Good evening,
I am attempting a stimulated FET cycle after an unsuccessful HRT (lining ended up going backwards to 5.6mm despite E2 being over 1800). Lining is always trilameter and RE has concluded no lining defects. I suspect the cancelled HRT was due to lack of blood flow.
Instead of trying the CCRM thin lining protocol, I’m trying the stim FET because my lining has been between 9 and 11mm on my 5 previous ivf cycles.
I am adding pentoxifylline 400mg 2xday and Vitamin E to the stim cycle. Can I administer the pentoxifylline vaginally, as recommended for Viagra? Could Viagra be added near the end of stims if lining is not quite thick enough- how many days needed on Viagra to make a difference?
My RE is willing to transfer at 7.5mm or above- the clinic’s standard is 8mm or above. I see you recommend 9mm or above as optimal, and between 8-9mm mediocre. Should I settle for 7.5? I only have 3 viable (PGS) embryos and don’t want to take any risks.
Thanks for your time, Dr. Sher!
I personally would not transfer to a uterus that at the time of progesterone has a lining <8mm. Pentoxifyline is hit and miss! Viagra is administered from the beginning of stimulation.
About seventeen years ago, after reporting on the benefit of vaginal Sildenafil (Viagra) for to women who had implantation dysfunction due to thin endometrial linings I was proud to announce the birth of the world’s first “Viagra baby.” For those of you who aren’t familiar with the use of Viagra in IVF, allow me to provide some context.
It was as far back as 1989, when I first published a study that examined the correlation between the thickness of a woman’s uterine lining (the endometrium), and the subsequent successful implantation of embryos in IVF patients. This study revealed that when the uterine lining measured <8mm in thickness by the day of the “hCG trigger” (in fresh IVF cycles), or at the time of initiating progesterone therapy (in embryo recipient cycles, e.g. frozen embryo transfers, egg donation-IVF etc.) , pregnancy and birth rates were substantially improved. Currently, it is my opinion, that an ideal estrogen-promoted endometrial lining should ideally measure at least 9mm in thickness and that an endometrial lining measuring 8-9mm is “intermediate”. An estrogenic lining of <8mm is in most cases unlikely to yield a viable pregnancy.
A “poor” uterine lining is usually the result of the innermost layer of endometrium (the basal or germinal endometrium from which endometrium grows) ) not being able to respond to estrogen by propagating an outer, “functional” layer thick enough to support optimal embryo implantation and development of a healthy placenta (placentation). The “functional” layer ultimately comprises 2/3 of the full endometrial thickness and is the layer that sheds with menstruation in the event that no pregnancy occurs.
The main causes of a “poor” uterine lining are:
1.Damage to the basal endometrium as a result of:
a.Inflammation of the endometrium (endometritis) most commonly resulting from infected products left over following abortion, miscarriage or birth
b.Surgical trauma due to traumatic uterine scraping, (i.e. due to an over-aggressive D & C)
2.Insensitivity of the basal endometrium to estrogen due to:
a.Prolonged , over-use/misuse of clomiphene citrate
b.Prenatal exposure to diethylstilbestrol (DES). This is a drug that was given to pregnant women in the 1960’s to help prevent miscarriage
3.Over-exposure of the uterine lining to ovarian male hormones (mainly testosterone): Older women, women with diminished ovarian reserve (poor responders) and women with polycystic ovarian syndrome -PCOS tend to have raised LH biological activity.. This causes the connective tissue in the ovary (stroma/theca) to overproduce testosterone. The effect can be further exaggerated when certain methods for ovarian stimulation such as agonist (Lupron/Buserelin) “flare” protocols and high dosages of menotropins such as Menopur are used in such cases.
4.Reduced blood flow to the basal endometrium:
Examples include;
a.Multiple uterine fibroids - especially when these are present under the endometrium (submucosal)
b.Uterine adenomyosis (excessive, abnormal invasion of the uterine muscle by endometrial glands).
“The Viagra Connection”
Treatments such supplementary estrogen therapy, aspirin administration and/or administration of high dosage gonadotropin fertility drugs, aimed at improving endometrial development have all yielded disappointing results.
It was in the 90’s that Sildenafil (brand named Viagra) was gaining popularity as a treatment for erectile dysfunction. The mechanism by which it acted was through increasing penile blood flow through increasing nitric oxide activity. This prompted me to investigate whether Viagra administered vaginally, might similarly improve uterine blood flow and in the process cause more estrogen to be delivered to the basal endometrium and thereby increase endometrial thickening. We found that when Viagra was administered vaginally it did just that! However oral administration was without any significant benefit in this regard. We enlisted the services of a compound pharmacy to produce vaginal Viagra suppositories. Initially, four (4) women with chronic histories of poor endometrial development and failure to conceive following several advanced fertility treatments were evaluated for a period of 4-6 weeks and then underwent IVF with concomitant Viagra therapy. Viagra suppositories were administered four times daily for 8-11 days and were discontinued 5-7 days prior to embryo transfer in all cases.
Our findings clearly demonstrated that vaginal Viagra produced a rapid and profound improvement in uterine blood flow and that was followed by enhanced endometrial development in all four cases. Three (3) of the four women subsequently conceived. . I expanded the trial in 2002 and became the first to report on the administration of vaginal Viagra to 105 women with repeated IVF failure due to persistently thin endometrial linings. All of the women had experienced at least two (2) prior IVF failures attributed to intractably thin uterine linings. About 70% of these women responded to treatment with Viagra suppositories with a marked improvement in endometrial thickness. Forty five percent (45%) achieved live births following a single cycle of IVF treatment with Viagra The miscarriage rate was 9%. None of the women who had failed to show an improvement in endometrial thickness following Viagra treatment achieved viable pregnancies.
Following vaginal administration, Viagra is rapidly absorbed and quickly reaches the uterine blood system in high concentrations. Thereupon it dilutes out as it is absorbed into the systemic circulation. This probably explains why treatment is virtually devoid of systemic side effects
Since the introduction of this form of treatment, thousands of women with thin uterine linings have been reported treated and many have gone on to have babies after repeated prior IVF failure.
It is important to recognize that Viagra will NOT be effective in improving endometrial thickness in all cases. In fact, about one third of women treated fail to show any improvement. This is because in certain cases of thin uterine linings, the basal endometrium will have been permanently damaged and left unresponsive to estrogen. This happens in cases of severe endometrial damage due mainly to post-pregnancy endometritis (inflammation), chronic granulomatous inflammation due to uterine tuberculosis (hardly ever seen in the United States) and following extensive surgical injury to the basal endometrium (as sometimes occurs following over-zealous D&C’s).
To be effective, Viagra must be administered vaginally. It is NOT effective when taken orally. We prescribe 20mg vaginal suppositories to be inserted four times per day. Treatment is commenced soon after menstruation ceases and is continued until the day of the “hCG trigger.” While ideally the treatment should be sustained throughout the first half of the cycle, most women will respond within 48-72 hours. For this reason, Viagra can be used to “rescue” a poor lining after the cycle has already started, provided that there is enough time remaining prior to ovulation, egg retrieval or progesterone administration.
Good luck!

Hello doc keep up the good work….please i have had two surgeries already due to ectopic pregnancy.I recently went for IVF and during the preliminary test,they discovered i have ovarian cyst on the right hand side.I was told they cant proceed with the process except i go for a surgery to remove the cyst or use a egg donor.I would love to use my egg.please kindly advice on this
I strongly suggest we talk!

Hey,
First of all, thank you so much for your open blog,
I am 35 years old Male and 29 years spouse. we have one baby girl and looking to have a baby boy.
My couple of questions are
– Is there any simpler way to get gender selection using IUI. if yes, could you please advise me you do and what’s the method you follow with complete details. If you are doing means, could you please advise me which clinics in USA does?
– Is IVF or other advanced Technics helps?
Thank you so much for your time and quicker reply in advance,
Regards,
Raj
Hi Raj,
The older methods to try and establish gender bias through sperm washing have all fallen inyto discredit. The only way is through IVF with genetic embryo selection.
Couples have for centuries sought to influence the gender of their offspring. More than seven centuries ago the ancient Chinese developed a birth calendar said to be able to predict gender on the basis of when conception occurred. Later, the ancient Greeks suggested that by lying on her right side during intercourse, a woman could improve the likelihood of having a male child. And 300 years ago, the French suggested that placing a ligature around the right testicle would improve the chance of having a male child.
More recently in the U.S., methods such as timing intercourse, assuming different positions during sex, and (relatively recently) employing rapid sperm centrifugation in an attempt to separate male chromosome-bearing sperm from female sperm prior to artificial insemination were proposed. The fact is that none of these (as well as many other) such anecdotal assertions have been shown to have any real validity.
Currently, in spite of several well described medical approaches, the indisputable fact has emerged that it is only by way of IVF that reliable sex selection can be achieved. This allows for embryos to be screened for gender through preimplantation genetic diagnosis prior to transferring the embryo(s) of the desired gender to the uterus.
Nevertheless, it is an inescapable reality that the very idea of medical sex selection challenges moral and ethical beliefs at their very foundation. Many hold that the growing popularity of gender selection solely for the convenience of altering a family’s gender balance represents an unwanted example of how assisted reproductive technology is subject to abuse…and thus it should be outlawed. They also see it as an example of a disturbing trend towards “designer babies” where genetic engineering could be used to manipulate the intellect, body configuration, build, height, and the talents of future offspring. This assertion is commonly followed by the tantalizing question as to where all this would end and whether we as a society “would really want to live in such a world.”
There is, however, one clear exception to the apparent across-the-board opposition to sex selection that is well worthy of mention. This applies in cases where sex selection is used to avoid the occurrence of a serious medical disorder that selectively affects one gender or the other (e.g., Hemophilia, a life threatening bleeding disorder that selectively affects male offspring).
EVALUATING CURRENTLY USED METHODS FOR SEX SELECTION
SPERM GRADIENT METODOLOGY (discredited because of a lack of reliability)
This is one of the simplest methods that still (unfortunately) remains in widespread use. Here sperm is rapidly spun down (centrifuged) in the hope of separating the male sperm (those with Y-chromosomes) from the female sperm (those with X-chromosomes). It relies on the assumption that the X chromosome makes sperm heavier, allowing for separation of male from female chromosome-bearing sperm. Though this method is often touted as a low cost method for sex selection, the truth is that it simply does not work!
LOW CYTOMETRIC TESTING BY THE MICROSORT METHOD (discredited because of a lack of reliability)
This method which is now somewhat discredited by the FDA employedthe use of a fluorescent dye that adheres to genetic material within the sperm. It was based on the premise that because X-bearing sperm contain more genetic material, these sperm were supposed to pick up more dye than Y-bearing sperm. Thereupon, X and Y bearing sperm are then separated into two groups and used for intrauterine insemination (IUI) or IVF. This method was touted as yielding a 60% to 70% accuracy rate with IUI. This has not been adequately confirmed and in my personal experience its reliability in the IVF setting has been questionable to say the least. The Microsort technique is to my knowledge not presently being offered in the United States.
IVF using PREIMPLANTATION GENETIC DIAGNOSIS (PGD)
Preimplantation Genetic Diagnosis (PGD) involves the removal of one or more cells from an embryo, for chromosomal or genetic analysis. The most widely used and he most reliable PGD method for gender selection is fluorescence in-situ-hybridization (FISH). However, this technique does not identify all 23 pairs of chromosomes in the embryo’s cells. At best it can well identify 12. Thus, while FISH provides an excellent method for gender selection and for identification of structural chromosomal aberrations, it is not a reliable method for diagnosing embryo aneuploidy (“competency”). Conversely, another PGD method, next generation gene sequencing (NGS) which does assess all the embryo’s chromosomes can be used for both detecting all the embryo’s chromosomes and thus can determine embryo “competency” reliably. It also reliably identifies gender. However, while NGS is very bit as reliable as FISH for gender selection, FISH can be done in fresh cycles (i.e. the ET is done in the same cycle as that in which the ER is done), while NGS requires time for testing that requires Staggered IVF (St-IVF) in which the embryos are biopsied on day 3 or day 5-6 (post-fertilization) and the blastocysts are ultrarapidly frozen (vitrified) and allowed to proceed in culture to blastocysts whereupon they are ultra-rapidly frozen (vitrified) and are then held for transfer in a subsequent cycle.
Upon completion of FISH, which takes about 24-36 hours, the couple can select which embryo(s) they will transfer to the uterus. If pregnancy results, there is almost a 100% chance it will result in the desired gender. If NGS is used, the degree of accuracy in diagnosing gender, is as reliable as is FISH but in addition, NGS provides information on the entire karyotype (all 23 pairs of chromosomes) which is extremely beneficial because it assesses embryo “competency, while FISH does not.
A PERSONAL OPINION:
Sex selection done purely for family balancing is somewhat controversial, raising concern that if widely accessible and freely available, such practice could distort the natural sex ratio, leading to a population gender imbalance. However, for this to happen, there would have to be a significant population preference for sex selection. In reality, the contrary seems to apply, since studies conducted in western societies discount these concerns. In fact, the relatively high cost of IVF with the added cost of gender selection in the United States makes it unlikely that the demand would ever become large enough to impact overall population gender balance. In addition, several studies done in Western countries have shown that the majority of people do not seem to be concerned about the gender of their offspring, and that with a few notable exceptions, gender preference does not appear to be slanted in the direction of either male or female. Thus, from a practical standpoint, such concerns are overstated.
Given that in the United States most couples do not care about the gender of their offspring, and only a minority are interested in selecting the sex of their children there is currently no risk that IVF sex-selection will impact the population gender balance. Thus, in my opinion by and large, freedom of choice should prevail and a service for sex selection should be freely available
So, in my personal practice, I absolutely do offer gender selection in the following circumstances.
•Medical Indications for Gender Selection:
oFor cases associated with
?sex-linked genetic disorders or,
?serious genetic disorders that are more likely to occur in one gender or the other.
•Non-Medical Family balancing
o For couples who have at least one child of the opposite gender to that which they choose for their IVF embryo transfer and,
oFor those women who do not have any children at all but prefer to have a child of one or the other gender.

Hi Dr Sher, I know the optimum minimum measurement of the lining for transfer is 8/9cm, but I wondered if there was a maximum measurement, for when it is too thick and transfer should not be performed? Thank you
In the absence of uterine/endometrial pathology, there is no such thing as an overthick uterine lining.
Geoff Sher
FET non medicated with progesterone starting evening after trigger. 7.3 lining “beautiful” they say, day of trigger shot.
Does the lining get thicker after trigger up until transfer? Is this too thin for a viable pregnancy?
Thanks!
In my opinion, the endometrial thickness needs to be at least 8mmm at the time of the “trigger. Any thickening after that is NOT due to increase in cell numbers but due to progesterone-induced secretion into endometrial glands and is not part of the equation.
