Implantation happens at 6–7 days after conception and involves the embedding of the growing embryo into the mothers uterus and a connection being formed. [2] A successful implantation can be determined by using an ultrasound to view the sac which the baby grows in, inside the uterus. [1] However, the exact definition of RIF is debated.
Levonorgestrel-releasing implant prevents pregnancy through multiple methods: by preventing ovulation, which means that no eggs are released for fertilization; by thickening the mucus of the cervix, which prevents sperm from entering; and by thinning the lining of the uterus, which makes implantation of an embryo less likely.

Implantation bleeding occurs between 7 and 14 days after fertilization, [56] and is a small amount of light vaginal bleeding or spotting that can occur in early pregnancy due to the blastocyst penetrating the lining of the uterus during implantation.
Most ectopic pregnancies (90%) occur in the fallopian tube, which are known as tubal pregnancies, [2] but implantation can also occur on the cervix, ovaries, caesarean scar, or within the abdomen. [1] Detection of ectopic pregnancy is typically by blood tests for human chorionic gonadotropin (hCG) and ultrasound. [1]
Intact VA conduction may not be apparent at the time of pacemaker implantation or even may develop at any time after implantation. [ 2 ] [ 5 ] [ 10 ] [ 11 ] Patients with noncompliant ventricles and diastolic dysfunction are particularly sensitive to loss of atrial contribution to ventricular filling and have a greater chance of developing the ...
In humans, decidualization occurs after ovulation during the menstrual cycle. After implantation of the embryo, the decidua further develops to mediate the process of placentation. In the event no embryo is implanted, the decidualized endometrial lining is shed or, as is the case with species that follow the estrous cycle, absorbed. [1]
Advanced maternal age is associated with adverse outcomes in the perinatal period, which may be caused by detrimental effects on decidual and placental development. [17] The risk of the mother dying before the child becomes an adult increases by more advanced maternal age, such as can be demonstrated by the following data from France in 2007: [18]
