endocrine/exocrine glands
• the bulbourethral gland is smaller than normal
|
• the seminal vesicles are smaller than normal
|
• preovulatory follicles and healthy antral are absent
|
• primary and secondary follicles appear normal, whereas many antral follicles are abnormal and contain degenerating oocytes
• however, ovarian histology reveals a normal thecal layer, although expression of various thecal cell markers is significantly reduced
|
small ovary
(
J:94719
)
• the ovaries are smaller than normal
|
ovary cyst
(
J:94719
)
• occasional non-hemorrhagic cysts are found
|
• no mature Leydig cells are found in the interstitium of mutant testes
• instead, three distinct types of Leydig cells are observed, classified as fetal-like, spindle shaped progenitors and small round immature Leydig cells
|
• very few small-size Leydig cells are present and those seen are mostly fetal Leydig cells
(J:94719)
• presence of fetal Leydig cells is confirmed by increased serum levels of the androgen precursor, androstenedione
(J:122322)
|
small testis
(
J:94719
)
• the testes are smaller than normal
|
growth/size/body
ovary cyst
(
J:94719
)
• occasional non-hemorrhagic cysts are found
|
homeostasis/metabolism
• serum and testicular testosterone levels are decreased in males and androstenedione, a testosterone precursor, levels are increased
|
• serum estradiol levels are decreased in females
• however, serum FSH levels remain unaffected
|
• serum progesterone levels are decreased in females
|
reproductive system
• preovulatory follicles and healthy antral are absent
|
• primary and secondary follicles appear normal, whereas many antral follicles are abnormal and contain degenerating oocytes
• however, ovarian histology reveals a normal thecal layer, although expression of various thecal cell markers is significantly reduced
|
ovary cyst
(

)
• occasional non-hemorrhagic cysts are found
|
small vulva
(
J:94719
)
• the external female genitalia are smaller than normal
|
(J:94719)
• mutant uteri are hypoplastic with a thin endometrial layer
(J:122322)
|
• only degenerating oocytes are found; however, when superovulated mutant females release comparable numbers of ova to untreated wild-type mice
|
(J:94719)
• no sperm are present in mutant testes
(J:122322)
|
• no late stage or elongated spermatids are observed, consistent with an absence of histone H1-like linker protein (a late stage spermatid marker suppressed in mutant testes)
|
• spermatogenesis arrests at the round spermatid stage
(J:94719)
• only type B spermatogonia, pachytene spermatocytes and round spermatids are identified in mutant testes, whereas late stage spermatids and sperm are clearly absent
(J:122322)

(J:122322)
|
• the external male genitalia are smaller than normal
|
• mutants display postnatal defects in gonad growth and differentiation

small testis
(

|
infertility
(
J:94719
)
• both males and females are sterile
|
cellular
