And today I’m back with information for the partners / what people NOT tell you about how the egg works and what it’s actually doing once connected to sperm IF it can connect.

First before anything.
Anyone with “Normal Karyotype” post miscarriage with RPL the “why” you are asking for is likely critical placental development error from sperm genome.

Recurrent pregnancy loss (RPL) accompanied by a normal embryonic chromosomal karyotype (euploid) frequently eludes clinical explanation. While maternal age and meiotic non-disjunction drive numerical chromosomal aberrations (trisomies), structural embryonic and placental anomalies resulting in first- and second-trimester demise often origin

One of my closest friends (38) recently entered a relationship with a 44-year-old partner diagnosed with obstructive sleep apnea (OSA). He is otherwise considered “healthy.”

Because of what I’ve studied and written about for over a decade, I suggested she have him undergo a full semen analysis.

The results?

One of the most pristine semen analyses I’ve ever seen - even compared to donor samples.

• 250 million sperm/mL

• 70% motility

• 9% morphology

• Well above WHO reference ranges

• “Perfectly fertile” per urologist

Most clinics would stop there. We did not. Because sleep apnea is not a semen parameter problem. It is a hypoxia problem. She proceeded with DNA Fragmentation Index (DFI

Research indeed shows that paternal factors—including sperm quality, diet, environmental exposures, and epigenetic marks—can increase the risk of neural tube defects (NTDs) in mouse offspring. However, mainstream narratives often focus on maternal causes like folate deficiency, which can obscure paternal contributions. Here’s an overview:

⸻

  1. Paternal Genetic Variants Impact NTD Risk • A human/mouse study linked a paternal variant in the folate‐metabolizing gene MTHFD1 G1958A to significantly increased risk of anencephaly and spina bifida — pointing to fathers not just mothers in folate-related defects  .

Here’s what current research shows about how sperm contributes to placental development—and how sperm-related issues can lead to placental problems and miscarriage:

⸻

🧬 1. Paternal DNA and Imprinting Drive Placental Growth • Imprinted genes like IGF2 (paternal-expressed) are critical for placental development. Maternal genes often act to limit growth—creating a balance. Disruption can impair placental structure and function . • Classic experiments show that embryos with only paternal genomes develop placental tissues but not embryos, while those with only maternal genomes do the opposite .

Title: How to Read Your Sperm Analysis: Everything They Didn’t Say — From Someone Who Gives a Sht*

If you're here because your sperm analysis is confusing, your clinic isn’t helping, or your partner is being asked to undergo invasive testing while you’ve barely had a full workup—you’re not alone. That’s exactly why I wrote this post in the first place.

You can read the full, unaltered version of the HOW TO READ YOUR SPERM ANALYSIS guide—updated, accurate, and ethical for 2025.

WHY IS IT $1?

Because this isn’t about money. It’s about ownership.

$1 protects this work from being reposted, repackaged, or stolen again—especially by those who removed the author but kept her words.

Q&A: Social Media Inbox Series

Positive NIPT for Trisomy 15

I get a lot of questions in my DMs. Over the last year, there are thousands. Right now, there are over 2,000 unread. Believe it or not, that’s impossible to answer individually. Since this community has grown, the best way I can respond is through video and data. So when I catch a question like this one, I’ll try to break it down here and in video. And if you ever have a question like this again, the best way to reach me is to tag me on TikTok. That’s the only way I can reply directly and actually explain it. Right now, it’s too difficult to respond to notifications or messages because my inbox is completely shattered.

Good evening everyone—

I hope all of you are staying sane. If not, that's okay. You're allowed. (I WAS THERE THAT ONE DAY https://www.reddit.com/r/NIPT/comments/ezuvfh/my\_trisomy\_18\_nipt\_false\_positive\_story\_so\_far/)

Welcome & thanks for being so helpful and answering questions!

I am going through a personal issue with my partner getting a stage 4 diagnosis of his colon cancer out of no where at 38 with liver mets and our 4 kids. It’s a scary time so I’ve taken a step back for this reason to focus on his chemo and treatment. Wish us luck and I’m still around. Tagging me for a question is the best way to get a hold of me 🌺

This space is very special to me and my false positive NIPT daughter is now 5 from false positive t18. My other daughter with MOM of 8 for hcg and abnormal labs and normal amnio is also 5. My son with short 1% long bones is now 2 and perfect. So basically. Don’t trust every scan and

Can I ask a question if anyone just thinks life is fucking boring and mundane and I have no idea what I’m doing with my life anymore? My kids are 4,4 twin girls and 2 year old boy and my partner had a 4 year old girl and just got diagnosed with stage 4 cancer that’s terminal. They gave 1-5 years depends how he responds to chemo surgery etc. But I just come home, feed the kids, sometimes I’m happy to see them but sometimes it’s just so awful and I feel trapped and also feel bad. On top of the cancer thing my coparent is moving an hour away and has school designation so I have no idea what I’m going to do when my 2 year old gets older and needs to be dropped off and picked up 1/2 the time to

Looking to add a Moderator for r/NIPT

Hi everyone,

When I first started this subreddit, there was almost no information online about false-positive NIPT results and how common they can be. My own journey to parenthood was incredibly challenging—marked by male infertility, five miscarriages, a termination in the second trimester for abnormalities, five IVF cycles, 12 failed embryo transfers, and a surrogacy journey that eventually led to having my two children. Both of my kids had abnormal prenatal testing results and required amnios. It was through these deeply personal and painful experiences that I realized how common and under-discussed these issues were, especially as NIPT testin
