Physicians

Sher Fertility Solutions is the current practice led by Dr. Geoffrey Sher, a pioneer in the IVF and assisted reproductive technology world. Sher established the first private IVF clinic in the United States in 1982, later founding the Sher Institute for Reproductive Medicine in 1999.

Dr. Sher and Dr. Drew Tortoriello have spent decades at the forefront of IVF research, and their practice is particularly well known for taking on complex cases: patients with repeated IVF failures, recurrent pregnancy loss, unexplained infertility, and imore. More than 60% of Dr. Sher's patients have experienced multiple prior IVF failures before arriving at his practice. Sher Fertility Solutions offers IVF, IUI, egg freezing, genetic testing, and third-party reproduction options including surrogacy and egg donation.

The Genesis Group is proud to work alongside Sher Fertility Solutions as a trusted affiliate. We are a leading surrogacy, egg donation, and sperm donation agency that has been supporting intended parents on their path to parenthood since 2003.

We handle everything outside the clinic, from matching you with a carefully screened surrogate or egg donor, managing the relationship, coordinating legal and logistical details, to providing end-to-end support through birth and beyond.

How a Fertility Clinic and a Surrogacy or Egg Donation Agency Work Together

Intended parents often find they need two separate organizations working in parallel. While a clinic is integral for the medical side of the journey, an agency exists to handle everything else: finding qualified donor and surrogate candidates, coordinating with attorneys and escrow companies, managing matches and communications between all parties, and more. The two roles are distinct, and both matter.

A clinic like Sher Fertility Solutions is responsible for all clinical decision-making and procedures. Once a surrogate or donor has been identified and cleared, your clinic manages:

Full medical evaluation and screening of your surrogate or donor
Cycle monitoring and treatment protocol
The egg retrieval, sperm deposit, or embryo transfer itself
Clinical monitoring of the pregnancy through its early stages

An agency like The Genesis Group owns the non-medical process. We recruit, screen, and maintain a pool of high-caliber surrogate and donor candidates, guide you through matching, manage the ongoing relationship between all parties, and coordinate the legal, financial, and logistical components that surround a third-party journey.

The two teams work alongside each other from early in the process — your clinic handles what happens in the exam room, we handle everything outside of it — and both communicate directly throughout so your journey moves forward without gaps.
