QUESTION:
Why is Sasmar Conceive Plus™ being attacked by a competitor?
ANSWER:
See our response here: "Pre~Seed
attacks Conceive Plus"
The inventor of Pre~Seed continues to make false claims against
Sasmar Conceive Plus with "self funded" "scientific
studies" that show our product negatively. We are not sure what
formula is being used in these studies but it is not one produced
and released by us. We can only assume that the motive of this
anti-competitive behavior is the increasing loss of sales, as
Sasmar Conceive Plus expands distribution around the world taking
their market share.
The Conceive Plus formulation is scientifically proven, safe and in our studies (both internal and external) produce results that are far superior to all products produced by the competition. We could release damaging data (some is publically avaiable if you search for it) about this particular competitor, but we choose not to. Maybe that will change in the future.
QUESTION:
Is Pre Conceive Plus (Pre-Conceive Plus) the same as Sasmar Conceive Plus?
ANSWER:
NO. The formulation of "Pre Conceive Plus" is NOT the same as Sasmar Conceive Plus. The product previously sold in the USA under the name Pre-Conceive Plus was not manufactured by SASMAR and the formula of the two products are different, the pH is different and the Osmolarity is also different. There should be no confusion between Pre Conceive Plus and Sasmar Conceive Plus.
So what is the story with the rights to Pre-Conceive Plus? - There was a legal battle about confidentiality between the manufacturers of Pre Conceive Plus and pre-seed (ING Fertility). The legal battle ended with this manufacturer of Pre-Conceive Plus giving pre-seed the rights over stock of Pre Conceive Plus (NOT SASMAR CONCEIVE PLUS). The owners of SASMAR have never met or had any correspondence with the manufacturers of Pre-Conceive Plus.
Sasmar Conceive Plus should not be confused with pre-seed, pre', Pre Conceive Plus or any other product.
Important note: The owners of pre-seed publish false and misleading information about Sasmar Conceive Plus with self funded "scientific studies" (unethical?) to scare consumers into thinking that pre~seed is the only personal lubricant that is safe to use. Sasmar Conceive Plus is scientifically proven, developed by scientists (Harvard Medical School, Massachusetts General Hospital, Emmanuel College Boston, Miller School of Medicine, University of Miami) with studies published by the American Society of Reproductive Medicine.
QUESTION:
Why do some lubricants harm chances of conception and pregnancy? How does Sasmar Conceive Plus™ help one’s path to pregnancy?
ANSWER:
A number of clinical studies have shown that commercially available contraceptive Personal lubricants are spermicidal (harmful to human sperm) (see references below). Such personal lubricants harm sperm viability and/or motility, thereby decreasing or eliminating the chances of conception and, thus, pregnancy. Sasmar Conceive Plus™ is very different. It has been scientifically formulated to not harm sperm viability or function, thereby improving your chances of conception or pregnancy.

QUESTION:
Isn’t Glycerol naturally present in human cervical fluid and isn't it harmful to sperm?
ANSWER:
Glycerol is a natural ingredient of human cervical fluid (see
Huggins et al. 1976, Preti et al. 1979, Huggins et al. 1981, Owen
et al. 1999 below). In fact, studies have shown that the amount
of glycerol in cervical fluid increases during sexual excitement
(Preti et al. 1979). This increase in glycerol has been postulated
to be responsible for the lubricating quality of this fertile
cervical fluid and may be biologically relevant during the early
phase of reproductive events (Huggins et al. 1981). Sasmar Conceive
Plus™ contains small amounts of glycerol in order to better mimic
the natural fertile cervical fluids.
Glycerol is also a source of energy and is naturally present in
our body. Glycerol also preserves cells and has been extensively
used in cryopreservation of human sperm and eggs. Because of its
exceptional cryopreservation properties, glycerol has ben extensively
studied for its effects on the viability and function of many
human cells and tissue. It is currently one of the most commonly
and extensively used cryoprotectant.
There are several scientific studies showing that small amount
of glycerol (which is naturally present in human cervical mucus,
as described above) has no negative impact on sperm viability
and function. For example, a widely cited study by Tulandi et
al. showed that addition of glycerol to human semen at concentrations
as high as 2% of semen had no significant affect sperm function
(see Figure 1). Similarly, another study by Goldenberg et al.
showed that glycerol had no significant effect on human sperm
motility, whereas other known spermicidal lubricants (such as
K-Y, Lubifax and Ortho-Gynol) completely immobilized the human
sperm. Yet another scientific study, by Critser et al., showed
that presence of glycerol at concentrations as high as 5% and
had no significant effect on human sperm motility even after 24h
of incubation (see Figure 2).
Figure 1. Effect of glycerol on Sperm Motility and Progression (adapted from Tulandi et al, 1984). It clearly shows that addition of glycerol to human semen at concentrations as high as 2% of semen has no significant affect on sperm function.
Figure 2. Effect of glycerol on Sperm Motility (adapted from Crister et al, 1988). It clearly shows that incubation of human sperm with concentrations of glycerol as high as 5% has no significant affect on sperm function, even after 24h of incubation. (0% is control)

QUESTION:
What is the importance of calcium and magnesium ions?
ANSWER:
Calcium and Magnesium ions are naturally present in all bodily
fluids and cells, including in human semen and in cervical fluids,
as illustrated in several scientific studies, some of which are
referenced below. Presence of calcium in human semen was shown
as early as 1942 in a landmark study by Huggins et al. Calcium
and magnesium are critically important for the viability and function
of sperm and eggs. For example, a scientific study with 143 men
by Adamopoulos et al. showed that, “Ca concentration in asthenozoospermic
and oligozoospermic patients was lower than in normozoospermic
men and was positively correlated with Mg concentration irrespectively
of seminal quality or the presence of infection”. Similarly, sperm
also has an absolute requirement for calcium ions in order to
undergo acrosome reaction in preparation for egg fertilization
(see Evans et al. review).
Sasmar Conceive Plus™ is the ONLY formulation that contains these
important ingredients.

QUESTION:
What is the pH of Sasmar Conceive Plus™?
ANSWER:
The pH of Sasmar Conceive Plus™ is 7.5. To survive and function, human sperm requires an environment that contains certain electrolytes and is within a narrow range of pH, osmolality and tonicity. The World Health Organisation (see references below) has reported that the optimal condition for sperm survival and migration in the cervical mucus requires a pH in the range of 7.0 to 8.5 and an isotonic solution. Sasmar Conceive Plus™ is carefully formulated so that both pH and osmolality are at levels which are safe for sperm.

QUESTION:
What is the osmolarity of Sasmar Conceive Plus™?
ANSWER:
The osmolarity of Sasmar Conceive Plus™ is close to 357mOsmol/L.
Sasmar Conceive Plus™ is designed to be within the measured physiologic
osmolarity range of 290-423mOsmol/L that is optimal for sperm
survival and migration in the cervical mucus (see Owen et al.
below). As described above, in order to survive and function,
human sperm requires an environment that contains certain electrolytes
and is within a narrow range of pH, osmolality and tonicity. There
is considerable debate in literature, and little agreement among
physicians and scientists, about the exact osmolarity range for
human semen, cervical fluid and the environment that is optimal
for conception and fertility in humans.
Among many published scientific reports, a widely cited study
by Anderson et al. see below), comparing measured osmolality of
various lubricant solutions and the effect of each of these lubricant
solutions on human sperm motility, showed that a lubricant solution
with osmolarity of 422 ± 4.1 mosmol/L was not harmful to sperm,
whereas a different lubricant solution with much lower osmolality
of 298 ± 8.8 mosmol/L) was harmful. A prediction based on merely
measuring the osmolality of these two solutions would have lead
to an exactly opposite result! It is also important to mention
that experiments by Anderson et al. were performed under conditions
mimicking in vivo coital conditions, where it is known that the
total time of contact between sperm and lubricant typically lasts
between 5-30 min, after which time most of the seminal fluid is
discarded in backflow.

QUESTION:
Does Sasmar Conceive Plus™ contain any surfactants, like Pluronic?
ANSWER:
No. Surfactants are typically formulated in spermicidal lubricants. Surfactants are also used to solubilize water-insoluble ingredients in water. One scientific study (Kurtz et al, 2002) showed that the presence of surfactant Pluronic 127 was harmful to sperm, although more studies are needed to confirm and fully validate this finding. As Sasmar Conceive Plus™ is scientifically formulated to not harm sperm, it does not contain any surfactant.

QUESTION:
Does Sasmar Conceive Plus™ contain any harmful acidic polymers?
ANSWER:
No. Acrylic acid derived polymers, such as Carbomer, are acidic and are one of the key ingredients of spermicidal lubricants, such a BufferGel (see references below) that reduce the chance of conception and pregnancy.

QUESTION:
Is Sasmar Conceive Plus™ safe for sperm and embryo development?
ANSWER:
YES. The Conceive Plus formula has been developed in conjuction
with experts from respected, leading USA university hospitals
and and is proven to be safe for sperm and embryo development.
Extensive studies have been carried out on Conceive Plus (including
different production batches made in both our France and Australian
factories). Recently some of our studies were published by the
American Society for Reproductive Medicine and you can see the
actual RESULTS of the studies under "The
Science" tab.

QUESTION:
Is Sasmar Conceive Plus™ the only commercially available sperm-safe lubricant for couples trying-to-conceive?
ANSWER:
Probably not. Internet search reveals that there are several
other non-spermicidal lubricants now available for sale online.
However, we strongly believe that Sasmar Conceive Plus™ most closely
mimics the fertile natural environment as it exclusively contains
the Calcium and Magnesium ions that are naturally present in fertile
human cervical fluids and are critical for sperm viability and
function.

Note To All Our Readers:
Please be aware of the concept of “The marketing of fear” (see
Selling sickness: the pharmaceutical industry and disease mongering,
BMJ 2002; 324: 886) as you research the various lubricants available.
It often includes instilling fear about a disease, condition or
drug (or ingredients) in the name of “awareness” using selected
scientific data that only supports their own point of view and
then offering/selling the only perfect solution to cure the “fear”.
As there are no absolutes in science and medicine, always be skeptical
of online advice that sounds like the “final word” (see “The
logic of scientific discovery” by Sir Karl Popper, Basic Books,
New York, 1959).
