| 11. | Human primary oocytes are present at an intermediate stage of meiosis, termed prophase I ( see Oogenesis ).
|
| 12. | In 1951 Zuckerman published his paper summarizing the existing data both for and against the possibility of postnatal oogenesis.
|
| 13. | One scientist has taken a time-lapse movie of egg formation, or oogenesis, in the fruit fly.
|
| 14. | Human primary oocytes are present at an intermediate stage of meiosis, that is prophase I ( see Oogenesis ).
|
| 15. | These substances act as an anti-aphrodisiac causing a dejection of subsequent copulations, and also stimulate ovulation and oogenesis.
|
| 16. | Insect sexual reproduction starts with sperm entry that stimulates oogenesis, meiosis occurs and the egg moves down the genital tract.
|
| 17. | The supply of immature egg cells in the ovaries is fixed during embryonic development, well before birth-see oogenesis.
|
| 18. | GDF9 is essential for the overall process of folliculogenesis, oogenesis and ovulation and thus plays a major role in female fertility.
|
| 19. | Since they are hermaphrodites, and they perform both oogenesis and spermatogenesis, I wonder how they split their chromosomes during meiosis.
|
| 20. | Oogenesis consists of several sub-processes : oocytogenesis, ootidogenesis, and finally maturation to form an ovum ( oogenesis proper ).
