  Title Seminoma and parathyroid adenoma in a snow leopard (Panthera unica) Type Journal Article
  Year 1989 Publication J Comp Pathol Abbreviated Journal  
  Volume 100 Issue 4 Pages 475-480  
  Keywords Adenoma: pathology: veterinary; Animal; Carnivora; Dysgerminoma; pathology; veterinary; Male; Microscopy; Electron; neoplasms; Multiple Primary; Parathyroid; Testicular Neoplasms; adenoma; multiple; primary; Testicular; browse; 250  
  Abstract A seminoma and parathyroid adenoma were diagnosed in an aged snow leopard. The ultrastructural appearance of the seminoma was similar to that described in the dog and in man. The lack of significant amounts of rough endoplasmic reticulum, Golgi complexes and free ribosomes in the parathyroid adenoma suggested that it was non-functional. Parathyroid adenoma has not been previously described in a large wild feline.

  Title Seasonal effects on seminal and endocrine traits in the captive snow leopard (Panthera uncia) Type Journal Article
  Year 1994 Publication J Reprod Fertil Abbreviated Journal  
  Volume 102 Issue 1 Pages 229-236  
  Keywords Animal; Carnivora; physiology; Comparative; study; Fsh; Blood; Gonadotropins; Pituitary; Lh; Male; Seasons; Semen; Sperm; Motility; Spermatozoa; cytology; Testosterone; browse; 180  
  Abstract The annual reproductive cycle of the male snow leopard (Panthera uncia) was characterized by evaluating seminal and endocrine traits monthly. Testicular volume was greatest (P < 0.05) during the winter months when the quality of ejaculate was optimal. Ejaculate volume, total sperm concentration ml-1, motile sperm concentration per ejaculate, sperm morphology and sperm motility index were lowest during the summer and autumn months compared with the winter and spring. Peripheral LH, FSH and testosterone concentrations were also lowest during the summer months, increasing during the autumn just before the increase in semen quality, and were maximal during the winter months. There was a direct relationship (P < 0.01) between: (1) testosterone and testicular volume, total sperm concentration ml-1, motile sperm concentration per ejaculate and ejaculate volume, and (2) LH and testicular volume and motile sperm concentration per ejaculate. In summary, although spermatozoa were recovered throughout the year, optimal gamete quality was observed during the winter and spring. Although previous studies in felids have demonstrated seasonal effects on either seminal or endocrine traits, this is the first study to demonstrate a distinct effect of season on both pituitary and testicular function.

  Title Seasonal effects on ovarian responsiveness to exogenous gonadotrophins and successful artificial insemination in the snow leopard (Uncia uncia) Type Journal Article
  Year 1997 Publication Reprod Fertil Dev Abbreviated Journal  
  Volume 9 Issue 3 Pages 285-295  
  Keywords Animal; Carnivora; anatomy; histology; Blood; physiology; Estradiol; Female; Gonadotropins; administration; dosage; pharmacology; Chorionic; Equine; Human; Insemination; artificial; methods; veterinary; Laparoscopy; Male; Oocytes; cytology; Ovary; drug; effects; Ovulation; Induction; Pregnancy; Progesterone; Seasons; Support; Non-U.S.Gov't; browse; non; us; gov't; government; 400  
  Abstract Ovaries of the seasonally-breeding snow leopard (Uncia uncia) were examined to determine whether they were responsive to exogenous gonadotrophins throughout the year. The potential of laparoscopic artificial insemination (AI) also was assessed for producing offspring. During the non-breeding, pre-breeding, breeding and post-breeding seasons, females (n = 20) were treated with a standardized, dual- hormone regimen given intramuscularly (600 I.U. of equine chorionic gonadotrophin followed 80-84 h later with 300 I.U. of human chorionic gonadotrophin (hCG)). Laparoscopy was performed 45-50 h after administration of hCG, and all ovarian structures were described. Females with fresh corpora lutea (CL) were inseminated, and anovulatory females were subjected to follicular aspiration to examine oocyte quality. Snow leopards responded to exogenous gonadotrophins throughout the year. Mean number of total ovarian structures (distinct follicles mature in appearance plus CL) did not differ (P > or = 0.05) with season, but the proportion of CL: total ovarian structures was greater (P < 0.01) for the breeding season compared with all other seasons. The proportion of females ovulating was greater (P < 0.05) during the breeding and post-breeding seasons than during the pre-breeding and non- breeding seasons respectively. No Grade-1 quality oocytes were recovered from follicles of anovulatory females. Serum concentrations of oestradiol-17 beta appeared elevated in all females, and neither oestradiol-17 beta concentrations nor progesterone concentrations differed (P > or = 0.05) among seasons. Of 15 females artificially inseminated, the only one that was inseminated in the non-breeding season became pregnant and delivered a single cub. This is the first successful pregnancy resulting from AI in this endangered species.
