“Every time I make a film, it’s because something pissed me off,” said Academy Award-nominated documentarian Renee Tajima-Peña, professor of Asian American studies at UCLA.

It was a personal impetus that drove the creation of “No Más Bebés,” her award-winning 2015 film that tells the story of Mexican immigrant women who were permanently sterilized at Los Angeles County-USC Medical Center hospital in the late 1960s and early 1970s — either without their consent or under extreme duress to consent to a tubal ligation procedure. A group of them launched an unsuccessful class action suit, Madrigal v. Quilligan, against the hospital in 1975.

As part of its “Radical Women: Latin American Art, 1960–1985” exhibition, produced in conjunction with the Getty Initiative’s Pacific Standard Time: LA/LA, the Hammer Museum at UCLA will screen “No Más Bebés” Oct. 24 at 7:30 p.m. followed by a Q&A with Tajima-Peña.

“These women went to the hospital for emergency C-sections,” Tajima-Peña said. “They were distressed, terrified their babies would die, often hemorrhaging and medicated. Most did not speak English and they were often given these English-language consent forms, while in labor, before they could get care, and some of them did not consent at all.”

Some women would not discover what happened to them until years later after trying to get pregnant again, and failing.

Tajima-Peña first heard the story of these women from her neighbor at the time, historian Virginia Espino, who became the film’s co-producer. At the time, she led the Latino program at the UCLA Library's Center for Oral History Research and is now a lecturer in the Chicana and Chicano studies department. The two women had small children around the same age and would get together, talking about their work as their sons played nearby. Tajima-Peña was basking in her choice to become a mom at the time.

“I remember thinking ‘this is fabulous, why did I wait so long?’” she said. “I grew up middle class always thinking ‘oh, if I want to have a baby I can have a baby.’”

The story of the women involved in Madrigal v. Quilligan made her think differently about the fight for reproductive rights.

“One thing that Virginia always talked about was motherhood as a political act. These women in the 1970s were asserting their values of being a mother,” Tajima- Peña said. “If you look at U.S. feminist history at that point, that idea was kind of contrary to the movement, at least for middle-class women. For my generation the fight for reproductive rights really centered around safe access to abortion.

“But when I heard about these women, it really hit me in the gut,” she said. “It just outraged me.”

Claudio Rocha Renee Tajima-Peña spent five years working on “No Más Bebés.”

At UCLA, Tajima-Peña teaches courses in EthnoCommunications. Her film credits include the documentaries, “Calavera Highway,” “Skate Manzanar,” “Labor Women,” “My America ... or Honk if You Love Buddha” and “Who Killed Vincent Chin?”

For “No Más Bebés” Tajima-Peña set out on a five-year mission to tell their stories. She and Espino interviewed as many of the women as they could who were plaintiffs in the Madrigal v. Quilligan case brought against Dr. Edward James Quilligan, who was head of the women’s hospital at the time. She also interviewed Quilligan along with several other doctors, including Bernard Rosenfeld, an intern at the time, who was the whistleblower about the methods his workplace employed to sterilize women.

The fact that 10 of those women bravely stepped forward to speak out about what happened to them as part of the lawsuit was radical in and of itself, Tajima-Peña said.

“They were at the bottom of the social hierarchy,” she said. “They were Mexican immigrant women, they were homemakers, factory workers, restaurant workers. And they went up against some very powerful white men. They lost their case, but the fact that they brought this practice to light resulted in real change.”

Many were not eager to re-live the experience for the film, she said. Some of the women involved still hadn’t shared what they had been through with their own children, who were too young at the time to remember. For some, their now-grown children convinced them to participate in the film after finally learning the truth.

As Tajima-Peña and Espino conducted research they uncovered a multilayered UCLA connection to the story.

Espino, who is speaking at the Hammer Museum on Oct. 29 on a panel about forced sterilization in U.S. history, was instrumental in preserving documents related to the case, which now reside in the Chicano Studies Research Center in an archive called the Carlos Vélez-Ibáñez Sterilization Papers. Vélez-Ibáñez was an anthropology professor at UCLA who testified on behalf of the women and donated all of his records to UCLA. His activist research on the topic was unheard of at the time, Tajima-Peña said.

And Antonia Hernandez, the young Latina lawyer who filed the case and represented the sterlized women had just graduated from UCLA School of Law. Charles Nabarrete, who was just a few years out of UCLA Law, served as lead counsel.

“At that time there were very few Chicanos not only in law school but in the state and U.S. bar at all,” Tajima-Peña said. “They went up against these powerful institutions — the hospital, the county state and federal government — working out of a storefront in Boyle Heights.”

Most of the doctors involved believe they did nothing wrong, Tajima-Peña said, based on her interviews with them. And for some, that might be true, she believes.

But there was a cultural tension in the early 1970s around the population explosion of the previous decades, one that prompted concerted efforts to promote sterilization, especially among minority communities across the United States. Sterilization rates in California were among the highest in the country.

At the same time as the events from her film, a widespread campaign to promote voluntary sterilization resulted in one-third of the population of women of childbearing age in Puerto Rico undergoing such procedures.

A strong and well-financed crop of family planning services available at the time played a role, Tajima- Peña said.

“They were good programs because women who could otherwise not afford this whole menu of contraceptive services, got them, so they were really beneficial,” she said. “But there also was this environment for abuse — a perfect storm created by well-financed family planning initiatives, attitudes about immigrants and population-explosion fears.”

The furor surrounding these women’s stories in the wake of their federal suit did lead to new standards in consent for sterilization, especially for non-English speakers.

But for the women in “No Más Bebés,” the pain lingers, Tajima-Peña said.

“Most of the doctors I interviewed contend they did nothing wrong — that these women did consent to sterilization but maybe had post-surgery regrets or a change of heart,” she said. “On one hand, trying to be an objective filmmaker, you have to think that’s plausible … until I met the women themselves.

“It was 40 years later and their emotions were still so raw, they still felt so wronged and violated. To me it did not read as regret — they had very precise memories of what happened to them.”
