In human female, the blastocyst

forms placenta even before implantation

gets implanted into uterus three days after ovulation

gets nutrition from uterine endometrail secreation only after implantation

gets implanted in endometrium by the trophoblast cells

Solution

gets implanted in endometrium by the trophoblast cells

Implantation is the attachment of blastocyst to the uterine wall (endometrium). It occurs after 6-7 days of fertilisation. during Implantation, the trophectoderm (trophoblast) comes in contact with the endometrium of the uterus and sinks into a pit formed in the endometrium and get completely buried in the endometrium. Trophoblast cells form specialised structures called villi, which help in absorption of nutrient materials.
