The chemistry of pregnancy and progesterone
Pregnancy is the development and fertilization of offspring. The name of the offspring that is growing in a women’s uterus is known as an embryo or fetus. Delivery of child usually happens, about 38 weeks after conception. This is roughly 40 weeks from the start of the last normal menstrual period. Conception can be attained by sexual intercourse or with a form of assisted reproductive technology.
Progesterone is a natural female hormone. Progesterone is one of the keys to conceiving. Any woman who wishes to become pregnant needs progesterone to support the uterus and help maintain a fertilized egg. Progesterone, is called the hormone of pregnancy and it has many roles linking to the development of the fetus. Progesterone can relax smooth muscles and even the womb in the body. Progesterone can also lead to some relaxing of the blood vessels through the body. It can promote lower than normal blood pressure. Progesterone can occasionally cause dizziness and vertigo. Progesterone can increase hair growth on your lower abdomen or breast.
Progesterone is created early in pregnancy by, corpus luteum, a cyst on the ovary. The corpus luteum endures the production of progesterone until about 10 weeks in the pregnancy. After about 10 weeks into the pregnancy is when the placenta takes over production. The first trimester is when, levels of progesterone rise greatly. Progesterone does some very crucial jobs along the way. The progesterone helps keep the uterus muscle relaxed. The progesterone plays a role in the immune system. This hormone, progesterone, helps the body bear foreign DNA. The fetus is considered foreign DNA.

The placenta will take over production from the ovaries. When the placenta takes over it will significantly increase production of progesterone.
In conclusion, the entire pregnancy from start to finish is based entirely on hormones. Hormones are considered to be a chemical release through one or more cells that affect cells in another part of the organism. There are many hormones that make it possible for a child to be conceived. Progesterone, Human Chorionic Gonadotropin, estrogen, oxytocin, prolactin, and relaxin all is what helped each and every person on earth be conceived. Pregnancy is only possible because of the hormones in a female body. Pregnancy is the only reason we are here today.

The length of a normal and healthy pregnancy is 38 weeks since conception. During the 38 weeks (9 months) the baby is developing in stages in the utero. The 38 weeks are divided into three periods of development, the period of the zygote, the period of the embryo, and the period of the fetus. The period of the fetus begins during the ninth week and is fully developed by 38 weeks. Weight gain slowly occurs at the start of the fetus period, and
This is a topic that is seemingly impossible reach a compromise on. Initially, it would make sense to understand the cognitive processes of a fetus at the various stages of development. There is reasonable evidence that the fetus does not have sustainable mental activity until 23 weeks after conception (Gazzaniga, 2005, p.8). The argument could be made, based on the neural activity of the fetus, that abortion is not morally ethical after the 23rd week following conception. Despite this scientific evidence, there is still a lack of agreement among persons debating this issue. For example, approximately 89 percent of abortions take place before the 12th week after conception (Hinman, 2014, p.11), yet many people view conception as the beginning of life and will therefore not support abortion, even if it happens before the fetus has sustainable mental activity. Understandably, the solution is once again not easily agreed upon. One must consider the social implications of abortion, or lack there of prior to deeming it acceptable or not. For example, women who are victims of rape and incest should have no obligation to carry out a pregnancy, regardless of point in time after conception. "An abortion can avoid disgrace to an unwed mother." (Mahamood, 2015, p.69) The answer to the morality of abortion lies deeper than understanding the
Conception is the action of conceiving a child or of a child being conceived. Every human being begins life as a single cell, formed when father's sperm fertilizes mother's egg. Fertilization normally takes place in the mother's Fallopian tube, which connects the uterus (womb) with the ovary. The uterus is the size and shape of a large pear: it is made of muscle and it stretches to allow the baby's growth throughout the months of pregnancy.
pregnancy, up to 49 days after conception, the woman has two choices. The first is to
Childbirth is nothing short of a miracle. The placenta—the organ connecting a developing fetus to the uterine wall and allowing for waste elimination, nutrient uptake and gas exchange via the mother's blood supply—filters most harmful substances that threaten an embryo, though some may still pass on to the fetus. These harmful substances, called “teratogens,” range from environmental chemicals to the passing of maternal diseases, and can negatively impact the normal developmental cycle of a fetus. The title “teratogen,” however, effectually refers to any substance or chemical exposure with the potential to cause birth defects in prenatal development. Exposure to teratogens can result in a broad spectrum of physiological and psychological issues in later life, including malformations of the body. (Malformations resulting from exposure to one of the most common teratogens—alcohol—can be observed notoriously in Fetal Alcohol Syndrome, or FAS, where patterns of mental and physical defects develop in association with high levels of alcohol consumption during pregnancy.) Though the toxicity of these teratogens is particularly damaging during the fourth through tenth weeks of gestation, teratogens can harm throughout the span of development in the womb.
Each second of fetal development during pregnancy is of extreme importance. This period of prenatal development is a time of change and growth with many factors affecting all areas of growth. Different stimuli having long-lasting effects on development is a process known as programming. The goal of this first article, (put the name of the article here) is to look into the idea of programming and how the influence of stress effects prenatal development. It begins with a biological approach. Looking at the role of Glucocorticoids cortisol in fetal development, the article states that they play a critical role in development and are associated with the “hypothalamic-pituitary-adrenal (HPA) axis, one of the body’s major stress responsive systems.” (Davis & Sandman, 2010) This cortisol increases in mothers over the course of pregnancy and is important in brain development in the fetus. While these Glucocorticoids are important and essential to prenatal development, overexposure can lead to negative effects, including emotional disturbances in early childhood, deregulated stress responses in infa...
First, the pituitary gland in the brain produces the hormone follicle stimulating hormone (FSH). FSH stimulates the ovaries to produce estrogen, which thickens the uterine lining and begins to develop an egg in the ovary. About 14 days later, the pituitary gland produces another hormone called luteinizing hormone (LH). LH causes the egg to come out of a sac in the ovary (ovulation). The empty sac on the ovary called the corpus luteum is stimulated by another hormone from the pituitary gland called luteotropin. The corpus luteum begins to produce the estrogen and progesterone hormone. The progesterone hormone prepares the lining of the uterus to have the fertilized egg (egg combined with sperm) attach to the lining of the uterus and begin to develop into a fetus. If the egg is not fertilized, the corpus luteum stops producing estrogen and progesterone, it disappears, the lining of the uterus sloughs off and a menstrual period begins. Then the menstrual cycle starts all over again and will continue monthly unless pregnancy occurs or menopause
It isn’t just your body anymore, once you 're pregnant there 's a defenseless baby inside of you that only you can protect. You can give your child a happy life and help a couple that can’t physically reproduce have a baby.

During menopause and in the perimenopausal years, the estrogen levels gradually decrease and the ovaries put out less progesterone. This results in a rise in FSH and LH, which can
From the moment of conception the baby begins to develop for the remaining nine months. A full term pregnancy can take 38 weeks-40 weeks or nine months based on either date of conception or the last day of the woman’s menstrual cycles. If mom does not know the date of conception, than doctors will add 40 weeks to the last day of her last menstruation and estimate the baby’s due date accordingly.
It takes at least 20 weeks for a child to fully develop inside the womb starting the day of conception. A full pregnancy lasts 42 weeks. During the first week
Every woman when pregnant has a 3-5% chance of having a baby born with a birth defect, and these chances increase when the developing fetus/ embryos are exposed to teratogens, whether it’s intentional or unintentional (Bethesda (MD), 2006). Teratogens can cause severe birth defects, malformations, or terminate the pregnancy altogether (Jancárková, & Gregor, 2000). The placenta is known as an effective barrier from any detrimental pathogen that can potentially hurt the fetus. The timing of exposure of any teratogen is critical to the impact of prenatal development (Bethesda (MD), 2006). The most vulnerable time of the fetus for severe damage is during early pregnancy when all the major organ and central nervous system (CNS) are developing. Miscarriages have an important role in keeping a pregnancy from evolving when there is something serious going on with the developing fetus/embryo. Miscarriages are more common than we think and are the most familiar type of pregnancy loss (Bethesda (MD), 2006).
“ Being a Motherhood is a choice you make every day, to put someone else's happiness and well-being ahead of your own, to teach the hard lessons, to do the right thing even when you're not sure what the right thing is...and to forgive yourself, over and over again, for doing everything wrong.” MMMMM. Being mother is one of the most blessed and the most challenging job in the world. Giving birth to a new life and making it walk through the new world holding its hands showing a good trail makes a mother victorious in her life. In this modern world women’s attitude against pregnancy and being a mother is changing accordingly. There occurs so many miscarriages and maternal death during the pregnancy. A woman should be physically, and more over mentally set to have a baby in her womb. Considering the biological fitness of health it’s said that safer age to be get pregnant is in between 20 to 29. Early pregnancy in the teenage age of 13 to 20 and the delayed motherhood age after 35 is challenging to the health of mother as well as the birth of the child causing currently social issues India.
