“…(7) Scent marking after ejaculation Scent marking by the male is probably a hormonal phenomenon and appears to indicate the finish of mating behavior. It is under control of the genital gland (Balakrishnan et al ., 1984;Rissman and Bronson, 1987;Tennant et al ., 1987). Conversely, the female squats after ejaculation and maintains receptivity when the male touches her.…”

-In the present study, inter-male interaction of the domesticated house musk shrew was observed in detail under laboratory conditions. In most cases, during inter-male interaction, male house musk shrews exhibited a sequence of behavior items including tail-wagging, following, mounting and thrusting. In the minority of cases, males did not progress beyond following. Offensive behavior was not sufficiently violent to cause injury. It appeared that role assignment was decided by contact manner and vocalization. One of fundamental characters of this animal made a start of following, in which one shrew followed another, who touched and then separated. Role assignment (i.e., which male led and which followed) was decided in status battle. Roles were often reversed during following. Following behavior was maintained by 'polite' mutual contact, and the interaction progressed to thrusting in the majority cases. After role assignment, the variation in contact manner decreased. The ratio of time spent in front-andbehind contact to that spent in multi-lateral contact increased when both males commenced following behavior simultaneously. This ratio was maintained until the following male snapped after he finished thrusting. Even if the following male did not reach thrusting, he mounted the preceding male. The pairs who did not reach thrusting repeated following behavior or mounting. In those cases, while one male concentrated on touching the other to maintain following, the other attempted to divert attention from the following behavior. Male shrews were able to reach thrusting irrespective of sex.

“…Scent marking behaviour of Suticus murinus viridescens has been studied previously (Balakrishnan 1975, Balakrishnan and Alexander 1976, Balakrishnan et al 1984. Their specialized integumentary glands play a major role in olfactory communication during various social interactions (Balakrishnan and Alexander 1980).…”

“…A stimulatory effect of progesterone on male sexual behaviour is in contrast to reports on the behavioural effects of progesterone in male ver¬ tebrates. The only exception to this rule we are aware of is the apparent reinstatement of scent-marking behaviour by progesterone in male musk shrews (Balakrishnan, Shelly & Alexander, 1984); however, it should be noted that the behaviour restored in musk shrews is a small portion of the entire sexual reper¬ toire. In C. inornatus the entire range of sexual behav¬ iour is restored by exogenous progesterone, including intromission.…”

Effects of progestins on sexual behaviour in castrated lizards (Cnemidophorus inornatus)

In many male vertebrates, androgens stimulate, while progesterone inhibits, sexual behaviour. Testicular androgens also control sexual behaviour in males of the lizard Cnemidophorus inornatus. However, administration of progesterone will reinstate sexual behaviour in castrated animals. Increased doses of progesterone did not result in increased numbers of responders; at all doses tested approximately 36% (n = 45) of animals treated with progesterone responded as reliable courters. A high percentage (60-68%) of progesterone-sensitive individuals maintained their sensitivity over a period of months. A synthetic progestin 17,21-dimethyl-19-nor-4,9-pregnadiene-3,20-dione with low rates of metabolism and conversion, also stimulated sexual behaviour in castrated C. inornatus. Finally, the synthetic antiprogestin 11 beta-4-dimethylaminophenyl-17 beta-hydroxy-17 alpha-1-propinyl- 4,9-oestradiene-3-one inhibited the stimulatory effects of progesterone on sexual behaviour but failed to inhibit the stimulatory effects of androgens. These findings indicate an unusual departure from the characteristic pattern of steroid sensitivities of neural centres controlling sexual behaviour.
