Laser-assisted hatching of cryopreserved-thawed embryos by thinning one quarter of the zona
(2006-11-01)
Laser-assisted hatching is little documented in the literature regarding its efficacy in cryopreserved-thawed (CT) embryo transfer cycles. The aim of the present study was to evaluate in a randomized manner the efficacy ...
Pregnancy rate after fixed-time transfer of cryopreserved embryos collected by non-surgical route in Lacaune sheep
(2019-01-01)
This study investigated the feasibility of applying fixed-time (cryopreserved) embryo transfer in ewes. Embryos (n = 106) were non-surgically recovered from superovulated donors (n = 39) on day 6–7 after oestrus. Straws ...

(2020-04-01)
Objective: This paper looked into the findings of a survey on the ethical and emotional aspects encircling the fate of surplus embryos in Assisted Human Reproduction (AHR). Methods: Five staff members of a fertility clinic ...

Heat or cold chronic stress affects organ weights and Hsp70 levels in chicken embryos
(Agricultural Inst Canada, 2001-03-01)
This study was carried out with the objective of evaluating the effect of heat (38.8 degreesC) or cold (35.8 degreesC) stress on chicken embryo development and tissues Hsp70 levels, after the 13th day of incubation. Embryo ...
Sexing of murine and bovine embryos by developmental high-titer arrest induced by H-Y antisera
(Elsevier B.V., 2004-12-01)
Murine and bovine embryos at the late morula stage were cultured in medium containing high-titer rat H-Y antisera. After 12 h of incubation, embryos blocked at the late morulae stage were classified as males and those at ...
Polyembryony increases embryo and seedling mortality but also enhances seed individual survival in Handroanthus species (Bignoniaceae)
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-01-01)
Polyembryony seems to be advantageous to mother plants in detriment of their siblings which face competition since the beginning of seed development. This competition may limit the turnover of embryos into seedlings and ...
