    • Presentation at APHA 2018: Medical mistrust as a barrier to male contraception for Black Americans in Los Angeles, CA

Unplanned pregnancy is more common among US minorities. Contraceptives developed to reduce these rates should therefore take minority attitudes into account. Using a structured guide, we conducted focus groups with Black men in Los Angeles, California, exploring their experience with family planning and contraceptives, as well as their willingness to use novel male contraceptives in the future. 

Male Contraceptive Acceptability (Interviews - Latino Men)

  • Primary Investigator(s): BTN, DM & DJS

  • Status: Study approved; Interviewer training and interviews pending. 14 interviews needed.

Unplanned pregnancy is more common among US minorities. Contraceptives developed to reduce these rates should therefore take minority attitudes into account. Using a structured guide, we conducted in-depth interviews with Latino men in Los Angeles, California, exploring their experience with family planning and contraceptives, as well as their willingness to use novel male contraceptives in the future. 

Male Contraceptive Acceptability (Interviews - Asian Men)

  • Primary Investigator(s): BTN, Emmy Jin

  • Status: Study approved; Interviewer training and interviews pending. 

Unplanned pregnancy is more common among US minorities. Contraceptives developed to reduce these rates should therefore take minority attitudes into account. Using a structured guide, we conducted in-depth interviews with Asian men in Los Angeles, California, exploring their experience with family planning and contraceptives, as well as their willingness to use novel male contraceptives in the future. 

Male Contraceptive Acceptability (In-Depth Interviews)

  • Primary Investigator(s): BTN, JG (UCLA), CW (LA BioMed)

  • Status: Data collection closed, analysis and manuscript writing ongoing

  • Manuscript 1: Analyzing data for themes related to participant's experiences in trial

  • Manuscript 2: Analyzing data for themes related to masculinity

  • Project Milestones: Abstract submitted to SFP 2019

Surveys examining the market for male contraceptives may be overestimating men's willingness to consistently use novel methods given that men have no experience with using medications to avoid pregnancy. Explorations of the experiences of men who were actually in active trials may provide more reliable estimates of men's willingness to use male contraceptives in the future. 

Male Contraceptive Safety: a systematic review of off-target effects

  • Primary Investigator(s): BTN, Jennifer Franks, Fiona Yuen

  • Status: Covidence used to sort out relevant articles; currently analyzing journal articles and synthesizing findings; manuscript pending.

  • Project Milestones: Abstract accepted for presentation at ACOG

Surveys examining the market for male contraceptives may be overestimating men's willingness to consistently use novel methods given that men have no experience with using medications to avoid pregnancy. Explorations of the experiences of men who were actually in active trials may provide more reliable estimates of men's willingness to use male contraceptives in the future. 

Men's Access to Emergency Contraception in Los Angeles, CA

  • Primary Investigator(s): BTN, Electra Korn, & Robyn Schickler

  • Status: Data collection closed, analysis and manuscript writing ongoing

  • Manuscript 1: Writing up manuscript on limited services.

  • Project Milestones: Abstract submitted to SFP 2019

While men cannot USE emergency contraception, they should be able to PURCHASE EC for their female partners when needed. Men's access to EC is essential to reducing the financial and logistic burden that women bear. Pharmacists and pharmacy providers with implicit biases about men may be a barrier to access.

Predicting men's condom use at first sex: an analysis of the NSFG

  • Primary Investigator(s): BTN, Jasmine Patel

  • Status: Data analyzed, manuscript in process.

The National Survey of Family Growth is commonly used to explore women's contraceptive use, however the survey also queries men's behaviors as well, creating an opportunity to better understand the populations of men who use or don't use condoms at different time points. Understanding factors associated with condoms at first sex may help to avoid unintended pregnancy. 

Vasectomy & SRH Services Access in California

  • Primary Investigator(s): BTN & Minica Long

  • Status: Data collection closed, analysis and manuscript writing ongoing

  • Manuscript 1: Writing up manuscript on limited services.

  • Project Milestones: Abstract submitted to SFP 2019

California is unique for its FPACT program, which provides coverage for vasectomy services. FPACT should increase vasectomy uptake rates, however if there is a shortage of vasectomy providers, then men will have difficulty accessing the service, regardless of insurance coverage. We surveyed a database of FPACT providers to determine how many were providing vasectomy services in California.

Vasectomy Provider Training Opportunities

  • Primary Investigator(s): BTN, Jasmine Patel

  • Status: IRB approval obtained; survey pending approval; preparing for data collection

  • Expert Consultation: Kari White, Grace Shih (pending)

We know that we need to increase the number of vasectomy providers across the nation. Therefore, we need experts who would be willing to train others, however vasectomy is not a priority for urological surgeons who commonly perform vasectomy. Would they be willing to train non-urologists in order to expand the pool of potential vasectomy providers?

Vasectomy: Follow-up & Completion among "Interested" Men

  • Primary Investigator(s): BTN, Brittany Klooster

  • Status: Protocol and IRB approval pending; database design

We know that we need to increase the number of vasectomy providers across the nation. Therefore, we need experts who would be willing to train others, however vasectomy is not a priority for urological surgeons who commonly perform vasectomy. Would they be willing to train non-urologists in order to expand the pool of potential vasectomy providers?

Withdrawal (coitus interruptus):
An evaluation of the pre-ejaculate in withdrawal or "pulling out"

  • Primary Investigator(s): BTN, Jasmine Patel

  • Status: Protocol and IRB approval pending; database design

  • Funding source: The Society for Family Planning

“Pulling out” or withdrawal is commonly used to prevent pregnancy, for better or worse. We STILL don't know very much about how to use it and how effective it really is. Some men have used withdrawal their whole lives without any unwanted pregnancies; others have been less successful...We want to know why!

Sexually Transmitted Diseases:
Rates of Patient-Delivered Partner Therapy in Los Angeles

  • Primary Investigator(s): BTN, Nicholas Jeffrey, Emily Chang

  • Status: Pending approval from IRB continuing review; data collection on hold. 

The treatment of any sexually-transmitted infection should be paired with counseling on the need to treat the patient's sexual partner. However, these conversations do not always occur -- physicians may be reluctant to discuss relationship issues or may not feel comfortable prescribing treatment for the partner. 

Advanced Paternal Age and the risk of Spontaneous Abortion:
an analysis of data from the National Survey of Family Growth

  • Primary Investigator(s): BTN, Erica Chang

  • Status: Manuscript currently under review with AJOG.

  • Project milestones: 2017 Oral presentation at ASRM

As the average paternal age continues to increase, couples considering pregnancy need to be fully informed about additional risks incurred by paternity at advanced age. We use data from the National Survey of Family Growth to exam the risk of spontaneous abortion or miscarriage with advancing age.

Gender biases in male medical student education: a literature review

  • Primary Investigator(s): BTN, Chris Douglas, Ravali Reddy

  • Status: Data collection complete; data analysis and validation on-going. Manuscript in process. 

  • Project milestones: Abstract accepted for regional ACOG 2018

Gender biases may lead to male medical student being turned away from opportunities to treat some female patients in the clinical setting. As student's rely on their clinical experiences to make decisions about future residency training, such negative experiences may lead some trainees to consider other rotations. We reviewed the literature to better understand the trainee experience of gender bias. 

Expectations for contraceptive clinical trial compensation: a survey

  • Primary Investigator(s): BTN, Robyn Schickler, Ravali Reddy

  • Status: Protocol completed and IRB approved; data collection complete; analyzing data and manuscript-writing.

  • Project milestones: Submitted abstract to SFP 2019

Contraceptive studies face difficult recruitment since experimental regimens are given to healthy individuals who may experience off-target effects or adverse events from new drugs. Compensation can help recruiting, however the amount of compensation to give that balances and prevents untoward incentivization or indirect coercion lacks any baseline evidence. 

Men's Sexuality and Sex Education - the Asian experience

  • Primary Investigator(s): BTN, Ravali Reddy, Nhat Ngo

  • Status: Protocol completed and IRB approved; revising survey and exploring opportunities for expanding to a national population sample.

We know that we need to increase the number of vasectomy providers across the nation. Therefore, we need experts who would be willing to train others, however vasectomy is not a priority for urological surgeons who commonly perform vasectomy. Would they be willing to train non-urologists in order to expand the pool of potential vasectomy providers?
