How does Pregnancy Happen?
Source 2: Planned Parenthood
How does pregnancy happen?
In order for pregnancy to happen, sperm needs to meet up with an egg. Pregnancy officially starts when a fertilized egg implants in the lining of the uterus. It takes up to 2-3 weeks after sex for pregnancy to happen.
How do people get pregnant?
Pregnancy is actually a pretty complicated process that has several steps. It all starts with sperm cells and an egg.
Sperm are microscopic cells that are made in testicles. Sperm mixes with other fluids to make semen (cum), which comes out of the penis during ejaculation. Millions and millions of sperm come out every time someone ejaculate — but it only takes 1 sperm cell to meet with an egg for pregnancy to happen.
Eggs live in ovaries, and the hormones that control someone's menstrual cycle cause a few eggs to mature every month. When the egg is mature, it means it’s ready to be fertilized by a sperm cell. These hormones also make the lining of someone's uterus thick and spongy, which gets someone's body ready for pregnancy.
About halfway through someone's menstrual cycle, one mature egg leaves the ovary — called ovulation — and travels through the fallopian tube towards someone's uterus.
The egg hangs out for about 12-24 hours, slowly moving through the fallopian tube, to see if any sperm are around.
If semen gets in someone's vagina, sperm cells can swim up through the cervix. The sperm and uterus work together to move the sperm towards the fallopian tubes. If an egg is moving through the fallopian tubes at the same time, the sperm and egg can join together. The sperm has up to six days to join with an egg before it dies.
When a sperm cell joins with an egg, it’s called fertilization. Fertilization doesn’t happen right away. Since sperm can hang out in someone's uterus and fallopian tube for up to 6 days after sex, there’s up to 6 days between sex and fertilization.
If a sperm cell does join up with the egg, the fertilized egg moves down the fallopian tube toward the uterus. It begins to divide into more and more cells, forming a ball as it grows. The ball of cells (called a blastocyst) gets to the uterus about 3–4 days after fertilization.
The ball of cells floats in the uterus for another 2–3 days. If the ball of cells attaches to the lining of the uterus, it’s called implantation — when pregnancy officially begins.
Implantation usually starts about 6 days after fertilization, and takes about 3-4 days to complete. The embryo develops from cells on the inside of the ball. The placenta develops from the cells on the outside of the ball.
When a fertilized egg implants in the uterus, it releases pregnancy hormones that prevent the lining of someone's uterus from shedding — that’s why people don’t get periods when they’re pregnant. If someone's egg doesn’t meet up with sperm, or a fertilized egg doesn’t implant in someone's uterus, the thick lining of someone's uterus isn’t needed and it leaves someone's body during someone's period. Up to half of all fertilized eggs naturally don’t implant in the uterus — they pass out of someone's body during someone's period.
What are early pregnancy symptoms?
Many people notice symptoms early in their pregnancy, but others may not have any symptoms at all.
Common signs and symptoms of pregnancy can include:
Missed period
Swollen or tender breasts
Nausea and/or vomiting
Feeling tired
Bloating
Constipation
Peeing more often than usual
Some early pregnancy symptoms can sometimes feel like other common conditions (like PMS). So the only way to know for sure if you’re pregnant is to take a pregnancy test. You can either take a home pregnancy test (the kind you buy at the drug or grocery store), or get a pregnancy test at the doctor’s office or local Planned Parenthood Health Center.
Contemporary Categories of Contraception
Today, we have two main methods for stopping a pregnancy from occurring. These are:
Hormonal
Hormonal methods work by changing the naturally occurring hormones in the female body, generally progestin and/or estrogen, to either stop ovulation or implantation or to thicken the cervical mucus so that sperm cannot get through.
Examples include: the Implant, the Pill, the IUD, etc…
Barrier
Barrier methods are exactly what they sound like, they physically stop the sperm from entering the uterus so that fertilization cannot occur.
Examples include: the internal condom, the external condom, the diaphragm…
Three Biblical Categories of Contraception
I. Onanism
Source 3: Genesis 38:8-10
Then Judah said to Onan, “Join with your brother’s wife and do your duty by her as a brother-in-law, and provide offspring for your brother.”
But Onan, knowing that the offspring would not count as his, let [the semen] go to waste whenever he joined with his brother’s wife, so as not to provide offspring for his brother.
What he did was displeasing to HaShem, who took his life also.
וַיֹּ֤אמֶר יְהוּדָה֙ לְאוֹנָ֔ן בֹּ֛א אֶל־אֵ֥שֶׁת אָחִ֖יךָ וְיַבֵּ֣ם אֹתָ֑הּ וְהָקֵ֥ם זֶ֖רַע לְאָחִֽיךָ:
וַיֵּ֣דַע אוֹנָ֔ן כִּ֛י לֹּ֥א ל֖וֹ יִהְיֶ֣ה הַזָּ֑רַע וְהָיָ֞ה אִם־בָּ֨א אֶל־אֵ֤שֶׁת אָחִיו֙ וְשִׁחֵ֣ת אַ֔רְצָה לְבִלְתִּ֥י נְתׇן־זֶ֖רַע לְאָחִֽיו:
וַיֵּ֛רַע בְּעֵינֵ֥י HaShem אֲשֶׁ֣ר עָשָׂ֑ה וַיָּ֖מֶת גַּם־אֹתֽוֹ׃
II. "Cup of Roots"
Source 4: Yevamot 65B:3, 17
A man is commanded with regard to the mitzva to be fruitful and multiply, but not a woman. Rabbi Yoḥanan ben Beroka says that a woman is also commanded, as the verse states with regard to both of them: “And G!d blessed them, and G!d said to them: Be fruitful and multiply” (Genesis 1:28).
She said: Is a woman commanded to be fruitful and multiply? He said to her: No. She went and drank an infertility potion.
הָאִישׁ מְצֻוֶּוה עַל פְּרִיָּה וּרְבִיָּה אֲבָל לֹא הָאִשָּׁה רַבִּי יוֹחָנָן בֶּן בְּרוֹקָה אוֹמֵר עַל שְׁנֵיהֶם הוּא אוֹמֵר וַיְבָרֶךְ אוֹתָם אֱלֹהִים וַיֹּאמֶר לָהֶם [אֱלֹהִים] פְּרוּ וּרְבוּ
אֲמַרָה אִתְּתָא מְפַקְּדָא אַפְּרִיָּה וּרְבִיָּה אֲמַר לַהּ לָא אֲזַלָא אִשְׁתְּיָא סַמָּא דַעֲקַרְתָּא
Source 5: Shulchan Arukh, Even HaEzer 5:12
A person who gives a cup of root drink to a person or any living thing in order to render him impotent, this is forbidden. But, he (the giver of the drink) is not lashed. However, for a woman it is permitted to drink this root drink in order that she becomes impotent so she cannot give birth.
המשקה כוס של עיקרין לאדם או לשאר בעלי חיים כדי לסרסו ה"ז אסור ואין לוקין עליו ואשה מותרת לשתות עיקרין כדי לסרסה עד שלא תלד:
Source 6: Peninei Halakhah, Simchat Habayit U'Virkhato 5:19 (by Eliezer Melamed in the 2010s)
However, it is permissible to prevent pregnancy indirectly, by means of two main methods: a) taking birth control pills; b) inserting an IUD (intrauterine device). These are considered the most effective contraceptive methods and the most halachically preferred, because the prevention of pregnancy takes place in the body of the woman, and indirectly, with no harm done to the sperm. Therefore, when birth control is permitted, these methods are permissible according to all opinions.
III. Mokh
Source 7: Niddah 45A:12
The baraita [an older piece of text] specifies the reason for allowing these women to use the Mokh: A minor, lest she become pregnant and perhaps die from this pregnancy; a pregnant woman, lest she be impregnated a second time and her older fetus become deformed into the shape of a sandal fish, by being squashed by the pressure of the second fetus; and a nursing woman, lest she become pregnant and her milk dry up, in which case she weans her son too early, thereby endangering him, and he dies.
קטנה שמא תתעבר ותמות מעוברת שמא תעשה עוברה סנדל מניקה שמא תגמול את בנה וימות
Source 8: Peninei Halakhah, Simchat Habayit U'Virkhato 5:19 (by Eliezer Melamed in the 2010s)
There are two contraceptive methods that are halakhically controversial. One is the use of a spermicidal foam, gel, or suppository that a woman inserts into her vagina before sexual relations. The second is the use of a diaphragm, a shallow, dome-shaped cup that a woman inserts in the vagina to block the opening of the cervix to block sperm from reaching the uterus. Spermicide is usually placed on the diaphragm in order to increase the effectiveness of the contraceptive.
Poskim who are lenient maintain that since the woman is the one who inserts the diaphragm or spermicide, and since the couple has sexual relations without any barriers between their bodies, it is not considered a waste of seed, only a means of preventing the sperm from reaching the uterus and fertilizing the ovum. Those who are stringent maintain that using spermicide is, by definition, destroying seed.
When there is a real need to avoid pregnancy, and for whatever reason birth control pills and an IUD are contraindicated, a couple may use these two methods. However, if spermicides and diaphragms were more effective, it would be permissible to rely on the lenient views only under extenuating circumstances. It is precisely because there is more than a ten percent chance that a woman using these methods will get pregnant within a year that they may be used if necessary. This is on condition that a couple using them have reconciled themselves that should a pregnancy occur they will accept it with good grace.
