What are the success chances when transferring a grade 2 embryo? I've got three of these, each being a grade 2 on day 3. Could you also explain how the grading works and what my chances of conceiving might be?

The success chances of a grade 2 embryo transfer are relatively good, considering day 3 embryo grades are categorized into four quality levels.

Grade 1 (poor quality): More than 25% fragmentation

Grade 2 (fair quality): 10-25% fragmentation

Grade 3 (good quality): 1-10% fragmentation

Grade 4 (excellent quality): Less than 1% fragmentation

Studies have shown that embryos across all grades can lead to healthy births, but higher-quality embryos have better success rates. For day 3 embryos, the success rates are generally lower compared to blastocyst-stage embryos.

To give you a better idea, here are some general success rates for embryo transfers based on the embryo's quality and stage of development :

Excellent-grade blastocysts: 65% pregnancy rate and 50% live birth rate

Good-grade blastocysts: 59.3% pregnancy rate and 49.7% live birth rate

Average-grade blastocysts: 50.3% pregnancy rate and 42.3% live birth rate

Poor-grade blastocysts: 33.3% pregnancy rate and 25% live birth rate

Keep in mind that these are general estimates and actual success rates can vary depending on individual circumstances and the specific fertility clinic.

Given that you have three grade 2 embryos, your chances of conceiving are still relatively good, but it's essential to consult with your fertility specialist to discuss the best course of action and determine the most suitable embryo transfer strategy for your specific situation.

I've been taking metformin, and now I'm noticing these skin rashes that seem like an allergic reaction. Is there another medication I could try instead of metformin?

If you are experiencing allergic reactions to metformin, an alternative medication that can be considered is "Glipizide". The usual starting dose of Glipizide is 5 mg taken orally once daily.

I'm curious about whether it's okay for someone with a hypothyroid condition to drink Ragi malt or Ragi Java. Could consuming ragi millets have any adverse effects on hypothyroidism?

Ragi malt or Ragi Java can be safely consumed by most people with hypothyroidism, but like any food, its best to eat it in moderation. If you consume ragi or other millets frequently, it may be a good idea to monitor your thyroid levels regularly with your doctor and ensure youre getting enough iodine. Ensure a well-balanced diet, and consider reducing your intake of other goitrogenic foods if you are concerned about the impact on your thyroid.
