What is Estrogel made from?

Are synthetic conjugated horse oestrogens like Premarin and bioidentical oestrogen like progesterone different?

Unfortunately, when the results of the study were publicised, no distinction was made between synthetic conjugated horse oestrogens like Premarin and bioidentical oestrogen and progesterone.

Why can’t we use HRT on pregnant mares?

Firstly, drugs containing CEEs are not well tolerated by the human body and the Premarin family of HRT increases the risk of suffering from thrombosis or a heart attack or breast cancer. And secondly, treatment of the pregnant mares is very cruel.

Is horse urine natural estrogen?

It’s natural in that it’s made from plant sources, but it’s not bio-identical to human estrogens. Instead, as a conjugated estrogen, it’s the plant-based copy of Premarin. It’s not horse urine, like estrogen, but the estrogens in it are copies of equine estrogens.

Which estrogens are natural HRT?

• Natural estrogens include: Estrace, Estratab, Ogen, the estradiol patches such as Climara, Alora, Vivelle, Estraderm, Esclim, FemPatch, etc, Tri-Est What about Phytoestrogens? Aren’t they considered Natural HRT?

How do you check a horse’s uterus for pregnancy?

A veterinarian can perform a transrectal palpation 16 to 19 days after the mare has been with a stallion. The vet puts his or her hand in the mare’s rectum to check the uterus for indications of pregnancy.

How to take care of a horse in the third trimester?

Walk your mare for 15 mins 2-3 times a day during the third trimester. A paddock or pasture is the best place to walk your mare. Gently lead her at her own pace, as she’s likely to walk slowly since the foal is getting big. It’s also okay to let her self-exercise, as long as she’s in a familiar paddock or pasture.

Is Premarin equine estrogen?

Premarin is horse estrogen! It is derived from the urine of pregnant mares, hence, its brand name. Premarin works great in female horses, just as Chevy parts work great in Chevys. But replacing human estrogens with horse estrogens may be asking for trouble, and here’s why.

What is the difference between reproductive hormones in horses and humans?

The difference in reproductive hormones is just one of many differences between horses and humans. You may have noticed that horses also have four hooves and a mane, whereas human females don’t.

Does horse urine cause strokes?

“The Journal of the American Medical Association reports that women treated with Premarin (estrogens derived from horse urine, Wyeth) alone were 39% more likely to have a stroke during a 7-year follow-up period in the Women’s Health Initiative, compared to women treated with placebo.

Can we replace human estrogens with horse estrogens?

But replacing human estrogens with horse estrogens may be asking for trouble, and here’s why. For the last several million years, the human female reproductive system has been running quite well on three separate estrogens: estriol, estrone, and estradiol, which occur in an approximate ratio of 90%:3%:7% 1 (Fig. 1).

What are natural forms of HRT?

What are Natural Forms of HRT? In most discussions of HRT, “natural” refers to estrogens and progesterone that are often man-made, but from natural plant sources. Most of them are naturally occurring and in theory, bio-identical to the hormones your body makes.

Do humans have estrogen like mares?

The estrogen in you is identical to the estrogen in your mare, at least for the three estrogens that humans have: estradiol, estriol, and estrone. Note that Premarin (the synthetic drug many doctors still prescribe to menopausal woman) is a conjugated estrogen product made from pregnant mares’ urine.

How many types of estrogens do horses have?

Luckily mares usually only have estrus 6-7 months out of the year! Humans have only three types of estrogens, whereas horses have over 20 types. The molecular structure of any natural steroid hormone is exactly the same or nearly the same in humans as it is in animals and most plants.

How do you know if a horse is pregnant?

Experienced equine veterinarians can feel a mechanical bulge in a mare’s uterus by Day 30 to 35 of gestation. Typical intervals for checking mares are: Day 14 to 16 – confirms initial pregnancy and looks for twins. Day 26 to 30 – confirms heartbeat and fact that fetus is alive.

How do you do a urine test for pregnancy in horses?

A urine test can be performed by a veterinarian or using a home test. Obtain a home pregnancy testing kit from a feed store or online.

Use the bottom to collect your mare’s urine.

How do vets check a horse’s uterus?

Transrectal palpation – This normally takes place between 16 and 20 days after the horse has been covered and involves a veterinarian putting their hand up the mare’s rectum to check the size and shape of the uterus as well as check the ovaries for any swelling.

Can you feel a horse’s embryo in the uterus?

Alternatively, a veterinarian may be able to manually feel the small embryo in the mare’s uterus approximately six weeks into the pregnancy via rectal palpation. It’s important to have the mare checked by a veterinarian early in the pregnancy for her health and the health of her foal. Horse twins are rare but can lead to the mare aborting.

What should I Feed my mare during her third trimester?

You may also need to add a feed supplement (vitamin and mineral supplement) to ensure that all of her nutritional requirements are being met. The third, and final trimester for your mare runs from day 226 until around day 340 – the average foaling date.

When is my mare’s third trimester?

The third, and final trimester for your mare runs from day 226 until around day 340 – the average foaling date. This trimester is undisputedly the most important trimester in terms of fetal growth and development.

How to maintain a pregnant horse during the first trimester?

During the first trimester, her nutritional requirements will be basically the same as they were before she became pregnant. To ensure that your mare maintains a healthy weight, she can be maintained on high-quality forage, pasture or hay and unlimited access to a mineral salt block.

How did Premarin get its name?

The Premarin family of drugs contains estrogenic compounds that are made from the urine of pregnant mares. That’s where the name is derived from: PREgnant MAres’ urINe = Premarin.

What is Premarin for horses?

Premarin is available in several forms (pills, creams, injections, patches) and, as the name (a shortening of the phrase “pregnant mares’ urine”) suggests, contains conjugated estrogens obtained from the urine of pregnant mares.

Can Premarin mares walk?

Premarin mares are not allowed to move, walk or run, which is natural for them – or graze on grass and frolic in a pasture which is normal behavior for horses, because the urine collection device is attached to them 24/7.

Do horses have hormones?

Chorionic tissues in horses as well as primates also form hormones. eCG is formed in foetal endocrine cells and is found within the maternal circulation. eCG is thought to play a similar role in horses to hCG in primates in terms of pregnancy recognition. Foetal production of eCG is highest between 30-70 days of pregnancy.

What is the menstrual cycle in horses?

Women have menstrual cycles that are about 5-7 days long and horses have their estrous cycle for about 5 days,but usually only from April through September. The hormonal cycle is thus quite similar for humans as for horses. FSH (follicle stimulating hormone) causes the production of estrogen and promotes maturation of the follicle.
