  • fertility
  • It received an approval for female fertility with the main function of inducing the final stage of maturation of the follicles. (absoluterx.com)
  • For children in puberty, the standard forms of fertility preservation (sperm cryopreservation for boys and egg and oocyte cryopreservation for girls) are offered in all circumstances wherein fertility may be adversely impacted due to gonadotoxic chemotherapy or radiation. (mayoclinic.org)
  • Ovarian tissue cryopreservation can also impact fertility preservation options for those postpubertal girls who are unable to undergo egg cryopreservation due to an inability to delay treatment for up to two weeks or for whom there is a contraindication to the hormonal stimulation required to harvest oocytes. (mayoclinic.org)
  • In vitro follicle techniques provide a tool to model follicle development in order to investigate basic biology, and are further being developed as a technique to preserve fertility in the clinic 1-4 . (jove.com)
  • semen
  • Throughout these industries, there are no strict guidelines as to the in vitro handling methods for these procedures, leading to the question of whether different in vitro conditions influence the outcomes of semen analyses and ultimately if this impacts upon clinical decision making. (edu.au)
  • Consequently, this project aims to quantify the differences in semen analysis results when semen is exposed to a variety of different in vitro handling techniques. (edu.au)
  • recombinant
  • The in vitro fusion of GENES by RECOMBINANT DNA techniques to analyze protein behavior or GENE EXPRESSION REGULATION, or to merge protein functions for specific medical or industrial uses. (bioportfolio.com)
  • In oocytes from hibernation-interrupted toads, the p34(cdc2) protein level was significantly lower than in oocytes from toads in artificial hibernation, providing an explanation for the different quantities isolated by recombinant tUCHL1 pull-down and, more importantly, identifying a mechanism involved in the toad oocytes dependence on a low environmental temperature during winter hibernation.

  • underwent
  • Women who underwent oocyte retrieval at our institution between August 1995 and February 1997 and agreed to participate in the study were enrolled consecutively. (thefreedictionary.com)
  • retrieval
  • Therefore, it can be used to promote the start of oocyte maturation, when given as a trigger prior to oocyte retrieval. (cochrane.org)
  • However, even when only a single follicle is punctured, oocyte retrieval can be painful. (thefreedictionary.com)
  • For each cycle, men whose female partner was undergoing IVF or IUI provided one spot urine sample at the time of oocyte retrieval or insemination, respectively. (thefreedictionary.com)
  • From a medical standpoint, this case of postmortem oocyte retrieval is fraught with difficulty. (thefreedictionary.com)
  • Comparison of different transvaginal ovum pick-up protocols to optimise oocyte retrieval and embryo production over a 10-week period in cows. (thefreedictionary.com)
  • The drops were prepared in Falcon #3002 Petri dishes (Becton-Dickinson Labware, Lincoln Park, NJ) one to three hours prior to oocyte retrieval with media that were equilibrated overnight in a 36. (thefreedictionary.com)
  • follicle
  • This was an open, randomized, comparative study using rhCG (Ovidrel) in the induction of final follicle maturation and early luteinization in Chinese female subjects undergoing IVF or ET. (bioportfolio.com)
  • Two different experiments were conducted to investigate the effect of KP (5, 10 and 15 μg/ml) alone (experiment 1) or in combination with follicle-stimulating hormone (FSH), luteinizing hormone (LH), and Estradiol (E 2 ) (experiment 2) on IVM of sheep oocytes. (veterinaryworld.org)
  • Our in vitro culture system employs hydrogels in order to mimic the native ovarian environment by maintaining the 3D follicular architecture, cell-cell interactions and paracrine signaling that direct follicle development 5 . (jove.com)
  • germ cells
  • Together, these methods allow researchers to study how germ cells become competent for fertilization in diverse animals and also explain how to visualize and assay the biochemical mechanisms associated with normal fertilization. (biologists.org)
  • ultrastructural
  • The oocytes were collected as described in study I. After appropriate slide fixation and preparation, the material was analyzed for morphological and ultrastructural characteristics and photographed. (vin.com)
  • No ultrastructural differences were seen in oocytes of adult and young cats. (vin.com)
  • methods
  • However, in addition to in situ conservation, methods or techniques to maintain live animals outside their production or natural environment (ex situ live) or through cryopreservation of germplasm (ex situ) are set up to preserve (germplasm of) rare breeds as well as the more widely used commercial breeds.
