The cervix acts as a door between the vagina and the uterus. It opens and thins during ovulation to allow sperm to enter the uterus and potentially fertilize an egg.
ovulation normally occurs about 2 weeks before your period actually starts. The purpose of a period is a direct relation to the release of an egg during ovulation. The egg will be released from the falopian tubes and enter the uterus (ovulation). Once the egg sits in the uterus for several days if it is not penetrated by sperm the body will reject it by causing contractions of the uterus to release the egg. This is when your period occurs as your uterus is "washing" out the egg from the uterus. So....yes...ovulation always occurs before your period.
Sperm can live inside the female reproductive tract for up to five days. After ejaculation, they can survive and remain viable in the uterus and fallopian tubes, ready to fertilize an egg if ovulation occurs during that time.
A complex interaction between the pituitary gland in the brain, the ovaries and the uterus work to create the perfect environment for ovulation (the release of an egg) to occur, for the sperm and egg to meet and for the fertilised egg to implant itself in the uterus.
The journey of the oocyte through the uterine tubes to the uterus following ovulation normally takes about 3-4 days. During this time, the oocyte may encounter sperm for fertilization in the fallopian tube before reaching the uterus for possible implantation.
The entry of the uterus is called the cervix. It is the narrow, lower part of the uterus that connects to the vagina. The cervix allows menstrual blood to flow out of the uterus during menstruation and also serves as the passageway for sperm to enter the uterus during intercourse.
intrauterine insemination
If an egg does not get fertilized by a sperm within 24 hours after ovulation, it will disintegrate and be absorbed by the body. The unfertilized egg, along with the lining of the uterus, will be shed during menstruation.
The mature egg is released from the ovary during ovulation and travels through the fallopian tube towards the uterus. If the egg is fertilized by sperm along the way, it may implant in the uterus and develop into a pregnancy. If not fertilized, the egg will disintegrate and be shed during menstruation.
Once a follicle releases an egg (ovulation), the egg will travel down the fallopian tube towards the uterus. If fertilized by a sperm during this journey, it may implant in the uterus and develop into a pregnancy. If not fertilized, the egg will disintegrate and be shed during menstruation.
CM during ovulation only lasts three days and looks like egg-whites. CM caused by being pregnant increases in quantity and looks like a mixture of ovulation discharge and natural vaginal discharge. Just lots more of it.
the sperm reaches the uterus through the cervical opening or cervical os.
