José Balmaceda Riera built a respected career in reproductive medicine before becoming associated with one of the most troubling fertility scandals in American medical history. Born in Chile in 1948, he trained as an obstetrician and reproductive endocrinologist, fled Augusto Pinochet’s dictatorship with his young family, and later contributed to early research on gamete intrafallopian transfer, better known as GIFT.
To a wider public, he is also known as the father of actor Pedro Pascal. That family connection has brought renewed interest in Balmaceda’s life, but his biography extends far beyond celebrity. It includes political exile, medical research, private practice in California, allegations involving patients’ eggs and embryos, years outside the United States, and a later federal plea involving unreported income.
As of July 2026, Balmaceda is 77 years old. His exact residence, current employment, and present medical status are not publicly confirmed through a recent authoritative source.
Early Life in Chile
José Balmaceda Riera was born on August 22, 1948, in Santiago, Chile. Public biographical accounts describe him as having grown up in a financially comfortable family. His father was involved in timber-related businesses, while his mother reportedly operated a women’s clothing shop.
He attended San Ignacio, a prominent school in Santiago, before studying medicine at the Pontifical Catholic University of Chile. He completed his medical degree in 1974 and began training in obstetrics and gynecology at the University of Chile Hospital.
His early professional years unfolded during one of the most violent periods in modern Chilean history. General Augusto Pinochet seized power in the military coup of September 11, 1973, overthrowing President Salvador Allende. The dictatorship that followed carried out widespread arrests, torture, killings, disappearances, and political persecution.
Balmaceda married Verónica Pascal Ureta, a child psychologist whose family had connections to Chile’s political left. Their relationship and family history would soon become inseparable from the political crisis surrounding them.
Marriage to Verónica Pascal Ureta
Verónica Pascal Ureta came from a family with strong political ties. Her cousin Andrés Pascal Allende was a leader of the Revolutionary Left Movement, commonly known by its Spanish initials, MIR. The organization opposed Pinochet’s military government and became a major target of state repression.
José and Verónica were accused of sheltering Andrés Pascal Allende. With their safety at risk, they went into hiding and eventually sought protection at the Venezuelan embassy in Santiago. Their children were very young at the time, and Pedro Pascal was still an infant.
The family was allowed to leave Chile and moved to Denmark in 1976 as political refugees. They later relocated to the United States when Balmaceda received an opportunity to continue his medical training in Texas.
Verónica remained a defining figure in the family’s life. She died in 1999, a loss that Pedro Pascal has described publicly as deeply affecting him and his siblings. Details about the couple’s marriage beyond the publicly documented family history have remained largely private.
Children and Family Life
José Balmaceda Riera and Verónica Pascal Ureta had four children: Javiera Balmaceda, José Pedro Balmaceda Pascal, Nicolás Balmaceda, and Lux Pascal.

Their best-known child, José Pedro, was born in Santiago on April 2, 1975. He later became internationally famous under the professional name Pedro Pascal, appearing in television series and films including Game of Thrones, Narcos, The Mandalorian, The Last of Us, and Gladiator II.
Javiera Balmaceda has worked in the entertainment industry, including senior roles connected to content production and acquisitions. Lux Pascal is an actress and activist who has pursued performance work in Chile and abroad. Nicolás Balmaceda has maintained a lower public profile, and reliable details about his professional life are limited.
The family experienced repeated relocations during Pedro’s childhood, including periods in Texas and California. Their history combined political displacement with the demands of José’s medical career. Although Pedro later adopted his mother’s surname professionally, he has appeared publicly with his father and siblings on several occasions.
In November 2024, José attended the London premiere of Gladiator II with Pedro and Lux. The appearance was one of his most visible recent public moments, but it did not include a detailed interview about his own life or work.
Medical Training in the United States
After arriving in the United States, Balmaceda resumed his medical career at the University of Texas Health Science Center in San Antonio. He completed a residency in obstetrics and gynecology in 1980 and later received advanced training in reproductive endocrinology.
His work developed at a time when assisted reproduction was moving quickly from experimental science into clinical treatment. In vitro fertilization had produced its first widely recognized live birth in 1978, and doctors were searching for other ways to help patients experiencing infertility.
Balmaceda worked closely with reproductive specialist Ricardo Asch. Their research focused in part on gamete intrafallopian transfer, or GIFT, a procedure in which doctors retrieved a woman’s eggs and placed them with sperm directly into the fallopian tube. Unlike IVF, fertilization was intended to occur inside the body rather than in a laboratory dish.
Balmaceda coauthored early medical papers on the technique during the 1980s. Those publications established him as a participant in the early development and clinical study of GIFT, though claims that he invented IVF or single-handedly created the procedure are inaccurate.
Career in California
Balmaceda moved to California in the mid-1980s and joined Asch in a fertility practice connected to the University of California, Irvine. Sergio Stone later became another senior physician in the operation.
The clinic combined private fertility treatment, university facilities, research, and insurance billing. Patients often sought care after years of unsuccessful attempts to become pregnant, making trust, accurate recordkeeping, and informed consent especially important.
Balmaceda also worked through a fertility program at Saddleback Memorial Medical Center. Accounts from the period described him as confident and reassuring with patients. He developed a successful medical practice and became established in Southern California’s growing fertility-treatment sector.
That career changed sharply in 1995, when investigative reporting exposed evidence of unauthorized egg and embryo transfers at the UC Irvine fertility center.
The UC Irvine Fertility Scandal
The Orange County Register began publishing its investigation into the clinic in May 1995. Reporters found evidence that eggs retrieved from some patients had been used to treat other women without the original patients’ knowledge or written consent.

The newspaper’s work later received the 1996 Pulitzer Prize for investigative reporting. The findings raised serious questions about the conduct of individual doctors as well as the university’s failure to supervise a profitable clinic operating with weak records and blurred lines between public resources and private business.
The alleged misconduct did not involve only a simple laboratory mix-up. Records indicated that reproductive material may have been redirected intentionally in multiple cases. Some patients learned years later that eggs connected to their treatment had resulted in children born to other women.
Balmaceda performed an embryo-transfer procedure in at least one case later identified by investigators. He said he did not remember the specific procedure and denied knowingly participating in unauthorized transfers. His legal representatives maintained that he had not intentionally used patients’ reproductive material without permission.
University reviews and later reporting linked Balmaceda and his colleagues to serious failures involving consent, documentation, billing, and oversight. The exact number of affected patients remains uncertain because records were incomplete, missing, altered, or difficult to reconcile. Published estimates have varied, but the scandal involved dozens of patients, multiple births, and more than 100 civil claims.
What Was Proven and What Remained Disputed
Balmaceda was never criminally convicted of stealing eggs or embryos. That distinction matters because many online summaries incorrectly describe his later guilty plea as an admission to fertility-related misconduct.
At the time the clinic operated, California did not have a specific criminal law clearly prohibiting the non-consensual use of eggs or embryos. The scandal exposed that legal gap and helped lead to a 1996 law making it a felony to use reproductive material for a purpose not authorized in a signed consent form.
Federal prosecutors instead pursued allegations connected to insurance billing and financial conduct. In 1996, Balmaceda and Sergio Stone were indicted on mail-fraud charges involving allegedly false insurance claims.
Balmaceda had returned to Chile before the federal case progressed. He remained outside the United States for many years, and efforts to secure his return were complicated by jurisdiction and extradition issues. He was arrested in Argentina in 2001 but failed to appear at a later hearing after being released on bail.
More than two decades later, he returned to the United States and surrendered. In 2022, he entered a plea agreement involving the underreporting of cash income received by the medical practice for the 1991 and 1992 tax years.
The plea concerned tax-related conduct, not unauthorized egg or embryo transfers. Balmaceda continued to deny knowingly taking part in procedures performed without patient consent.
The Patients and Families Affected
The UCI scandal had consequences that extended far beyond medical billing or university administration. Patients had entrusted doctors with genetic material capable of creating children. Unauthorized use therefore affected bodily autonomy, parenthood, medical history, and personal identity.
One widely reported case involved Renée Ballou, whose eggs were retrieved during fertility treatment in 1987. Evidence later showed that some of those eggs had been used to treat another patient, Carole LieberWilkins, without Ballou’s permission. LieberWilkins gave birth to a son, Daniel, in 1988.
Ballou did not learn what had happened until a journalist contacted her in 1995. Decades later, the families developed contact, and Ballou met Daniel in person in late 2024. Their experience illustrated how the effects of fertility misconduct can continue across generations.
The University of California paid millions of dollars to settle claims connected to the clinic. Settlements do not establish every allegation as proven fact, but their scale reflected the number of patients who reported harm and the institution’s exposure to legal responsibility.
The scandal also changed expectations for fertility clinics. Written consent, accurate labeling, clear custody records, identity checks, and independent oversight became harder to treat as administrative details. The case showed that failures in those systems could permanently alter families.
Return to Chile
Balmaceda returned to Santiago in 1995 as the California investigations intensified. He later became associated with fertility medicine in Chile, including work connected to Clínica Las Condes and other reproductive-health services.
Some older professional profiles continue to list his medical credentials and teaching roles. Those pages do not always include clear publication or update dates, so they cannot confirm whether he remains in active medical practice in 2026.
His exact current residence is also not publicly confirmed. Available information indicates that he has spent much of his later life in Chile, while maintaining contact with his children and appearing at occasional family events.
Balmaceda has not given a widely reported recent interview offering a full account of the UCI scandal, his return to Chile, or his current circumstances. As a result, major parts of his later life remain outside the public record.
Net Worth and Income Sources
José Balmaceda Riera’s net worth is not publicly confirmed. No dependable financial disclosure, court record, business filing, or authoritative report provides a verified estimate of his present wealth.
His known income came primarily from his medical career, including academic work, reproductive-endocrinology practice, fertility procedures, and private clinic operations. His California practice appears to have generated substantial revenue, but gross clinic income cannot be treated as personal net worth.
Online figures that assign him a specific fortune should be viewed cautiously. They generally lack documentation and may confuse his son Pedro Pascal’s earnings with José’s finances. There is no reliable basis for claiming that José Balmaceda Riera is worth a particular amount as of 2026.
Public Image and Legacy
Balmaceda’s public reputation contains sharp contrasts. He was a political refugee forced to rebuild his career abroad, a trained specialist involved in early assisted-reproduction research, and a physician connected to a scandal centered on failures of consent.
His exile deserves recognition as part of the family’s history. Leaving Chile under threat shaped his children’s lives and created the circumstances in which Pedro Pascal grew up in the United States. That experience, however, does not answer the ethical questions raised by his later medical career.
The absence of a conviction for stealing reproductive material should not be confused with proof that no patients were harmed. Investigative reporting, university findings, civil settlements, and reconstructed clinic records documented serious wrongdoing within the program. Balmaceda disputed that he knowingly participated, and that denial remains part of the record.
His legacy is therefore neither a simple story of professional achievement nor one defined only by scandal. It is the record of a physician whose career developed alongside major advances in fertility treatment and whose name later became linked to a case that changed how reproductive consent was understood in California.

Conclusion
José Balmaceda Riera’s life joins together political persecution, family migration, medical ambition, and disputed professional conduct. He rebuilt his career after fleeing Chile and participated in research during a formative period for fertility treatment.
His greatest public controversy concerned a duty more basic than scientific progress: patients must control how their reproductive material is used. The UCI scandal demonstrated the damage that follows when consent, documentation, and institutional supervision fail.
Balmaceda’s later tax plea resolved only one part of the legal history. It did not settle every ethical question surrounding the clinic, nor did it amount to an admission that he knowingly transferred eggs or embryos without authorization.
Today, interest in him is often driven by Pedro Pascal’s fame. Yet José Balmaceda Riera’s own public place rests on a more difficult record—one that includes exile and achievement, but also a medical scandal whose effects remain personal for the families involved.
