  • receptive
  • In a stimulated or a cycle where a "frozen" embryo is transferred, the recipient woman could be given first estrogen preparations (about 2 weeks), then a combination of oestrogen and progesterone so that the lining becomes receptive for the embryo. (wikipedia.org)
  • vitro fertilization
  • While comprehensively covering subjects such as the molecular mechanisms of embryonic development, in vitro fertilization, cloning, and the laws and ethical considerations of working with embryos, the volume also addresses critical features of fetal and placental development as well as of uterine biology. (springer.com)
  • defects
  • The outcome from using cryopreserved embryos has uniformly been positive with no increase in birth defects or development abnormalities, also between fresh versus frozen eggs used for intracytoplasmic sperm injection (ICSI). (wikipedia.org)
  • Ablation in female mice results in subfertility, with defects in implantation and decidualization. (wikipedia.org)
  • Embryos who reach the day 3 cell stage can be tested for chromosomal or specific genetic defects prior to possible transfer by preimplantation genetic diagnosis (PGD). (wikipedia.org)
  • developmental
  • Roth and Padilla, the paper's co-author, compared the developmental capability of zebrafish embryos that had been exposed to normal atmospheric conditions to those grown in anoxic (oxygen-free) chambers. (fredhutch.org)
  • transfer
  • In a natural cycle the embryo transfer takes place in the luteal phase at a time where the lining is appropriately undeveloped in relation to the status of the present Luteinizing Hormone. (wikipedia.org)
  • Because of increased female embryo mortality due to epigenetic modifications induced by extended culture, blastocyst transfer leads to more male births (56.1% male) versus 2 or 3 day transfer (a normal sex ratio of 51.5% male). (wikipedia.org)
  • The embryo transfer procedure starts by placing a speculum in the vagina to visualize the cervix, which is cleansed with saline solution or culture media. (wikipedia.org)
  • A soft transfer catheter is loaded with the embryos and handed to the clinician after confirmation of the patient's identity. (wikipedia.org)
  • post fertilization
  • The researchers found that embryos 25 hours post-fertilization or younger could survive without oxygen for 24 hours and resume normal development after re-exposure to standard levels of oxygen. (fredhutch.org)
  • placentas
  • Laparotomy was performed on the 21 st day of pregnancy, followed by the determination of reproductive variables: number of live and dead fetuses, mass of the fetuses and placentas, number of implantations and resorptions, number of corpora lutea, pre- and post-implantation loss, and analyses of the fetuses with regard to external and internal anomalies and/or malformations (skeletal and visceral). (thefreelibrary.com)
  • These two events led to embryo death or delayed embryonic development and hypertrophic placentas shared by multiple embryos. (nii.ac.jp)
  • Birth
  • If mast crops are poor and the sow does not have the fat reserve necessary to support herself and young, sows may re-absorb the embryo and not give birth that year. (nps.gov)
  • If she does not have enough stored energy, she will reabsorb the embryo and will not give birth that year. (fairmonthotsprings.com)
  • reproductive
  • a process of particular importance) Poor implantation rate is a major problem during infertility treatments using assisted reproductive technologies (ART). (nii.ac.jp)
  • Evaluation
  • Evaluation of delayed puberty usually reveals the presence of pubic hair, but elevation of gonadotropins, indicating that the pituitary is providing the signal for puberty but the gonads are failing to respond. (wikipedia.org)
  • further
  • These data identify LPA_3 receptor-mediated signaling as a new influence on implantation and further indicate linkage between LPA signalling and prostaglandin biosynthesis. (nii.ac.jp)
