Ir-Inhibin Profiles of Recipient Marmosets
Previous studies have shown a significant difference in ir-inhibin levels between conception and nonconception cycles before implantation. During the first 26 days of gestation, animals 345W and 457W (IVF embryo recipients) had total ir-inhibin levels of 2.2 and 1.7 ug X days/ ml, respectively. The nonpregnant animal (323W) had a total ir-inhibin over the same 26 days of 1.4 ug X days/ ml. However, total ir-inhibin levels of 469W and 491W (parthenogenetic embryo recipients) during the first 26 days of gestation were 2.7 and 2.9 ug X days/ml, respectively. That is, the peripheral plasma ir-inhibin levels of the par-thenogenetic embryo recipients were 1.5 times higher than those of the IVF embryo recipients and 2 times higher than those of the nonpregnant animal. birth control yasmin
Histology of Uteri after Biparental IVF Embryo Transfer
The in vivo morphology of the biparental IVF embryos was similar to that described previously. Cytotropho-blast displayed extensive but superficial attachment to the luminal surface of the endometrium, covering almost the entire uterine lumen. The chorionic membrane attached to the luminal endometrium and the developing fetus with am-niotic sac was clearly visible.
