To achieve successful implantation, the uterus should undergo structural and functional remodeling. Estrogen and progesterone are the master hormones mediating these changes. Estrogen and progesterone bind to their respective nuclear receptors.
Implantation happens when a fertilized egg burrows into the uterine lining and begins to grow. 1 When this can occur for each person is dependent on their overall cycle length, which is not the same for everyone, and when the egg was fertilized.
Think lots of fresh fruits, vegetables, good quality proteins, nuts and seeds, healthy fats and whole grains. The key here is blood sugar control to support implantation and early embryo development, so limit the junk and focus on real, nutrient-dense food.
It's recommended that you avoid strenuous physical activities like heavy weight-lifting or high-impact cardio during your two-week wait as it could lead to uterine contractions and affect the implantation process. After the first few days of our waiting period, you can do some light exercising like walking or swimming.
Some women do notice signs and symptoms that implantation has occurred. Signs may include light bleeding, cramping, nausea, bloating, sore breasts, headaches, mood swings, and possibly a change in basal body temperature. But — and here's the frustrating part — many of these signs are very similar to PMS.
In summary, implantation occurred 8 to 10 days after ovulation in most healthy pregnancies.
Studies show implantation can occur anywhere from 6 to 12 days after ovulation. More commonly, implantation typically occurs on days 8, 9, or 10 past ovulation. By now you may be wondering, Okay, but why is implantation so important?
The best advice is common sense: eat healthily, avoid cigarette smoke, exercise gently, and try some relaxation techniques. You don't need to confine yourself to bed, but you should go easy on yourself, as you're going through a lot – both physically and emotionally.
Getting an estrogen boost may help improve the uterine lining over time. Furthermore, supplements such as iron, digestive enzymes, fish oils, and vitamin E can help. Some studies show L-Arginine, turmeric, and even low-dose aspirin can also help.
During the two-week wait, it's better to err on the side of caution. Avoid having a drink, smoking, or any other activity that could be harmful to a brand new pregnancy. It's fine to continue exercising if you already have a workout routine, but now might not be the time to take up a new, intense form of exercise.
These data strongly indicate that caffeine treatment can directly impair uterine receptivity and thus compromise embryo implantation.
There's no reason to believe masturbation can affect implantation. No research suggests it does. Masturbation also can't cause an ectopic pregnancy.
Overall, there is no research confirming that orgasming from sex or masturbation can impact embryo implantation during non-IVF conception. Orgasming doesn't impact ovulation and fertilization and is unlikely to impact implantation.
In addition, alcohol consumption, smoking and other modifiable lifestyle factors in both parents (including poor diet, exercise and being overweight) may also contribute to recurrent implantation failure by affecting egg/sperm quality and the health of the uterine environment.
In most successful implantations, the arrival of the egg coincides with peak levels of luteinizing hormone (LH), which primes the endometrium to accept the embryo. In addition to LH, a chemical called trypsin, produced by the embryo signals the uterine lining to prepare for implantation.
Science says, not exactly. In the 1900s, some experts came up with the idea of the “upsuck theory,” which essentially hypothesized that the uterine contractions that occur during an orgasm propel semen into the vaginal canal. But many studies have since proven that an orgasm is unlikely to factor into conception.
Women who usually slept supine at the time of conception and implantation were significantly more likely to have a high or fundal placental location compared with those who usually slept in the prone position (p = 0.041).
Generally, the endometrium near the fundus (static and fundal areas) is considered a more suitable location for embryo implantation.
After implantation, production of hCG starts from cells in the developing placenta (tissue that will feed the fetus). Trace levels of hCG can be detected as early as eight days after ovulation. That means you could get positive results several days before you expect your period to start.
If you take a pregnancy test before implantation occurs, the test will tell you that you're not pregnant, even if you have actually conceived. Since hCG is not yet in your system, the test cannot detect it.
Day 1 and 2: The blastocyst hatches out of its shell and begins to try to attach itself to the uterus. Day 3: Implantation begins as the blastocyst moves deeper into the uterine lining. Day 4 and 5: Implantation continues and becomes complete. The cells that will be the placenta and fetus begin to develop.
The causes of implantation failure are diverse and especially due to different maternal factors as uterine abnormalities, hormonal or metabolic disorders, infections, immunological factors, thrombophilias as well as other less common ones.
For men with normal sperm counts, studies find that semen volume and sperm count/concentration increase after two days of abstinence. However, sperm quality—the motility (movement) and morphology (shape) of sperm—decrease after two days of abstinence, with a significant impact seen after 7–10 days.
