Despite the extensive research on the consequences of migration, little is known about the effects of seasonal migration on fertility, contraception and sexually transmitted diseases in the countries of former Soviet Union, that have undergone vast demographic changes in the last two decades. Using cross-sectional data from two surveys conducted in Armenia in 2005 and 2007, this dissertation is exploring the effects of seasonal migration on reproductive behavior and outcomes, as well as sexual health among women left-behind. The dissertation is constructed of three independent studies that combined draw the broad picture of the consequences of seasonal migration in this part of the world. The first study, "Seasonal migration and fertility in low-fertility areas of origin" looks at the effect of seasonal migration on yearly pregnancy rates, lifetime fertility, and fertility preferences among women and their husbands. The models are fitted using discrete-time logistic regression, and random-intercept logistic regression for negative binomial and binary outcomes, correspondingly. The findings show that seasonal migration in low-fertility settings does not further disrupt fertility levels in a short-, or long-run, contradicting to the findings from high-fertility settings. However, the study provides some evidence that seasonal migration is associated with increased fertility preferences among migrant men. The second study, "Seasonal migration and contraception among women left-behind", examines the associations between migration and modern contraceptive use, by looking at current contraceptive use and the history of abortions. A series of random-intercept logistic regression models reveal that women with migrant partners are significantly less likely to use modern contraceptives, than women married to non-migrants. They also have higher rates of abortions; however this effect is moderated by the socioeconomic status of the household. The third study, "Seasonal migration and risks of sexually transmitted diseases (STDs) among women left-behind", looks at the effects of seasonal migration on the diagnosed STDs in the last three years, and self reported STD-like symptoms in the last twelve months. The results of random-intercept logistic regression for negative binomial and binary outcomes provide strong evidence of increased STD risks among migrants' wives; however, this effect is also moderated by the household income.

One out of ten women has a difficult time getting or staying pregnant in the United States. Recent studies have identified aging as one of the key factors attributed to a decline in female reproductive health. Existing fertility diagnostic methods do not allow for the non-invasive monitoring of hormone levels across time. In recent years, olfactory sensing has emerged as a promising diagnostic tool for its potential for real-time, non-invasive monitoring. This technology has been proven promising in the areas of oncology, diabetes, and neurological disorders. Little work, however, has addressed the use of olfactory sensing with respect to female fertility. In this work, we perform a study on ten healthy female subjects to determine the volatile signature in biological samples across 28 days, correlating to fertility hormones. Volatile organic compounds (VOCs) present in the air above the biological sample, or headspace, were collected by solid phase microextraction (SPME), using a 50/30 µm divinylbenzene/carboxen/polydimethylsiloxane (DVB/CAR/PDMS) coated fiber. Samples were analyzed, using comprehensive two-dimensional gas chromatography-time-of-flight mass spectrometry (GC×GC-TOFMS). A regression model was used to identify key analytes, corresponding to the fertility hormones estrogen and progesterone. Results indicate shifts in volatile signatures in biological samples across the 28 days, relevant to hormonal changes. Further work includes evaluating metabolic changes in volatile hormone expression as an early indicator of declining fertility, so women may one day be able to monitor their reproductive health in real-time as they age.

David Wildt's cheetah (Acinonyx jubatus) research from 1978-1983 became the foundation for the use of embryological techniques in endangered species breeding programs. The cheetah is a member of the cat family (Felidae), which includes thirty-seven species. According to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) all Felidae species are currently threatened or endangered, with the exception of the domestic cat (Felinus catus). Cheetahs are an internationally recognized charismatic megafauna species, prized zoo specimens, difficult to breed, and the basis of many conservation campaigns. Like most species, cheetahs have not traditionally been studied; only a few "model" organisms have been thoroughly researched in a laboratory setting. This research revealed that the difficulty observed in breeding cheetahs in captivity is due to their lack of genetic diversity.

The herbal compound was invented by Lydia Estes Pinkham in 1873 in her home kitchen in Lynn, Massachusetts. Pinkham created the compound by mixing alcohol with roots and herbs. The compound was patented, packaged, and distributed by the Mrs. Lydia Pinkham Medicine Company in 1876. The Mrs. Lydia Pinkham Medicine Company advertised the compound in many US newspapers and magazines, causing Lydia Pinkham’s Vegetable Compound to become a household name and making treatments for female reproductive discomfort mainstream in the US.

In Jeter v. Mayo, the Court of Appeals of Arizona in 2005 held that a cryopreserved, three-day-old pre-embryo is not a person for purposes of Arizona's wrongful death statutes, and that the Arizona Legislature was best suited to decide whether to expand the law to include cryopreserved pre-embryos. The Court of Appeals affirmed a decision by the Maricopa County Superior Court to dismiss a couple's wrongful death claim after the Mayo Clinic (Mayo) allegedly lost or destroyed several of their cryopreserved pre-embryos. In reaching its decision, the Court of Appeals explored ethical and legal issues relating to cryopreserved pre-embryos, including prior case law, the principles of statutory construction, and the Arizona Legislature's role in balancing the societal interests involved.

Lydia Estes Pinkham invented and sold Lydia Pinkham’s Vegetable Compound, a medicinal tonic used to treat menstrual discomfort and promote female reproductive health in general, in the US during the nineteenth century. Pinkham also founded Mrs. Lydia E. Pinkham Medicine Company, a business that sold natural remedies for women’s health issues. Throughout her life, Pinkham acted as an authority on female wellness, writing medical pamphlets about female anatomy and reproductive processes. In those pamphlets, Pinkham addressed female medical issues that physicians did not frequently discuss with their patients. Pinkham’s advertising techniques and her products helped women learn about their reproductive anatomy and processes and helped ease menstruation.

In 2017, Julie Carré, Nicolas Gatimel, Jessika Moreau, Jean Parinaud, and Roger Léandri published “Does Air Pollution Play a Role in Infertility?: a Systematic Review,” hereafter “Does Air Pollution Play a Role,” in the journal Environmental Health. The authors completed a systematic literature review to investigate the effects of air pollutants on fertility in exposed populations. Since air quality has an impact on overall health as well as on reproductive function, the authors sought to increase the awareness of the importance of environmental protection issues among the general public and the authorities. The article “Does Air Pollution Play a Role” provided the foundation for further research on how air pollution can contribute to low reproductive capacity in areas with high exposure.

Throughout history many different methods have been devised for the early detection of pregnancy. From the time of the Ancient Egyptians, inspection of the urine has been a popular place to start. However, it was not until the discovery of hormones in the early twentieth century that the development of truly reliable pregnancy tests occurred. Prior to 1978, when the first home pregnancy tests became available in the United States, pregnancy testing was done in hospital laboratories using various methods, one of them being the Aschheim-Zondek, or A-Z test.
