Genes in His Jeans] [Molly Kane] James Madison University Lexia Volume V 2
Lexia: Undergraduate Journal in Writing, Rhetoric & Technical Communication Volume V 2016–2017 [Genes in his Jeans] [Molly Kane] James Madison University Lexia Volume V 2 If you asked women who were considering sperm donation what their ideal donor was like, you would probably receive answers like “smart,” “kind,” “tall,” and “healthy” (“What Women Want”). They would want their donor to be the perfect man, so that they would have the perfect child. Now imagine someone who you would see going to a clinic to donate their sperm. Is that man a fit and handsome stock broker, right off Wall Street, or is he a poor college student with bad acne looking to make some extra cash? To say the least, sperm donors span all walks of life. Women flip through hundreds of applications when trying to choose which donor will be the father of her child, and only general information is given to her about each donor. It is hard to imagine how one of the biggest decisions of her life will be based off which self-proclaimed personality traits she likes best. One of the greatest concerns when selecting a sperm sample is the state of health of the donor. Every mother wants a healthy baby, and in order for this to happen with donor-conceived children, both the mother and father need to be healthy individuals. You would assume that sperm banks only accept donors with a thorough health history and health risk evaluation, and you would probably also assume that they require tests for life-threatening diseases, such as cystic fibrosis. -
A Study of Bioethical Qualifiers in the Donation of Human Sperm
Intersect, Vol 14, No 2 (2021) Creating Boundaries in the Sperm Donation Industry: A Study of Bioethical Qualifiers in the Donation of Human Sperm Tanvee Sinha1 1 The University of Alabama at Birmingham While sperm donation has become a common and effective practice amongst many who suffer from the inability to conceive naturally, the practice's bioethical implications may reveal a necessity to place qualifying constrictions on the practice. Some examples of related ethical issues range from psychological impacts on offspring as a result of partial genetic dissociation from parents, and discriminatory practices, such as “shopping” for traits or narrow descriptions of optimal sperm donors. Regulations for eligible donors vary in different regions, while keeping some sort of uniformity through criteria, including height, weight, education, and lifestyle choices. This piece highlights some of the major cultural differences between China and the USA in regard to the regulation of sperm donation. Recently in China, after the “one- child only” policy was lifted, there is an increasing demand for sperm donors now than ever, but with new policies, it is even more difficult to donate and purchase sperm. Due to donors not being able to qualify for the “amount of patriotism” needed, there is an increased use of underground operations, such as the black market. These operations are often unsafe and have no regulation, encouraged by donors and middlemen solely seeking monetary value. Sinha, Boundaries in Sperm Donation Background In the twentieth century, there has been a rapid advancement in technology, causing numerous innovative ways for one to now have a child. -
Male Infertility
www.livestrong.org.livestrong.org Male Infertility Some male cancer survivors find that they are not able to have children due to the effects of cancer treatment. By identifying your risk for infertility, you can take steps before treatment to preserve your fertility. For survivors who have already completed treatment, there are other options for having children. Male Infertility: Detailed Information This infinformationormation is meant to be a general introduction to this topic. The purpose is to provide a starting point for you to become more informed about important matters that may be affecting your life as a survivor and to provide ideas about steps you can take to learn more. This information is not intended nor should it be interpreted as providing professional medical, legal and financial advice. You should consult a trained professional for more information. Please read the Suggestions (http://www.livestrong.org/Get-Help/Learn-About-Cancer/Cancer-Support-Topics/Physical-Effects-of- Cancer/Male-Infertility#a#a) and Additional Resources (http://www.livestrong.org/Get-Help/Learn- About-Cancer/Cancer-Support-Topics/Physical-Effects-of-Cancer/Male-Infertility#a#a) sections for questions to ask and for more resources. Cancer and treatment may put survivors at risk for infertility. Male infertility generally means an inability to produce healthy sperm or to ejaculate sperm. There are many different causes of infertility in cancer survivors including physical and emotional. Certain treatments can cause or contribute to this condition. It is best to discuss the risks of infertility with your doctor before cancer treatment begins. However, there are options for survivors who experience infertility as a result of cancer or treatment. -
Evolution of Oviductal Gestation in Amphibians MARVALEE H
THE JOURNAL OF EXPERIMENTAL ZOOLOGY 266394-413 (1993) Evolution of Oviductal Gestation in Amphibians MARVALEE H. WAKE Department of Integrative Biology and Museum of Vertebrate Zoology, University of California,Berkeley, California 94720 ABSTRACT Oviductal retention of developing embryos, with provision for maternal nutrition after yolk is exhausted (viviparity) and maintenance through metamorphosis, has evolved indepen- dently in each of the three living orders of amphibians, the Anura (frogs and toads), the Urodela (salamanders and newts), and the Gymnophiona (caecilians). In anurans and urodeles obligate vivi- parity is very rare (less than 1%of species); a few additional species retain the developing young, but nutrition is yolk-dependent (ovoviviparity) and, at least in salamanders, the young may be born be- fore metamorphosis is complete. However, in caecilians probably the majority of the approximately 170 species are viviparous, and none are ovoviviparous. All of the amphibians that retain their young oviductally practice internal fertilization; the mechanism is cloaca1 apposition in frogs, spermato- phore reception in salamanders, and intromission in caecilians. Internal fertilization is a necessary but not sufficient exaptation (sensu Gould and Vrba: Paleobiology 8:4-15, ’82) for viviparity. The sala- manders and all but one of the frogs that are oviductal developers live at high altitudes and are subject to rigorous climatic variables; hence, it has been suggested that cold might be a “selection pressure” for the evolution of egg retention. However, one frog and all the live-bearing caecilians are tropical low to middle elevation inhabitants, so factors other than cold are implicated in the evolu- tion of live-bearing. -

Women's Menstrual Cycles
1 Women’s Menstrual Cycles About once each month during her reproductive years, a woman has a few days when a bloody fluid leaves her womb and passes through her vagina and out of her body. This normal monthly bleeding is called menstruation, or a menstrual period. Because the same pattern happens each month, it is called the menstrual cycle. Most women bleed every 28 days. But some bleed as often as every 20 days or as seldom as every 45 days. Uterus (womb) A woman’s ovaries release an egg once a month. If it is Ovary fertilized she may become pregnant. If not, her monthly bleeding will happen. Vagina Menstruation is a normal part of women’s lives. Knowing how the menstrual cycle affects the body and the ways menstruation changes over a woman’s lifetime can let you know when you are pregnant, and help you detect and prevent health problems. Also, many family planning methods work best when women and men know more about the menstrual cycle (see Family Planning). 17 December 2015 NEW WHERE THERE IS NO DOCTOR: ADVANCE CHAPTERS 2 CHAPTER 24: WOMEN’S MENSTRUAL CYCLES Hormones and the menstrual cycle In women, the hormones estrogen and progesterone are produced mostly in the ovaries, and the amount of each one changes throughout the monthly cycle. During the first half of the cycle, the ovaries make mostly estrogen, which causes the lining of the womb to thicken with blood and tissue. The body makes the lining so a baby would have a soft nest to grow in if the woman became pregnant that month. -

The ancestors of modern humans who invented food processing (including cooking) gained critical advantages in survival and fitness through increased caloric intake. However, the time and manner in which food processing became biologically significant is uncertain. Here, we assess the inferred evolutionary consequences of food processing in the human lineage by applying a Bayesian phylogenetic outlier test to the first comparative analysis of feeding time in humans and non-human primates. -

Here we investigated if the acrosomal status of the processed semen preparations used at a fertility clinic can also be informative and whether it is associated with fecundity. The acrosomal status was measured by image cytometry on purified semen samples from couples during in vitro fertilization (IVF) (n = 99) and intracytoplasmic sperm injection (ICSI) (n = 107) treatment. -

Donor INSEMINATION Insemination
CLiInSemBrochure_CryoGenicInSemBrochure 12/14/10 12:28 PM Page 1 DONOR Donor INSEMINATION Insemination Donor insemination (DI) is a simple procedure that uses a syringe to place sperm into a woman’s vagina or uterus to assist her in becoming pregnant. The sperm is obtained from someone other than a woman’s husband or partner. Sperm banks (also known as cryobanks) offer a selection of screened and tested sperm donors for those interested in using DI. Your physician will discuss which DI procedure is right for you. There are basically two types of insemination options: intrauterine or intracervical. • INTRAUTERINE INSEMINATION: Semen is inserted directly into the uterus, by way of the cervical opening, using a small catheter. The sperm specimen is labeled as IUI (intrauterine) and is pre-washed, meaning that seminal plasma is removed prior to freezing. • INTRACERVICAL INSEMINATION: Semen is placed into the cervical opening. Sperm is typically labeled as ICI (intracervical or standard) and is unwashed, i.e. the seminal plasma has not been removed. WHY CHOOSE DI? There are several advantages to using DI over other methods: • Donor selection can be made with the participation of your husband or partner. • The woman can experience pregnancy and all the excite - ment, anticipation and bonding derived from carrying and delivering her child. This brochure is the courtesy of • As a mother, you will know that your child is produced from your own eggs and your own genetic material. Donor Insemination (DI) is widely • By attending the inseminations, the husband or partner can practiced throughout the world with an share in the child’s conception. -
