Activation and Development of Marmoset Oocytes Exposed to Ethanol
Twenty percent (8 of 40) of oocytes exposed to ethanol were activated. Three types of development after activation were observed. Five (63%) activated oocytes underwent IC and had divided to 2 cells within 6-18 h of treatment; two oocytes (25%) were 2PB,1PN; and one oocyte was 1PB,2PN. Only the oocytes that underwent IC divided in culture. One of these embryos developed to 16 cells, one to 6 cells, one to 3 cells, and two to 2 cells in vitro. Overall, the average cell number (± SEM) of ethanol-activated par-thenogenones was 4.0 ± 1.7. This was not significantly different from the average cell number reached by electrically stimulated parthenogenetic embryos. buy yasmin online
None of the control oocytes (0 of 19) were partheno-genetically activated.
Progesterone Profiles of Recipient Marmosets
Normal serum progesterone profiles for pregnant and nonpregnant marmosets have been reported previously. Briefly, in a normal nonpregnant cycle, progesterone levels rise above 10 ng/ml on the day after ovulation, increase to 50-100 ng/ml until 16-18 days after ovulation (the end of the luteal phase), and drop to baseline.
