Jennifer Knudtson, MD

About

A May 2021 announcement put Jennifer Knudtson, MD, on the San Antonio staff of Aspire Fertility, seeing patients at the practice’s Stone Oak location. The clinic’s description of her carries one credential line and one start date, and the credential line is unusually specific: double board certification in obstetrics and gynecology and in reproductive endocrinology and infertility.

The other named item is external. Castle Connolly Top Doctors, an independent physician directory rather than the clinic’s own marketing, lists her. A directory listing is not a license, a hospital appointment or an outcome statistic, but it comes from a party with no commercial relationship to the practice.

Everything else is a gap, and the gap is the accurate picture here. Our sources do not name her medical school, residency program or fellowship program, do not give a pre-2021 work history, and do not describe a subspecialty procedure list. The one research item attached to her name is Fertilo in-vitro maturation work dated 2026 in our notes, with no protocol, site or enrollment detail published. Ask the practice for the training history if you want it; it is not on the public record we checked.

Clinical Expertise

• IVF: her first listed practice area, covering stimulation, monitoring, retrieval and transfer at the Stone Oak site, which is the address the clinic pairs with the IVF laboratory.
• Preimplantation genetic testing (PGT): genetic screening of embryos before transfer, the second area in our record — a conversation about which embryos to transfer, and how many.
• LGBTQ+ family building: the third listed area. Our record tags this as a practice area for her; the specifics of donor-sperm protocols, partner-carried cycles and legal paperwork are worth confirming with the clinic directly.
• In-vitro maturation (IVM): our notes place her in Fertilo IVM research dated 2026, a laboratory technique for maturing eggs outside the body. Research participation is not a treatment offer, so ask whether any of it reaches patient care.
• Gynecologic base under the subspecialty: with certification in both obstetrics and gynecology and reproductive endocrinology and infertility, the physician reviewing your ultrasound is certified in the underlying specialty as well as the fertility one.

Why Choose Dr. Jennifer Knudtson

Two board certifications, stated by the clinic. Both specialty certificates are named in Aspire’s own text, not inferred from a training line — the clearest credential statement available in this record.

A third-party name on the file. Castle Connolly Top Doctors listing comes from outside the practice, which makes it checkable in a way marketing copy is not.

Still at the address she started at. She began at Stone Oak in May 2021, and the location record still places her there, so the office in this profile is the office you would book.

Connected to a laboratory technique most patients have not heard of. If you are interested in in-vitro maturation because stimulation response is a concern, our notes link her to Fertilo IVM work in 2026 — the entry point for a question, not a promise.

Professional Affiliations

Certified in obstetrics and gynecology and in reproductive endocrinology and infertility, per her Aspire profile, with the certifying body not named in our sources; no society memberships are listed either. She has practiced at Aspire Fertility San Antonio since May 2021. The location record this page is built from pairs the Stone Oak site with Alamo Heights, while the clinic’s own announcement named only Stone Oak, so treat the second address as a scheduling question rather than a given. Cycle outcomes in our sources are reported for the San Antonio reporting entity as a whole, not by individual physician, and her published training institutions and personal results figures are not in the material we hold.

Suitable For

• Patients booking at Stone Oak who want a double board-certified reproductive endocrinologist at the address with the clinic’s IVF laboratory
• LGBTQ+ patients and couples whose plan involves donor gametes or a partner carrying the pregnancy
• Patients considering PGT, whether for age, recurrent loss or a known genetic risk
• Patients with poor stimulation response who want to ask, with a name in front of them, whether in-vitro maturation is available anywhere in practice
• Readers of third-party directories: a Castle Connolly listing is the kind of external signal you can verify yourself before the first appointment
