#embryology

To clarify, this is an extra study for an embryology test. I am studying at uni to become a veterinary, so though I will mostly base this on a human pregnancy, I will also use some more animal elements whenever it's fit.

Second, due to not knowing the translations to some of the terms I'll be using, I will write this is portuguese and then translate this to english, so warn me if you see any mistakes in the spelling or phrasing.

Third, this is an study, it might have mistakes. I will post in my blog how I went in the test later but it was already warned that the correction will take a while, pray for me till then.

No more delays, let's start this.

Location:

First, we need to define the uterus's position in his body. Located in the pelvic cavity, in the lower abdomen, behind the bladder and in front of the rectum, is the uterus. In the male body, the prostate is in the same place. Considering the role reversal in reproduction that is already occurring in this scenario, it's easy to get rid of the prostate.

We're not counting his bisection here, but out of curiosity and considering the height at which it occurred, his uterus would be cut almost in half, in a way similar to a partial hysterectomy.

Time:

So, how long would this pregnancy last? Now this is a more complex question, because Zabraks have considerably humanoid bodies internally, with the exception of one specific part: the two hearts, which also means two cardiovascular systems.

Despite direct confirmation that all the nightbrothers have two hearts, the same is not true for the sisters. In some versions, this is something only male, or also possible in females but less frequent. Let's consider that a Nightsister pregnancy usually lasts the normal number of months due to the lack of a second heart, and then Nightbrothers' pregnancies can last longer. Let's say 10 to 12 months.

First trimester:

Let's start with the first hormone to increase, HCG (Human Chorionic Gonadotropin). It is responsible for keeping the corpus luteum producing progesterone and is what causes nausea and olfactory sensitivity. Considering that Nightbrothers are natural hunters and carry several animal characteristics, the increased olfactory sensitivity would probably be a more worrying discomfort for Maul than nausea, as it could cause an overload of senses combined with the Force. If we take into account his apprenticeship period, before TPM, he would need a rapid change in diet to be able to sustain the embryo, with emphasis on doing this before the ninth week when HCG is high.

Then there is progesterone. It relaxes the uterine muscle fibers, preventing contractions and premature labor, as well as preparing the endometrium for the embryo. But because it causes relaxation of blood vessels, it can cause drowsiness, mood swings, forgetfulness, and drops in blood pressure. For someone constantly active like Maul, this would be one of the worst hormones.

There is estrogen, which stimulates uterine growth and increases vascularization. It contributes to breast tenderness and skin changes. Inconvenient, but still not as bad as progesterone.

There is HPL (Placental Lactogen Hormone), which helps regulate metabolism and ensure the supply of nutrients to the baby. This is a hormone that can cause problems because of the dangers that excessive glucose during pregnancy can cause, risking gestational diabetes.

Second trimester:

Many reports indicate a stabilization of emotions and an increase in energy during this phase. HCG decreases, reducing nausea, and relaxin, the hormone responsible for increasing flexibility in the pelvis and joints, increases. This can cause back and pelvic pain.

Diabetogenic hormones increase, leading to insulin resistance to ensure glucose for the baby.

Some common symptoms of the second trimester are: Skin changes, as estrogen and progesterone can increase melanin, causing melasma and the linea nigra on the abdomen. Breast enlargement in preparation for milk production. Constipation/Heartburn due to progesterone relaxing the muscles of the gastrointestinal tract, slowing digestion.

Third trimester:

Estrogen is at its peak level, progesterone remains stable but begins to decrease towards the end to allow for contractions. In addition, there is: Oxytocin, which increases significantly, being the main hormone responsible for stimulating uterine contractions during labor. Relaxin, which prepares for childbirth by relaxing ligaments and pelvic joints. Prolactin increases to prepare the breasts for milk production (lactation), with possible colostrum leakage, and cortisol levels also increase, potentially causing greater fluid retention, stretch marks, and mood swings.

Some common symptoms: Braxton-Hicks contractions, which are irregular, painless practice contractions. Emotional instability, such as excitement and anxiety due to hormonal fluctuations. Heartburn and reflux, due to relaxation of the esophageal sphincter by progesterone, and insomnia, difficulty sleeping due to the size of the belly and hormones.

Labor and Delivery:

The main hormones involved in labor are oxytocin (contractions), prostaglandins (cervical ripening), endorphins (natural analgesia), adrenaline/noradrenaline (energy and expulsion), and progesterone/estrogen (regulation of onset). They work together to dilate the cervix, stimulate contractions, and manage pain, facilitating birth.

Oxytocin, also known as the "love hormone," is primarily responsible for stimulating rhythmic and strong uterine contractions during labor, as well as promoting mother-baby bonding. Endorphins (beta-endorphins), natural analgesic hormones released in response to the pain of contractions, generating a feeling of euphoria and relaxation, can be confused with adrenaline and noradrenaline; "fight or flight" hormones. A peak at the end of labor provides a sudden increase in energy for the mother and expulsive contractions.

Postpartum:

After childbirth, there is a drastic and rapid drop in estrogen and progesterone hormones, while prolactin and oxytocin increase for breastfeeding and bonding. This transition causes mood swings ("baby blues") and fatigue. Complete hormonal regulation can take months, especially in those who breastfeed. In general, hormones begin to stabilize between 3 and 6 months after delivery.

•So this is my first post (feeling little weird lol) but I wanted to share a playlist that I made! It’s about the Karl Heisenberg fanfic “Embryology” by Cantique

I added some songs based on the lyrics and some(mostly) based to Heisenberg that I think are related

Also I’d like to add (because I feel proud and happy lol) that the picture in it is made by me!!! I tried to make it like a visual board (??) or something like that yk
