Athletes or people with a fair amount of muscle mass may be over this ideal range, which is why the metric can be misleading, but again, it’s a good general guide to consider for the majority of the population.
What is the purpose of IVF?
In vitro fertilization (IVF) is a complex series of procedures used to help with fertility or prevent genetic problems and assist with the conception of a child. During IVF, mature eggs are collected (retrieved) from ovaries and fertilized by sperm in a lab. Then the fertilized egg (embryo) or eggs (embryos) are transferred to a uterus.
How many cells are in an embryo after fertilization?
Three days after fertilization, a normally developing embryo will contain about six to 10 cells. By the fifth or sixth day, the fertilized egg is known as a blastocyst — a rapidly dividing ball of cells. The inner group of cells will become the embryo. The outer group will become the cells that nourish and protect it.
What causes fewer eggs to be fertilized?
Fallopian tube damage or blockage makes it difficult for an egg to be fertilized or for an embryo to travel to the uterus. Ovulation disorders. If ovulation is infrequent or absent, fewer eggs are available for fertilization. Endometriosis.

Portion Size
It is very common for people to eat more than they need. Ideally, our dietary intake should match our physical activity levels to keep our weight in balance. If you used to exercise every day and stopped, you have to eat less. Some clients report a habit of finishing each meal despite the portion size due to how they were brought up.
Snacks
The number of snacks you need a day is individual. But please think about why you snack? If you are hungry all the time, make sure your meals are balanced and contain a fair amount of protein and vegetables and slow absorbing carbohydrates. Examples of slow absorbing carbohydrates are listed below:
Meal Pattern
I think there is still no consensus on the number of meals we should eat a day. However, it is a well-known fact that irregular eating is unhealthy and may contribute to weight gain. Therefore, I recommend eating within an hour or two from the time you wake up. Keep the gaps between meals to a maximum of 5-6 hours.
Cooking Methods
Think about how much oil or butter you are using when preparing your meals. I usually suggest sticking to a teaspoon of oil or butter per person as a guide. A similar rule applies to sauces and dressings. However, it depends on whether you are using a full or low-fat variety. Remember to limit regular mayonnaise to a teaspoon.
Eating Out and Takeaway Food
I think that an occasional restaurant meal or a takeaway now and again will not cause any harm. However, regular takeaway/convenience food consumption may cause weight gain and boost the intake of salt and unhealthy fats. Limit yourself to a maximum of one takeaway/restaurant meal a week. This can also help to save some pennies.
Desserts
Have you got a sweet tooth? Please don’t worry because it is still possible to lose weight. Try making your own desserts. Measure ingredients carefully. Whenever possible, use low-calorie substitutes, e.g. natural sweeteners, low-fat yoghurt, chia seeds, and plant-based kinds of milk.
Eating When Not Hungry
Many people turn to food when stressed or bored. However, if you want to lose weight efficiently, every time you get an urge to have something to eat, ask yourself whether you really need it? Try a drink first, especially if it’s late at night.

Do obese women need gonadotrophins?
Obese women (i.e. with a BMI of 30 or more) often require higher doses of gonadotrophins (always a risk). They may respond less well to ovarian stimulation and produce fewer eggs. Embryos can be lower quality. Fertilisation rates are lower. And miscarriages sadly happen more often.
