Intralipid IV Therapy for Fertility & Immune Health
Physician-administered Intralipid infusions for patients with recurrent pregnancy loss, IVF implantation failure, and immune system dysregulation — coordinated with your fertility specialist and supervised by Dr. Jeffrey A. Weiss, MD.
A Targeted IV Therapy for Immune Modulation
Intralipid is a sterile intravenous emulsion composed of soybean oil, egg phospholipids, glycerin, and water. Originally developed as a nutritional supplement for patients requiring parenteral nutrition, it has since been studied extensively for its immunomodulatory properties — particularly in the context of reproductive medicine and immune dysregulation.
At Infusion Center of NJ, Dr. Weiss administers Intralipid infusions as part of a comprehensive, physician-supervised protocol. We work closely with reproductive endocrinologists (REIs) and fertility specialists throughout New Jersey to support patients undergoing IVF, frozen embryo transfer, and other assisted reproductive procedures.
The NK Cell & Immune Modulation Mechanism
Intralipid therapy is believed to work by modulating the activity of natural killer (NK) cells — a type of immune cell that plays a critical role in early pregnancy. In some patients, elevated or hyperactive uterine NK cells may attack embryos, preventing successful implantation or contributing to early pregnancy loss. Intralipid appears to suppress this overactive immune response, creating a more receptive environment for implantation and early fetal development.
NK Cell Suppression
Intralipid reduces the cytotoxic activity of peripheral and uterine natural killer cells, which may otherwise interfere with embryo implantation.
Th1/Th2 Immune Balance
The therapy helps shift the immune response from a pro-inflammatory Th1 profile toward a more tolerogenic Th2 profile — essential for a successful pregnancy.
Lipid-Mediated Signaling
The lipid components in Intralipid interact with immune cell membranes, modulating cytokine production and reducing inflammatory signaling pathways.
Endometrial Receptivity
By calming immune overactivation, Intralipid may improve the endometrial environment, supporting embryo attachment and early placental development.
Conditions & Indications
Intralipid infusions may be appropriate for patients with the following diagnoses or clinical histories. A consultation with Dr. Weiss is required to determine eligibility.
Fertility & Reproductive
- Recurrent pregnancy loss (RPL) — two or more consecutive miscarriages
- Recurrent IVF implantation failure (RIF)
- Elevated uterine or peripheral NK cell activity
- Unexplained infertility with immune component
- Frozen embryo transfer (FET) support
- Thin endometrial lining with immune etiology
Immune & Autoimmune
- Antiphospholipid syndrome (APS)
- Autoimmune thyroid disease (Hashimoto's, Graves')
- Systemic lupus erythematosus (SLE)
- Elevated antinuclear antibodies (ANA)
- Immune dysregulation without clear autoimmune diagnosis
- Chronic inflammatory conditions affecting fertility
What to Expect at Your Appointment
Clinical Consultation
Dr. Weiss reviews your medical history, fertility records, lab work, and REI recommendations. Eligibility is confirmed and a personalized protocol is established — including timing relative to your IVF or FET cycle.
Pre-Infusion Safety Screening
A brief pre-infusion assessment is completed, including a review of known allergies (particularly to eggs or soy), current medications, and any contraindications. Vital signs are recorded before the infusion begins.
The Infusion
Intralipid is administered intravenously over approximately 60–90 minutes in our private, spa-like infusion suite. The infusion is comfortable — most patients read, work, or rest during the session. Clinical staff monitor you throughout.
Post-Infusion Monitoring & Follow-Up
You are observed for a short period after the infusion before discharge. Dr. Weiss coordinates follow-up with your REI or fertility specialist and adjusts the protocol as needed based on your cycle response and clinical outcomes.
Physician-Supervised. Carefully Monitored.
Intralipid infusions are generally well-tolerated, but as with all IV therapies, they require proper clinical oversight. At Infusion Center of NJ, every infusion is administered and supervised by Dr. Weiss — not a nurse practitioner or aesthetician. We follow strict protocols for patient screening, infusion rate management, and post-infusion observation to ensure your safety at every step.
- Contraindicated in patients with egg or soy allergies — allergy screening is mandatory before first infusion
- Not recommended for patients with severe hyperlipidemia or lipid metabolism disorders
- Infusion rate is carefully controlled to minimize risk of adverse reactions
- All patients are monitored during and after the infusion by trained clinical staff
- Protocol is coordinated with your REI or OB-GYN to align with your fertility treatment timeline
- Lab work review and clinical eligibility assessment required prior to treatment
