- Abstract:
- ... Fertility preservation is not only a concern for humans with compromised fertility after cancer treatment. The preservation of genetic material from endangered animal species or animals with important genetic traits will also greatly benefit from the development of alternative fertility preservation strategies. In humans, embryo cryopreservation and mature-oocyte cryopreservation are currently the ...

- Abstract:
- ... The objective of the present study was to describe ovarian activity in 11 adult non-mated guanacos, evaluated every second day for 40 days by transrectal ultrasonography and by plasma estradiol-17β and progesterone concentrations. An inverse relationship (r =−0.29, P <0.001) was observed between the diameter of the largest ovarian follicle and the total number of follicles indicating that follicul ...

Two field trials were conducted to determine the fertilising capacity of (i) frozen-thawed, sex-sorted re-frozen-thawed (FSF) dairy bull sperm inseminated close to the time of ovulation, (ii) FSF sperm following large dose insemination, and frozen-thawed, sex-sorted (FS) sperm inseminated within 12h after sorting. In Trial 1, 24 heifers in synchronised oestrus were observed for standing heat over ...

- Abstract:
- ... Previous research from our laboratory in beef cattle suggests that ovarian follicle maturity and subsequent fertility is influenced by length of proestrus across a range of follicle sizes. To test this hypothesis an animal model was used in which ovulation from similar sized follicles was induced following either a long (LPE; ∼2.25 days) or short (SPE; ∼1.25 days) proestrus (interval from PGF₂α ad ...

- Abstract:
- ... The use of the large pool of preantral follicles is a promising alternative to provide high numbers of fertilizable oocytes to reproductive biotechnology. This issue is particularly important to canids, since current rates of success of in vitro techniques using oocytes are very limited, and many species within this family are threatened by extinction. The aim of this study was to evaluate effects ...

- Abstract:
- ... The transition of a primordial follicle to a primary follicle is an early step in folliculogenesis. All female mammals are born with a fixed stock of primordial follicles, and exhaustion of that stock leads to menopause or infertility. Recently, several in vitro studies have indicated that BMP-4, BMP-7, and several other growth factors affect the transition of primordial to primary follicles. The ...

- Abstract:

Alterations in the ovarian micro-environment of females with follicular cysts could alter the normal processes of proliferation and programmed cell death in ovarian cells. Thus, the objective in the present study was to evaluate apoptosis and proliferation in induced ovarian cystic follicles in cows to investiga ...
