Stages of pregnancy

Weeks 1-3:
The female hormone oestrogen will trigger a women’s uterus so it forms a thick blood-rich lining of tissue. The other female hormone progesterone will begin to prepare the uterus so it can support a fertilised egg and accommodate the growing baby over the next few months. During this time, the woman’s ovaries will also ripen the eggs in follicles (sacs filled with fluid).

Ovulation
This is a part of the menstrual cycle where the woman’s ovaries release an ovum (egg). The ovum will then travels down the fallopian tube. The ovum is usually released on the 14th day before the woman’s period.
Conception
When a man and woman have sexual intercourse around the time of ovulation, the sperm produced and released by the man will travel to meet the ovum. The sperm will then pene-trate the egg. Once the ovum is penetrated it hardens and becomes impermeable so no other sperm can enter.

Implantation

The first stage con-sists of early labour, active labour and the transitional phase. In order for the baby to be born, the cervix needs to ripen and open. Whilst this is happening, the woman may experi-ence moderate and regular contractions, backaches or stomach aches. This phase is also known as pre-labour. As a result of these changes, the mucus plug in the cervix can come out. This is called a show. By the end of this stage, the woman’s cervix will be fully dilated and open to about 10 cm in diameter.
During early labour, the cervix starts to open and widen. Some people may experience gen-tle contractions at first so they may not notice it starting. This may feel like light menstrual cramps or a tedious ache or backache. However, some people notice progressively agoniz-ing and painful contractions. Early labour can be unpredictable. For some women, it may carry on at the same pace. For others, it may stop and start. For others, it can smoothly lead into active

    1) What is the question the authors are trying to answer? - The authors are trying to determine if progesterone would make a difference on the quality of the embryos during the growing stage of the first follicular wave. 2) What is the hypothesis of the study? - The hypothesis of this study is that if a person were to induce a cow to ovulate follicles during the first follicular wave, that would minimize the embryo quality due to progesterone concentration at the time of growing the follicle and would also increase the pulsation of LH. It would also premature oocyte development.…

    Human genetics have led the way into new techniques of conception as well as embryo growth. Gene therapy has allowed genetic specialists to experiment with embryos in order to attempt to heal congenital birth defects as well as hereditary disorders. Although, the embryo receives nutrients from outside sources, the fetus receives no nutrition from the umbilical cord of a mother ultimately reducing the chances of survival. People who favor the use of human genetics for conception suggest that the technologies increase the chance of infertile parents creating offspring. However, the truth is using human genetics for conception increases the chance of a miscarriage, while also putting the mother and child in danger.…

The plug can come out as a hard and bloody plug, or it can come out as a smear of mucus over a few days. Every woman is different and there isn’t a right or wrong way for the mucus plug to…

    The 28 day menstrual cycle is the timing of the changes that occurs within a woman's body, and is described as the interplay of hormones from the ovaries and the anterior pituitary. The anterior pituitary secretes FSH (follicle-stimulating hormone) and LH (luteinising hormone). When FSH secretion increases is counted as day one, and the initial day of menstruation. Due to FSH the Ovum begins to enlarge within the ovary, as well as increasing the follicle cells. The FSH causes these cells to secret oestrogen into the blood.…

    1.1 Describe stages of development from conception to birth. When an egg is fertilised it is a single cell called a Zygote, in the next 24-36 hours the single cell will divide into two cells, 12 hours after it will divide into four cells, and will carry on dividing which forms a cluster of cells which are called a monula. Three – four days after it has been fertilised the monula will move from the fallopian tube and will enter the uterus. At about six days the monula will form a hollow cavity which is known as a blastocyst. The blastocyst will burrow itself into the uterus lining this is called implantation.…

    The phase is what leads to the formation of the corpus luteum, it starts on the 15th day and ends with the menstrual cycle–the 28th day. It is important to know that usually, in this phase eggs burst from their follicle making the follicle to rupture but the follicle stays on the surface of the ovary anyway. After two weeks the ruptured follicle would have completely transformed to a "Corpus Luteum. " The Corpus Luteum then begins to release progesterone and estrogen in high and low quantities respectively. This duo work together to maintain the endometrium–"the thickened lining of the uterus, a preparation for…
