  • “I believe there’s always a personal treatment option for you that’s unique.”

People value fertility more than they do most things. Many women only have one or two children in their entire life, and will often go to great lengths in order to conceive. It appeals to me to work with motivated patients who really want to achieve their goal.

It’s very rewarding to care for a patient who seems to have no possible hope of having a child. Some patients have genetic predispositions, previous surgeries, or other unique situations that lead to loss of fertility. We have therapies now where we can restore fertility to those who have lost it. That’s truly life-changing.

It’s still amazing to me that we are developing techniques that no one else has ever figured out. You see these taglines saying “we’re developing tomorrow’s advances”, and they may sound corny but in reality it’s true. We really do have the ability to change someone’s life.

I will partner with you to identify innovative treatment options, and achieve your goal in a timely fashion. I believe there’s always a personal treatment option for you that’s unique.

Relationship between paternal somatic health and assisted reproductive technology outcomes. Fertility and sterility Eisenberg, M. L., Li, S., Wise, L. A., Lynch, C. D., Nakajima, S., Meyers, S. A., Behr, B., Baker, V. L. 2016; 106 (3): 559-565

Abstract

To study the association between paternal medical comorbidities and the outcomes of assisted reproductive technology (ART).Retrospective cohort study.Academic reproductive medicine center.We analyzed fresh ART cycles uszing freshly ejaculated sperm from the male partner of couples undergoing ART cycles from 2004 until 2014. We recorded patient and partner demographic characteristics. The cohort was linked to hospital billing data to obtain information on selected male partners' comorbidities identified using ICD-9-CM codes.None.Fertilization, clinical pregnancy, miscarriage, implantation, and live-birth rates as well as birth weights and gestational ages.In all, we identified 2,690 men who underwent 5,037 fresh ART cycles. Twenty-seven percent of men had at least one medical diagnosis. Men with nervous system diseases had on average lower pregnancy rates (23% vs. 30%) and live-birth rates (15% vs. 23%) than men without nervous system diseases. Lower fertilization rates were also observed among men with respiratory diseases (61% vs. 64%) and musculoskeletal diseases (61% vs. 64%) relative to those without these diseases. In addition, men with diseases of the endocrine system had smaller children (2,970 vs. 3,210g) than men without such diseases. Finally, men with mental disorders had children born at an earlier gestational age (36.5 vs. 38.0weeks).The current report identified a possible relationship between a man's health history and IVF outcomes. As these are potentially modifiable factors, further research should determine whether treatment for men's health conditions may improve or impair IVF outcomes.

Practice patterns, satisfaction, and demographics of reproductive endocrinologists: results of the 2014 Society for Reproductive Endocrinology and Infertility Workforce Survey FERTILITY AND STERILITY Barnhart, K. T., Nakajima, S. T., Puscheck, E., Price, T. M., Baker, V. L., Segars, J. 2016; 105 (5): 1281-1286

Abstract

To identify the current and future state of the practice of reproductive medicine.Cross-sectional survey.Not applicable.None.Not applicable.The survey included 57 questions designed to assess practice patterns/metrics and professional satisfaction and morale.A total of 336/1,100 (31%) responded, and they were 38% women, 61% men, and 76% Caucasian, with a mean age of 54. Respondents averaged 2.3 jobs and averaged 53hours of work per week: 44% work in academia and 50% in private groups. Average practice size was 5.5, with an average of 470 fresh IVF cycles performed per year. Percent effort included 63% infertility, 10% endocrinology, 10% surgery, and 9% research. Respondents performed an average of 13 major surgeries, 69 minor surgeries, and 128 oocyte retrievals per year. A total of 60% were salaried, and 40% were equity partners. Compensation was highly skewed. Greater than 84% had a positive morale and had a positive view of the future, and 92% would again choose REI as a career. The most satisfying areas of employment were patient interactions, intellectual stimulation, interactions with colleagues, and work schedule. The least satisfying areas were work schedule and financial compensation. Training was felt to be too focused on female factor infertility and basic research with insufficient training on embryology, genetics, male factor infertility, and clinical research. In the next 5years, 57% suggested that the need for specialists would stay the same, while 20% predicted a decrease. A total of 58% felt we are training the correct number of fellows (37% felt we are training a surplus). Compared with academia, those in private practice reported higher compensation, less major surgery, more IVF, less endocrinology, and less research. Men worked more hours, conducted more surgery and IVF cycles, and had higher compensation than women. Morale was similar across age, gender, practice type, and geography.Our subspecialty has an extremely high morale. We are a middle-aged subspecialty with disparate compensation and a focused practice. Some respondents sense a need for a change in our training, and most anticipate only mild growth in our field.

Hormonal and Nonhormonal Treatment of Vasomotor Symptoms OBSTETRICS AND GYNECOLOGY CLINICS OF NORTH AMERICA Krause, M. S., Nakajima, S. T. 2015; 42 (1): 163-?

Abstract

This article focuses on the cause, pathophysiology, differential diagnosis of, and treatment options for vasomotor symptoms. In addition, it summarizes important points for health care providers caring for perimenopausal and postmenopausal women with regard to health maintenance, osteoporosis, cardiovascular disease, and vaginal atrophy. Treatment options for hot flashes with variable effectiveness include systemic hormone therapy (estrogen/progestogen), nonhormonal pharmacologic therapies (selective serotonin reuptake inhibitors, selective norepinephrine reuptake inhibitors, clonidine, gabapentin), and nonpharmacologic therapy options (behavioral changes, acupuncture). Risks and benefits as well as contraindications for hormone therapy are further discussed.
