Reproductive Endocrinologist in NJ | Damien Fertility Partners
A reproductive endocrinologist is the most specifically trained physician you can see for infertility. The title is not interchangeable with OB/GYN, fertility doctor, or fertility specialist, though those terms are often used loosely. An RE has completed a unique training pathway that covers complex reproductive issues, from hormonal diagnostics to IVF cycle management.
New Jersey is home to approximately 87 reproductive endocrinologists across roughly 20 practices and 40 locations. Damien Fertility Partners employs two board-certified REs, both of whom practice from offices in Shrewsbury, Newark, and Jersey City.
What It Takes to Become a Reproductive Endocrinologist
The credential behind the title is long and specific. A reproductive endocrinologist completes four years of medical school, a four-year residency in obstetrics and gynecology, and then a three-year fellowship in reproductive endocrinology and infertility (REI). That fellowship is where the specialization happens.
During the REI fellowship, training focuses on the hormonal mechanisms governing ovulation, implantation, and early pregnancy, as well as the interventions used when those mechanisms fail.
Fellows manage IVF cycles under supervision, learn to interpret complex hormonal panels, perform ultrasound-guided procedures including egg retrievals, counsel patients on genetic testing options, and work directly alongside embryology lab teams. The fellowship also includes formal training in reproductive surgery and research.
After completing the fellowship, physicians sit for a board certification examination administered by the American Board of Obstetrics and Gynecology (ABOG). Board certification in REI requires passing both a written qualifying exam and an oral certifying exam.
Not every physician who completes a fellowship achieves board certification, and not every fertility practice requires it. At Damien Fertility Partners, both physicians are board-certified in reproductive endocrinology and infertility.
That training pathway, roughly 13 to 15 years from medical school through board certification, produces a physician with a depth of knowledge in reproductive hormones, assisted reproduction, and embryology that no other specialty provides.
What a Reproductive Endocrinologist Treats
The scope of an RE’s practice extends well beyond IVF. Reproductive endocrinologists diagnose and manage a range of conditions that affect fertility and reproductive health.
Ovulatory disorders, including PCOS, hypothalamic amenorrhea, and hyperprolactinemia, are among the most common diagnoses an RE evaluates. These conditions disrupt the hormonal signals that trigger ovulation, and treatment often begins with medication before progressing to more advanced interventions.
Tubal factor infertility involves blocked or damaged fallopian tubes that prevent the egg and sperm from meeting. An RE diagnoses this through hysterosalpingogram (HSG) or laparoscopy and determines whether surgical repair or IVF is the more appropriate path.
Uterine abnormalities such as fibroids, polyps, scar tissue (Asherman syndrome), and structural anomalies can interfere with implantation or increase miscarriage risk. An RE identifies these through imaging and saline sonography and may coordinate surgical correction with the practice’s surgical team.
Male factor infertility accounts for roughly 40% of infertility cases. An RE orders and interprets semen analysis, assesses hormonal contributions to male subfertility, and determines when procedures like ICSI (intracytoplasmic sperm injection) are warranted during IVF.
Recurrent pregnancy loss, defined as two or more consecutive miscarriages, requires a diagnostic workup that includes chromosomal analysis, uterine evaluation, hormonal assessment, and, in some cases, immunological testing. An RE coordinates this workup and manages subsequent pregnancies with closer monitoring.
Diminished ovarian reserve and age-related fertility decline are evaluated through AMH (anti-Mullerian hormone), FSH (follicle-stimulating hormone), and antral follicle counts. An RE uses these markers to counsel patients on their reproductive timeline and to design treatment protocols calibrated to their ovarian response.
Fertility preservation for patients facing cancer treatment, gender-affirming care, or elective egg freezing is managed by an RE from ovarian stimulation through retrieval and vitrification.
The Reproductive Endocrinologists at Damien Fertility Partners
Dr. Miguel Damien, M.D. founded the practice in 1989, establishing what was then the first successful IVF program in Monmouth and Ocean County under the name East Coast IVF. He graduated from Dartmouth Medical School, completed his OB/GYN residency at Harvard Medical School, and trained in reproductive endocrinology and infertility at both Harvard and the University of Connecticut.
Dr. Damien is board-certified in REI by the American Board of Obstetrics and Gynecology, fluent in Spanish, and has been practicing reproductive medicine in New Jersey for more than 35 years. Castle Connolly has named him a Top Doctor in the NY Metro Area six times (2005, 2007, 2008, 2010, 2017, 2018) and an Inside Jersey Magazine Top Doctor for Women ten times.
Dr. Barry Perlman, D.O., FACOG joined Damien Fertility Partners in 2023. He studied molecular biology at Lehigh University, earned his medical degree at Rowan University School of Osteopathic Medicine, and completed both his OB/GYN residency and REI fellowship at Rutgers New Jersey Medical School.
Dr. Perlman is board-certified in REI and a Fellow of the American College of Obstetricians and Gynecologists (ACOG). His clinical interests include PCOS, ovarian aging, male factor infertility, fertility preservation, and the effects of endocrine disruptors on reproductive health.
He has published peer-reviewed research on endocrine disruptors and fertility in ASRM’s Fertility and Sterility Reports and presented at U.S. and European conferences. Dr. Perlman sees patients in person across all three locations and offers virtual consultations.
The Lab and Technology Behind the REI
A reproductive endocrinologist’s decisions are only as good as the lab that executes them. The embryology laboratory at Damien Fertility Partners holds accreditation from the College of American Pathologists (CAP), the FDA, and the NJ State Department of Health, all with zero deficiencies.
The lab uses CHLOE, Fairtility’s AI-powered embryo monitoring system. CHLOE continuously tracks embryo development inside the incubator without disturbing the culture environment, then produces a developmental timeline for the RE to review with each patient.
In 2023, the practice reported a 100% elective single-embryo transfer rate for patients under 35 and an 81.8% live-birth rate per new patient in that age group, according to SART data. Clinic-to-clinic comparisons should be interpreted with caution due to differences in patient populations.
Preimplantation genetic testing (PGT) is performed on-site, providing the RE with detailed chromosomal information before making transfer recommendations.
Insurance and Access
New Jersey’s fertility insurance mandate requires qualifying group health plans covering 50 or more employees to cover up to four completed egg retrievals per lifetime. The 2024 expansion removed restrictions based on age, relationship status, and sexual orientation.
Damien Fertility Partners works with most insurance carriers and employs a dedicated bilingual Insurance Verification Specialist. Financing through CapexMD is available for patients who need it, with loans pre-approval within 24 hours.
The practice operates bilingually in English and Spanish. Dr. Damien is fluent in Spanish, and Spanish-speaking providers staff all three offices. The entire website is available in Spanish, and the practice’s Diversity and Inclusion commitment includes no BMI-based care limitations and dedicated LGBTQ+ family building support.
Frequently Asked Questions
What is a reproductive endocrinologist?
A reproductive endocrinologist is a physician who has completed a four-year OB/GYN residency followed by a three-year fellowship in reproductive endocrinology and infertility. This additional training covers hormonal disorders affecting fertility, IVF cycle management, embryology, reproductive surgery, and genetic testing. Board certification is granted by the American Board of Obstetrics and Gynecology after passing written and oral examinations.
How is a reproductive endocrinologist different from a fertility specialist?
The terms are often used interchangeably, but “reproductive endocrinologist” refers specifically to a physician who has completed an accredited REI fellowship and achieved board certification.
“Fertility specialist” is a broader, informal term that may include non-board-certified physicians or advanced practice providers. At Damien Fertility Partners, both physicians are board-certified reproductive endocrinologists.
When should I see a reproductive endocrinologist in NJ?
Couples under 35 should consult an RE after 12 months of trying to conceive. For patients 35 and older, the recommendation is six months. Earlier visits are warranted for irregular cycles, known PCOS or endometriosis, recurrent pregnancy loss, prior cancer treatment, male factor concerns, or a desire to freeze eggs.
How many reproductive endocrinologists practice in New Jersey?
U.S. News lists approximately 87 reproductive endocrinologists across the state, practicing at roughly 20 distinct fertility clinics and 40 locations.
Does Damien Fertility Partners accept insurance for RE visits?
Yes. The practice works with most insurance carriers. New Jersey’s fertility mandate covers up to four egg retrievals per lifetime for qualifying group plans. A bilingual Insurance Verification Specialist confirms your coverage before treatment. Financing through CapexMD is also available.
