Socially induced infertility: familial effects on reproductive development of female Mongolian gerbils

TLDR
The results suggest that age at first impregnation of female Mongolian gerbils living in family groups can be influenced by interactions with their sisters, dam and father, as well as with unfamiliar males.

Socially induced delayed reproduction in female Mongolian gerbils (Meriones unguiculatus): is there anything special about dominant females?

TLDR
It is indicated that maintaining young female gerbils in stable family groups results in both inhibition of sexual maturation and failure to activate sexual development (caused by lack of exposure to unfamiliar males).

Reproductive delay in the female Cape ground squirrel (Xerus inauris)

TLDR
It is found that 2 social parameters hold the most influence on the timing of female sexual maturity; specifically, the number of adult breeding female group mates and related adult male group mates were associated with a substantial inhibition of female reproductive maturity.

Social Cues Attenuate Photoresponsiveness of the Male Reproductive System in Siberian Hamsters (Phodopus sungorus)

TLDR
The results suggest that the inhibitory effects of long durations of melatonin secretion (in response to short photoperiods) on the male hypothalamic-pituitary-gonadal axis may be attenuated by social cues such as contact with the opposite sex.

Long-Term Reproductive Effects of a Single Long Day in the Siberian Hamster (Phodopus sungorus

TLDR
It is suggested that the long-term effects of acute light treatments on reproduction are mediated by sustained changes in melatonin secretion induced by reprogramming of circadian oscillators.

Influence of Cats’ Urinary Chemosignals on Sexual Maturation and Meiosis in Campbell’s Hamster Males ( Phodopus Campbelli )

TLDR
Data indicate that the disturbance of homologous synapsis at the first meiotic prophase may at least in part explain the decrease of epididymis weight in cat urine treated hamsters.

Role of social stimuli in the photoperiodic induction.

TLDR
The pairing in the environment appears to affect the gonadal growth in females but not in males, and the effects of social interaction on photoperiodic induction in house sparrows are studied.

Family composition and menarcheal age: Anti‐inbreeding strategies

TLDR
The present findings are suggestive of putative human pheromones that modulate sexual maturation to promote gene survival and prevent inbreeding, as occurs in rodents and nonhuman primates.

Social influences on androgen levels in the southern leopard frog, Rana sphenocephala.

TLDR
Results suggest that in addition to environmental cues such as rainfall and other seasonal changes, social cues may also serve as environmental synchronizers among anurans to coordinate reproductive effort.

Social mediation of puberty: an adaptive female strategy?

Photoperiod control of reproductive development in the male Djungarian hamster (Phodopus sungorus).

TLDR
The hypothesis that the short day-induced suppression of gonadotropins and PRL secretion during development blocked gonadal maturation in Djungarian or Siberian hamsters is supported.

Reproductive inhibition in female cactus mice (Peromyscus eremicus).

  • D. D. Skryja
  • Biology, Environmental Science
    Journal of mammalogy

Female Peromyscus eremicus born into freely growing populations generally failed to reproduce prior to 180 days of age, although asymptotic population size varied from nine to 27 among nine

The endocrinology of puberty and reproductive functioning in female cotton-top tamarins (Saguinus oedipus) under varying social conditions.

TLDR
The findings indicate that a suppression of fertility occurs in cotton-top tamarins living with their families, but that reproductive suppression does not affect the process of sexual maturation.

Social factors and puberty in female rats.

TLDR
The results do not support the view that in the rat pheromones from adult males enhance puberty in females, contrary to what is known to happen in the mouse.

Influence of pre- and post-copulatory pair contact on pregnancy success in Djungarian hamsters, Phodopus campbelli.

TLDR
The critical parameter responsible for the decrease in the number of females littering was the absence of the mate, irrespective of the presence or absence of a strange male.

Social influences on estrogen excretion and ovarian cyclicity in saddle back tamarins (Saguinus fuscicollis)

TLDR
It is concluded that ovarian estrogen production is suppressed and cyclicity does not occur as long as daughters live in their families, and chemical stimuli produced by the family may be involved in reproductive suppression.

Male-related pheromones and the activation of female reproduction in the prairie vole (Microtus ochrogaster).

TLDR
Sibling male-female pairs of this species do not ordinarily reproduce, but Estrus and subsequent reproduction were induced by applications of sibling male urine to the female’s upper lip, suggesting a behavioral barrier to reproduction among siblings.
