Your Day-by-Day Embryo Development
The day of your egg retrieval.
No updates on these days. Embryo is left in incubator, undisturbed.
Day 2 – Day 3 – Day 4
On day 2, the embryos should start showing 2-4 cells, followed by 6-8 cells on day 3, and more than 10 cells, Morula or Compaction of the cells on day 4. During these days, the Embryology Team does not check your embryo culture to avoid disturbing the culture. Therefore, you will not receive any updates.
Day 5 – Day 6 – Day 7
The embryo can potentially reach the blastocyst stage between day 5 to day 7.
You will receive updates from our IVF Lab Team each one of these days.
Oocyte – Egg
Female gamete cells provided by the ovary.
Reproductive cell produced by males.
Mature egg. These oocytes are ready to perform ICSI or Vitrification.
Terminology used to describe that the egg is showing normal fertilization.
Early stage of embryonic development, characterized by a hollow ball of cells with an inner cell mass that will give rise to the embryo.
Blastocyst Biopsy or TE Biopsy
TE biopsy refers to trophectoderm biopsy, a procedure where a small number of cells are removed from the outer layer of the developing blastocyst for genetic analysis. The IVF Lab Team will perform the biopsy and then cryopreserve the blastocyst.
PGT-A can give information about the chromosomal genetic health of your embryo to help the care team to select an embryo for transfer, helping to improve your chances of achieving a successful pregnancy.
Chromosomes are structures made of protein and DNA that carry genetic information from the sperm and egg to the embryo. A chromosomally normal, or euploid, embryo contains 23 pairs of chromosomes amounting to 46 in total. One pair of chromosomes comes from the egg and the other the sperm. When an embryo doesn’t have the correct number of chromosomes it is called aneuploid. A euploid embryo is much more likely to result in successful implantation and the birth of a baby.
PGT-SR is appropriate for people who have a chromosome rearrangement, and thus are at risk of creating embryos with the incorrect chromosome number or structure. You may consider PGT-SR for chromosome rearrangements if you had a child or pregnancy with a chromosome rearrangement or if you or your partner are a carrier of an:
- Reciprocal translocation
- Robertsonian translocation
For people who know they are at increased risk of passing on a specific genetic condition, PGT-M, can be performed prior to embryo transfer to greatly reduce the risk of having a child affected with that condition.
PGT-M tests are created uniquely for each family. It can be performed for nearly any single gene disorder as long as the specific familial mutation has been identified and appropriate family members are available for test preparation.

Why Consult a Reproductive Endocrinology Specialist?
Reproductive endocrinologists offer a comprehensive range of fertility care services, treatments, and diagnostic procedures. These include:
Fertility Evaluations: Thorough assessments of an individual or couple’s reproductive health to identify underlying issues affecting fertility.
Ovulation Induction: Stimulating the ovaries to produce multiple eggs, enhancing the chances of fertilization through medications like clomiphene citrate.
Intrauterine Insemination (IUI): Deposition of sperm directly into the uterus during ovulation to increase the likelihood of fertilization.
In Vitro Fertilization (IVF): Retrieval of eggs from the ovaries, fertilization outside the body, and transferring resulting embryos into the uterus.
Preimplantation Genetic Testing (PGT): Screening embryos for genetic and chromosomal abnormalities before implantation.
Fertility Preservation: Cryopreservation and freezing of genetic materials, including eggs, sperm, and embryos.
Oncofertility: Fertility preservation for individuals facing cancer treatments (e.g., chemotherapy, radiation) that may impact their reproductive capabilities.
Third-Party Reproduction: Fertility care involving donated genetic materials (eggs, sperm, or embryos) or gestational surrogacy.
LGBTQ+ Family Building: Specialized services to assist LGBTQ+ individuals and couples in building their families.
Fertility Evaluation Procedures: Reproductive endocrinologists possess the expertise to conduct comprehensive evaluations aimed at identifying the root causes of infertility in individuals and couples. Common diagnostic procedures include:
Hormonal Testing: Assessing levels of reproductive hormones like follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and testosterone.
Ovarian Reserve Testing: Evaluating the quantity of a person’s eggs through blood and ultrasound imaging tests.
Hysterosalpingography (HSG): An imaging test to assess the fallopian tubes and uterine cavity for abnormalities or blockages.
Laparoscopy: A minimally invasive surgical procedure to examine the pelvic organs for abnormalities or endometriosis.
Our Reproductive Endocrinologists:
Reproductive endocrinology specialists play a pivotal role in helping individuals and couples overcome reproductive challenges while optimizing fertility to achieve their family planning goals. It’s essential to note that specific services, treatments, and subspecialties may vary among different fertility clinics and individual practitioners.
If you’re ready to take the next step on your fertility journey, we encourage you to reach out to Main Line Fertility and schedule a consultation with one of our esteemed reproductive endocrinologists.

How do I know if I have endometriosis?
The symptoms of cyclic pain may suggest endometriosis, but they are not specific to the condition, as many women experience pain during their menstrual cycle. An ultrasound can identify large ovarian cysts known as endometriomas, indicative of advanced disease, but it cannot detect early stages of endometriosis. The only definitive way to diagnose endometriosis is through laparoscopy, a surgical procedure where the surgeon visualizes and treats the disease.
