reproductive biology of the male sheath-tailed bat, taphozous longimanus (emballonuridae) from india.the seasonal chronological events of the reproductive cycle in the male sheath-tailed bat t. longimanus and changes in structure and function of accessory sex organs were studied at varanasi (latitude: 25 degrees n, 83 degrees e). the first peak of spermatogenesis was observed in september with the appearance of spermatozoa. the spermatogenic arrest in winter dormancy (december) was followed by a second peak of spermatogenesis in january. this period coincides with ovulation in females. the thir ...19979099423
seasonal changes in circulating testosterone and androstenedione concentration and their correlation with the anomalous reproductive pattern in the male indian sheath-tailed bat, taphozous longimanus.the relationship between reproductive organs, circulating testosterone, and androstenedione concentration in the male sheath-tailed bat, taphozous longimanus, was studied. the masses of testis, accessory sex gland (prostate, ampullary), and epididymides showed three peaks, one each in october, january, and april. monthly changes in testosterone also peaked during october, january, and april and closely coincided with the peak spermatogenesis. serum androstenedione concentration peaked during nov ...200010861550
seasonal changes in circulating steroid concentration and their correlation with the ovarian activity in the female indian sheath-tailed bat, taphozous longimanus.the relationship between ovarian activity and circulating steroid concentration was studied in the female sheath-tailed bat, taphozous longimanus. t. longimanus breeds twice in rapid succession during the year at varanasi, india. ovarian recrudescence was observed during september, and antral follicles were first observed during the month of october. circulating androstenedione concentration showed an increase beginning in october, reaching a peak in december. this increase in androstenedione co ...200211857472
changes in serum leptin, insulin, androstenedione and luteinizing hormone during ovarian cycle in the bat, taphozous longimanus.detailed reproductive pattern and associated endocrine characteristics have been documented in only a few species of order chiroptera. the aim of the present study was to examine the changes in body weight, serum insulin, leptin, androstenedione and luteinizing hormone (lh) concentrations during annual ovarian cycle in the sheath-tailed bat, taphozous longimanus. bats were sampled over three years. leptin, a satiety hormone produced primarily by adipose tissue, provides information to feeding ce ...200818401941
histochemical observations on the ovaries of some indian bats.ovarian follicles of the three species of bats, pteropus giganteus giganteus, taphozous longimanus and megaderma lyra lyra were studied with regard to the distribution and nature of mucopolysaccharides. oocyte contained only glycogen. zona pellucida showed the presence of glycogen, neutral mucosubstances, sialo- and sulfomucins. follicle cells showed the presence of glycogen and sialic acid except in megaderma lyra lyra where the follicle cells of the graafian follicle showed the presence of sul ...19806451992
histochemical observations on the female reproductive tract of bats. iii. mucosubstances in the fallopian tube of three species of bats.the epithelium of the three species of bats studied shows the presence of ciliated and nonciliated cells both in the ovarian and uterine segments of the fallopian tube of the functional uterine horn. the cytoplasm of these two cells types shows small amount of glycogen during anestrus, the amount increasing during proestrus and estrus. at estrus, the nonciliated cells show the presence of neutral and sialomucins in addition to glycogen in pteropus giganteus giganteus and megaderma lyra lyra. the ...19807203263
histochemical observations on the female reproductive tract of bats. iv. mucopolysaccharides in the uterus of three species of bats.the three species of bats studied show glycogen, neutral, sialo- and sulfomucins in the cells of the uterine epithelium and glands. elaboration of these mucins occurs during anestrus in pteropus giganteus and during proestrus in taphozous longimanus. in megaderma lyra lyra only glycogen is observed during anestrus and proestrus. neutral, and sialomucins in addition to glycogen are observed during estrus. the concentration of these mucins increases progressively and is maximum at the time of impl ...19816453476
seasonal changes in thyroid activity in the female sheath-tailed bat, taphozous longimanus (chiroptera: emballonuridae).the present study was designed to investigate changes in thyroid activity during the reproductive cycle in taphozous longimanus. thyroid gland showed marked seasonal variation in weight and secretory activity. it was inactive in quiescence and early to mid-winter dormancy and active during recrudescence and breeding period during late winter dormancy. the serum 3,5,3'-triiodothyronine (t3) and thyroxine (t4) concentrations showed significant variation and closely coincided with thyroid activity. ...200212371606
