Analysis of the estrous cycle of the laboratory-housed Senegal galago (Galago senegalensis senegalensis): natural and induced cycles. 1982

K J Darney, and L E Franklin

The natural estrous cycle of captive Senegal galagos was analyzed from daily records of 11 cycling females for 18 months, and induction of vaginal estrus and ovulation by gonadotropins and estrogen were examined in 9 females. No seasonal trend in cycling was indicated, as at least 5 of the 11 cycling females exhibited vaginal estrus during each month. Cycle lengths and duration of estrus were consistent for each female but varied significantly among females. Individuals' average cycle lengths ranged from 29.2 +/- 0.8 to 39.3 +/- 3.4 days, and duration of estrus from 4.8 +/- 0.2 to 6.7 +/- 0.4 days. Vaginal estrus was induced by PMSG and PMSG-HCG combinations, and by estradiol. The gonadotropins also induced growth and ovulation of more than one follicle.

D005701 Galago A genus of the family Lorisidae having four species which inhabit the forests and bush regions of Africa south of the Sahara and some nearby islands. The four species are G. alleni, G. crassicaudatus, G. demidovii, and G. senegalensis. There is another genus, Euoticus, containing two species which some authors have included in the Galago genus.

D006063 Chorionic Gonadotropin A gonadotropic glycoprotein hormone produced primarily by the PLACENTA. Similar to the pituitary LUTEINIZING HORMONE in structure and function, chorionic gonadotropin is involved in maintaining the CORPUS LUTEUM during pregnancy. CG consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is virtually identical to the alpha subunits of the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity (CHORIONIC GONADOTROPIN, BETA SUBUNIT, HUMAN).

D006064 Gonadotropins, Equine Gonadotropins secreted by the pituitary or the placenta in horses. This term generally refers to the gonadotropins found in the pregnant mare serum, a rich source of equine CHORIONIC GONADOTROPIN; LUTEINIZING HORMONE; and FOLLICLE STIMULATING HORMONE. Unlike that in humans, the equine LUTEINIZING HORMONE, BETA SUBUNIT is identical to the equine choronic gonadotropin, beta. Equine gonadotropins prepared from pregnant mare serum are used in reproductive studies.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
