Follicular Development and Oocyte Growth
Follicular development begins as early as the fourth month of fetal life [1]. At that time, the primordial germ cells (PGCs) have migrated from the yolk sac endoderm to the gonadal ridge, undergoing mitotic divisions. PGCs are called oogonia once they reach the gonads, then the oogonia enter the first meiotic division and become primary oocytes. Somatic cells originating from the primitive gona...
متن کاملRelationship between growth hormone concentrations in bovine oocytes and follicular fluid and oocyte developmental competence.
In the last few years, several works suggest that Growth Hormone (GH) is involved in follicular development and oocyte maturation. These actions may reflect endocrine roles of pituitary GH and also account for local autocrine or paracrine activities of GH produced in reproductive tissue. This study was aimed to verify whether the developmental competence of bovine female gametes might be relate...
متن کاملthe relationship between collocational competence and listening comprehension
پس از پیدایش روش تدریس tpr توسط جیمز اشر که توجه و تآکید بسیاری بر مهارت شنیداری داشت زبانشناسان همواره در صدد یافتن راههایی برای بهبود این مهارت در زبان آموزان می باشند. از طرفی جی-آر-فرث که از پیشگامان زبانشناسی می باشد بر تآثیر لغات و بویژه گروه کلمات که اغلب در گفتار با هم می آیند (هم آیی کلمات)تأکید بسیار کرده است. به این دلیل و به منظوربررسی رابطه بین این دو عامل یعنی درک شنیداری و دانش...
15 صفحه اولThe mammalian oocyte orchestrates the rate of ovarian follicular development.
The development of both the mammalian oocyte and the somatic cell compartments of the ovarian follicle is highly coordinated; this coordination ensures that the ovulated oocyte is ready to undergo fertilization and subsequent embryogenesis. Disruption of this synchrony results in oocyte developmental failure. Communication between the oocyte and companion somatic cells is essential for successf...
متن کاملO-10: Assessment of Oocyte and Embryo Quality in Different Time between Oocyte Retrieval and hCG Priming
Background: Abnormal oocyte morphology has been associated with the hormonal environment to which the gametes are exposed. In this study, we evaluated the oocytes morphology, fertilization rate, embryos quality, and implantation rate resulted of retrieved oocytes in different times after human chorionic gonadotrophin (hCG) administration. Materials and Methods: A total of 985 metaphase II were ...
