生殖过程中,免疫系统和内分泌系统均发生明显的改变。但妊娠期激素水平在质和量方面的显著变化对母体免疫系统的影响并不清楚。已知,精浆中含有一些免疫抑制物,可保护精子防止受到局部免疫反应的袭击。但对精子在免疫学上异体的雌性生殖道中的存活,雌性激素有何影响则所知甚少。显然,精子在女性体内运行的72小时中,所接触的环境富于由卵巢分泌的孕酮。当卵子受精后,合子将植入子宫内膜。通常,精密地取决于卵巢雌激素和孕酮准备的植入过程伴有明显的蜕膜反应。蜕膜细胞是在对父系或胚胎抗
Reproductive process, the immune system and the endocrine system have undergone significant changes. However, the effects of significant changes in quality and quantity of hormone levels during pregnancy on the maternal immune system are not clear. It is known that seminal plasma contains some immunosuppressants that protect sperm against attacks by the local immune response. However, little is known about the effects of estrogen on the survival of sperm in the immunocompromised female reproductive tract. Obviously, the spermatozoa are exposed to progesterone secreted by the ovary in 72 hours of operation in women. When the egg is fertilized, zygotes are implanted in the endometrium. In general, the decidua reaction, which depends critically on the engraftment of ovarian estrogen and progesterone preparations, is accompanied by a marked decidual reaction. Decidual cells are resistant to paternal or embryo
