from monogamous families experience better psychological adjustment than their polygynous counterparts, whereas no such difference exists in the levels of psychological adjustment of female adolescents from both family types.
