The New York Times (Aug. 16, 2017): Sperm Count in Western Men Has Dropped Over 50 Percent Since 1973, Paper Finds, by Maya Salam
The sperm count of men in Western countries has been declining precipitously with no signs of “leveling off,” according to new research, bolstering a school of thought that male health in the modern world is at risk, possibly threatening fertility.
By examining thousands of studies and conducting a meta-analysis of 185 — the most comprehensive effort to date — an international team of researchers ultimately looked at semen samples from 42,935 men from 50 countries from 1973 to 2011.
They found that sperm concentration — the number of sperm per milliliter of semen — had declined each year, amounting to a 52.4 percent total decline, in men from North America, Europe, Australia and New Zealand.
Possible causes that researchers have identified include exposure to cigarette smoke, alcohol, and chemicals--such as phthalates--in utero. Age, obesity, and stress also play a role in lowered sperm count and quality. While long-term consequences have yet to be identified, research shows that fertility rates in Western nations are too low to sustain the current population.

New York Times (Apr. 8, 2016): Fathered by the Mailman? It's Mostly an Urban Legend, by Carl Zimmer:
Stories about adultery and uncertainty about paternity permeate mass media and popular culture. At the dawn of the era of DNA testing, some data suggested that up to 30% of the children born to married couples were the product of adultery. But those data involved requests by husbands who suspected their wives had extramarital paramours. New research suggests that births of children from wives' adulterous liaisons actually occurs very seldom.
The new study looks at inheritance of the Y chromosome. The Y chromosome is passed down in almost identical form from fathers to sons. By studying the chromosomes of living related men in various countries (Spain, Italy, Germany, Mali and Belgium), researchers came up with an adulterous paternity rate of less than one percent.
One reflection of the low rate may lie in the inefficacy of human sperm to compete for fertilization as compared to other species'. "The only way for men to have evolved comparatively ineffectual sperm," according to one researcher, "was for them to have experienced high rates of paternity over time." She added that better assurances of paternity lead to higher investments of fathers in their children. These investments have been critical to the survival of the species given that humans are completely helpless when they are born.

Jezebel: Floyd Mayweather Posts Ex's Sonogram, Accuses Her of 'Killing Babies', by Erin Gloria Ryan:
Earlier this year, boxer Floyd Mayweather got dumped by his fiancee Shantel Jackson after he allegedly cheated on her. But Mayweather has since apparently gone batshit insane, insisting that it was he who dumped her, and that he did it because she had "a abortion." To support this accusation, he posted what he claims are images from a sonogram Jackson had in December. Holy shit.
Mayweather posted the images — complete with identifying details and measurements, which we've blurred out — to Facebook this morning . . . .

Study Finds that Men's "Biological Clock" Means Higher Risk of Mental Illness in Children Born to Older Fathers
The New York Times: Mental Illness Risk Higher for Children of Older Fathers, Study Finds, by Benedict Carey:
Children born to middle-aged men are more likely than those born to younger fathers to develop any of a range of mental difficulties, including attention deficits, bipolar disorder, autism and schizophrenia, according to the most comprehensive study to date of paternal age and offspring mental health. . . .
. . . Men have a biological clock of sorts because of random mutations in sperm over time, the report suggests, and the risks associated with later fatherhood may be higher than previously thought. The findings were published on Wednesday in the journal JAMA Psychiatry. . . .

Salon: The 10 strangest facts about penises, by Tracy Clark-Flory:
Simone de Beauvoir called it “a small person … an alter ego usually more sly … and more clever than the individual.” Leonardo da Vinci said it “has dealings with human intelligence and sometimes displays an intelligence of its own.” Sophocles said that having one was to be “chained to a madman.”
These great thinkers were referring so exasperatedly, so powerlessly, to none other than the penis. That’s a lot of hype for a body part that can “be seen as something the Creator doodled in an idle moment,” as Tom Hickman puts it in the new book, “God’s Doodle: The Life and Times of the Penis.” . . .

The Los Angeles Times - op-ed: Assisted reproduction: When does a father become one?, by Naomi Cahn & June Carbone:
A bill in the California Senate would add to uncertainty about parenthood in cases of donated sperm.
When does a man become a father — the legally recognized parent of a child, responsible for support and eligible for custody? Historically, parenthood has involved something more than simply a biological connection. In some eras that meant the law recognized only fathers who married the mothers. Today, recognition extends to unmarried parents who raise a child together.
The new question on the table is whether it extends to a man who donates sperm to a woman and establishes a relationship with the child. . . .

The Guardian UK: Why I Support Women's Access to Safe, Legal Abortion, by Rob Delaney:
I so love my kids, I can be envious of my wife for carrying them when pregnant. But I care about her right to choose just as much
I support a woman's right to safe, legal abortion because centuries of history shows us that women are going to get abortion whether they are safe and legal or not. And when they're not safe and legal, these women will often die terrible or be damaged irreparably. . . .

The New York Times - Well blog: A Different Kind of Fatherhood, by David Tuller:
I came out long before gay men yearned for weddings, much less baby showers. In 1979, when I was 22, New York offered young men like me many freedoms, including the freedom to not have to propagate. Like many other gay men — and like many straight men — I had not been close to my own father. I could not imagine wiping runny noses, attending parent-teacher conferences or playing Candy Land.
In my 30s I moved to San Francisco and, to my surprise, found myself contemplating parenthood. . . .

I. Glenn Cohen and Travis G. Coan (both of Harvard Law School) have posted Can You Buy Sperm Donor Identification? An Experiment. Here is the abstract:
In the United States, most sperm donations are anonymous. By contrast, many developed nations require sperm donors to be identified, typically requiring new sperm (and egg) donors to put identifying information into a registry that is made available to a donor-conceived child once they reach the age of 18. Recently, advocates have pressed U.S. states to adopt these registries as well, and state legislatures have indicated openness to the idea. This study re-lies on a self-selected convenience sample to experimentally examine the economic implications of adopting a mandatory sperm donor identification regime in the U.S. Our results support the hypothesis that subjects in the treatment (non-anonymity) condition need to be paid significantly more, on average, to donate their sperm. When restricting our attention to only those subjects that would ever actually consider donating sperm, we find that individuals in the control condition are willing-to-accept an average of $$43 to donate, while individuals in the treatment group are willing-to-accept an aver-age of $74. These estimates suggest that it would cost roughly $31 per sperm donation, at least in our sample, to require donors to be identified. This price differential roughly corresponds to that of a major U.S. sperm bank that operates both an anonymous and identify release programs in terms of what they pay donors.

The Los Angeles Times - op-ed: A birth control double standard, by Meg Waite Clayton:
Condoms are readily available without identification. Why not Plan B?
In the uproar about making the morning-after contraceptive known as Plan B available to our daughters, there has been no similar outcry about condoms and our sons. Anyone of any age can walk into a drugstore — as well as most grocery and big-box stores — and buy condoms. . . .

The current attention to the “end of men” is occurring as men’s role as biological fathers is becoming radically deemphasized through assisted reproductive technologies and alternative family formation. As other historians have noted, since the nineteenth century, there have been serial crises of masculinity in the United States, in which the perceived loss of power by white middle-class heterosexual men has been decried. This essay, written for an on-line forum considering Hanna Rosin's The End of Men, analyzes the current crisis in the context of earlier explorations of the biological end of men, from early twentieth century feminist utopian fiction to lesbian dreams of virgin birth in the 1970s.

Medical News Today: Reproductive Coercion Common in Abusive Relationships, by Kelly Fitzgerald:
Adolescent girls and women should now be screened for reproductive coercion, a form of abuse that occurs when male partners sabotage their contraception intentionally.
This form of abuse, known as reproductive coercion, can manifest in several ways, such as deliberately giving a partner a sexually transmitted disease (STIs), forcing a partner to have an undesired abortion or pregnancy, or seizing control of a woman's contraceptive pills. . . .

The New York Times op-ed: Men, Who Needs Them?, by Greg Hampikian:
Mammals are named after their defining characteristic, the glands capable of sustaining a life for years after birth — glands that are functional only in the female. And yet while the term “mammal” is based on an objective analysis of shared traits, the genus name for human beings, Homo, reflects an 18th-century masculine bias in science.
That bias, however, is becoming harder to sustain, as men become less relevant to both reproduction and parenting. Women aren’t just becoming men’s equals. It’s increasingly clear that “mankind” itself is a gross misnomer: an uninterrupted, intimate and essential maternal connection defines our species. . . .

Salon.com: Stop our sperm, please, by Irin Carmon:
Meet the men who want better male birth control -- and want it badly
Lenny Smalls, whose Facebook page says he lives in Chicago and works as a transportation analyst, is very interested in long-acting, reversible male contraception. According to his posts on a fan page for one form being tested — known as RISUG or Vasalgel — Smalls is sufficiently frustrated by the pace of such drugs coming to the U.S. market to have begun personally testing an Indonesian herbal product called gandarusa. . . .

NPR Health blog: In Protest, Democrats Zero In On Men's Reproductive Health, by Teresa Tomassoni:
For perhaps the first time in recent history, male reproductive health is at the forefront of political debate.
In at least six states, lawmakers — all women and all Democrats — have proposed bills or amendments in the last few weeks that aim to regulate a man's access to reproductive health care. It's their way of responding to the ongoing debate around contraception and abortion, said Jennifer Lawless, director of the Women & Politics Institute at American University.
Some would prohibit men from getting vasectomies, such as Georgia's House Bill 1116, which states:
"Thousands of children are deprived of birth in this state every year because of the lack of state regulation over vasectomies.". . .
