Simply put: We must talk prevention versus treatment of this health condition, which is not inevitable. On the present large scale, impaired fertility is anthropogenic – where anthropogenic means “caused or produced by humans”. When trying to conceive, it is highly advisable not to delay baby making beyond the optimal age of early 20s, and in any case to practice “focused intercourse”. In that connection (with said focus), “anthropogenic” acquires a positive connotation – even if my introduction is no longer exactly simply put!
The said focus on focused intercourse is an absolute must, and you save yourself a lot of grief that way because there can be no conception outside of the fertile window, whether subfertile or not. This should really be in your mind and in your heart when you are trying to conceive. And if you are, unfortunately, past the optimal age of early twenties, just try and don’t delay pregnancy any longer – for a good reason (or rather for several good reasons)!
To expand on this, let the scene be set by excerpts from a review in a medical journal written already 10 years ago by a consultant in reproductive medicine (director of an assisted conception unit in London): “ABC of subfertility. Extent of the problem”, BMJ 2003 August 23; 327(7412): 434–436 (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC188498/).
QUOTE: One in six couples [17%] have an unwanted delay in conception. Roughly half of these couples will conceive either spontaneously or with relatively simple advice or treatment.
Most couples presenting with a fertility problem do not have absolute infertility (that is, no chance of conception), but rather relative subfertility with a reduced chance of conception… so that only 4% remain involuntarily childless. As each couple has a substantial chance of conceiving without treatment, relating the potential benefit of treatment to their chances of conceiving naturally is important… END QUOTE.
This is rather encouraging, isn’t it? The cited reproductive medicine specialist states further that spontaneous conception has about a 30% conception rate in the first month of trying, and the chance then falls steadily to about 5% by the end of the first year. Such statistical pronouncements are just that. The following citation is unarguably meaningful – and we do not gloss over the “timing of intercourse during the natural cycle”.
“The likelihood of spontaneous conception is affected by [= is dependent on] age, previous pregnancy, duration of subfertility, timing of intercourse during the natural cycle, extremes of body mass, and [any] pathology present. A reasonably high spontaneous pregnancy rate still occurs even after the first year of trying. A strong association exists between subfertility and increasing female age. The reduction in fertility is greatest in women in their late 30s and early 40s. For women aged 35-39 years the chance of conceiving spontaneously is about half that of women aged 19-26 years.” QUOTE UNQUOTE.
These things have been covered in the various earlier posts of this blog, with appropriate emphasis on said timing of intercourse during the natural menstrual cycle. That’s because, even if you did have a previous pregnancy and you do NOT have an extreme body mass and/or a pathology causing the difficulty to get pregnant, you (and anyone else) can only conceive during the short fertile period, the so-called fertile window.
And, I go again as far as urging you, “Be a young mother!” As I said, this earnest recommendation is for a good reason. Because, in addition to what I have told you about before (e.g. in http://biozhena.wordpress.com/2012/04/18/the-perils-of-ivf-of-arts-of-giving-birth-at-old-age-part-2/ ), now see and grasp this:
Serious health consequences of delayed conception are beginning to appear in medical literature; that is, serious consequences for the mother, for the would-be mum.
For example, in a paper titled “Subfertility and risk of later life maternal cardiovascular disease” published in Hum. Reprod. 2012 Feb;27(2):568-75 (http://www.ncbi.nlm.nih.gov/pubmed/22131387). The authors gave this background: “Subfertility shares common pathways with cardiovascular disease (CVD), including polycystic ovarian syndrome [PCOS], obesity and thyroid disorders. Women with prior no or just one pregnancy are at an increased risk of incident CVD when compared with women with two pregnancies.”
They concluded that subfertility among women who eventually have a childbirth is a risk factor for cardiovascular disease. As if we all did not know that even without subfertility adding to it, heart disease is the leading cause of death among women [see http://www.health.harvard.edu/newsweek/Gender_matters_Heart_disease_risk_in_women.htm or literally millions of other web pages].
But there is not just the cardiovascular risk, as if that were not enough! Concerns about cancer risk in connection with subfertility have been raised in medical literature already about a decade ago, such as in the paper “Cancer risk associated with subfertility and ovulation induction: a review” – published in Cancer Causes Control 2000 Apr;11(4):319-44 (http://www.ncbi.nlm.nih.gov/pubmed/10843444).
However, there “the only consistent association observed is an increased risk of endometrial cancer for women with subfertility due to hormonal disorders. While positive findings in some studies on fertility drugs and ovarian cancer risk have aroused serious concern, the associations observed in most of these reports appear to be due to bias or chance rather than being causal.”
So, as always, more investigations are needed but the health concern does not go away. The paper concluded: “To discriminate between the possible carcinogenic effects of various ovulation induction regimens, subfertility disorders, and reproductive characteristics associated with subfertility, future studies should include large populations of subfertile women with sufficient follow-up time.”
Well, the truth is that my purpose – and the purpose of bioZhena Corporation – is to make the population of subfertile women as small as possible, by helping every one of you to determine the very narrow fertile window for your “focused intercourse”, the fundamental requirement for getting pregnant.
This fundamental requirement you already know, I trust. If not, explore the bioZhena’s Weblog for clarification (you can use Table of Contents at http://biozhena.wordpress.com/table-of-contents-links-to-biozhena-posts/ or try searching the blog by means of the widget in the margin on the home page, shown as Search bioZhena’s Weblog – enter keyword, hit Enter). It is frustrating that one of my recent blog pieces had to be on the subject of only the best that you can do for your fertility awareness in the absence of the Ovulona™ – because our Ovulona is not yet available to you due to our lack of financing (see http://biozhena.wordpress.com/2012/12/14/end-of-the-year-and-trying-to-get-pregnant/ ).
Meanwhile, here is another medical-literature paper, this time about cancer risk of drugs that the healthcare industry uses to help women get pregnant – after helping women to prevent pregnancy with another (the big P) drug, the anthropogenic cause of what experts have called the epidemic of impaired fertility: “Ovulation inducing agents and cancer risk: review of literature” published in Curr Drug Saf. 2011 Sep 1;6(4):250-8 (find the abstract at http://www.ncbi.nlm.nih.gov/pubmed/22129320).
The authors give the following summary: “Over the past decades, the use of ovulation inducing drugs has been increasing. A possible causal link between fertility treatments (especially [the widely used] clomiphene citrate and gonadotrophins) and various types of malignancies, including cancers of female reproductive system, thyroid cancer and melanoma, has been postulated. The majority of the available studies on this subject suffer from methodological limitations, including the small number of outcomes, short and incomplete follow-up, and inability to control for potential confounders.
Concerning ovarian cancer, while early studies led to the suggestion of an association between ovulation inducing agents and increased risk of malignancies, the majority of data do not support a causal link.
An increased risk was recently observed in women giving birth after in vitro fertilization (IVF), but it appeared to be consequential to the infertile status rather than the effect of fertility drugs. More controversial are the results concerning breast cancer with some investigations suggesting an increased risk after exposure to ovulation inducing agents, especially clomiphene citrate, whereas others not supporting this concept. A possible trend towards an increased risk has been reported by some authors for endometrial cancer.
Altogether, current data should be thus regarded as a signal for the need of further studies rather than being definitive in them.” END QUOTE.
I must emphasize and impress on you the fact that subfertility and infertility became a societal problem of increasingly large proportions only after the introduction of the anti-conception Pill. “After 3 and up to 15 months of contraceptive pill use, there is a greater loss of the S crypt cells than can be replaced.” The S crypts of the endocervical canal are needed for conception.
To further cite Professor Erik Odeblad : “Complications arising from the use of the Pill are very frequent. Infertility after its use for 7-15 years is a very serious problem. S crypts are very sensitive to normal and cyclical stimulation by natural estrogens, and the Pill causes atrophy of these crypts. Fertility is impaired since the movement of sperm cells up the canal is reduced. Treatment is difficult.”
You can find more on this in my earlier post, Difficult to conceive – Google evidence that pregnancy complications and trying-to-conceive concerns shot up after the Pill launch in 1960s. (Regardless of what contraceptive proponents tell you.)
I am reminded of an insight expressed on the floor of the US Congress after the Pill made a big impact on society in the 1960s. In 1970, Dr. Hugh J. Davies of Johns Hopkins University told the US Senate in the Nelson Hearings about the contraceptive Pill: “Never before in history have so many people taken such powerful medication with so little information as to its actual and potential risks. …With the introduction of such active ingredients, we are actually setting up a massive endocrinological experiment with millions of healthy women.”
Well, decades later we are reaping the consequences of the massive experiment. Said millions of healthy women are not quite so healthy, are they? It is high time to fix this man-made problem.
