Mature females may present previtellogenic, vitellogenic and
atretic follicles, and corpora lutea.
Thus, according to study results, it can be concluded that waves emitted from mobile phones may reduce the number of secondary and Grapian follicles by interfere in controlling routines and also increase the
atretic follicles that can have adverse effect on fertility of female rats.
In addition, ovaries from BPA500 animals had fewer corpora lutea, fewer antral follicles, and more
atretic follicles than did those from controls.
Surgical reconstruction of the congenitally
atretic cervix: Two cases.
Throughout the year
atretic oocytes were observed (<1%) (Fig.
To determine if
atretic process is affected by the hor- monal status of the host,
atretic primary and secondary follicles were morphologically discriminated (Fig.
The gametogenic cycle in bivalves includes development and maturation of gametes, spawning, and subsequent resorption of residual
atretic gametes (Kennedy & Battle 1964, Pipe 1987, Dorange & Le Pennec 1989, Barber 1996).
Three cases had CNS anomalies (corpus callosum anomaly and
atretic occipital encephalocele) (Figure-2 and 3).
The
atretic follicles were present throughout the year but they were abundant during autumn (spent ovaries) and winter (resting ovaries) and these
atretic follicles indicated the spawned individuals.
Degenerating female follicle and
Atretic oocytes were clearly detected in post-spawned P.
Dural herniation with
atretic brain tissue excised and dura was closed.
Jegede [6] further investigated the control of reproduction in Oreochromis niloticus using Hibiscus rosa-sinensi (Linn) leaf meal as reproduction inhibitor and showed disintegration of spermatids and necrosis in testes and severe
atretic follicles in ovaries at a high inclusion level of 4.0 g/kg diet.
