human reproduction class 12

There are also stories about how different animals' reproduction has inspired research in human reproduction. For instance, some animals have unique ways of ensuring successful fertilization that scientists study to gain insights for improving human fertility treatments.

In some cases, couples with a family history of genetic diseases have benefited from PGS testing. For example, a couple knew they were carriers of a certain genetic disorder. Through PGS, they could identify and choose embryos that were free from that genetic defect. This led to the birth of healthy children, giving them a chance to start a family without the constant worry of passing on the disease.

One success story could be a couple who had been trying to conceive for years. They underwent fertility treatments, and finally, through in - vitro fertilization, the sperm successfully met the egg in a laboratory setting. The embryo was then transferred to the mother's womb, and she gave birth to a healthy baby.

Yes. There are instances where a 5 - cell embryo was transferred during an IVF cycle and led to a successful pregnancy. The embryo's development potential was carefully assessed, and despite being at the 5 - cell stage, it had the necessary genetic integrity and cytoplasmic factors to implant and grow.

There are also cases of natural conception where the woman has only one fertilized egg in a cycle. This can be due to various factors like age or hormonal imbalances. However, with a healthy lifestyle, proper nutrition, and regular prenatal check - ups, that single fertilized egg can develop successfully. For example, a woman who is older and has a lower ovarian reserve may still have a successful pregnancy with that one fertilized egg if she takes good care of herself during pregnancy. This includes eating a balanced diet, getting enough rest, and following the doctor's advice.

Sure. There are cases where women with hormonal imbalances had successful in vitro maturation. Their immature eggs were retrieved and then matured in the laboratory. These matured eggs were then fertilized and implanted, resulting in successful pregnancies. This shows that in vitro maturation can be an alternative for those who may not respond well to traditional IVF methods.

The cultivation techniques of begonia flowers included sowing, cutting, and splitting. The sowing method was suitable for April to May in spring and August to September in autumn. The seeds were evenly scattered on the fine mud in the pot without covering with soil. Then, they could germinate after 10 days by watering them with the water absorption method at the bottom of the pot. The cutting method could be carried out throughout the year, but there were fewer branches after the seedling was formed, so it was generally not commonly used. The splitting method was suitable for old perennials. They could be split and trimmed to promote new side branches to form a complete plant shape. During reproduction, attention should be paid to the control of pests and diseases. Common diseases include powder mildews and bacteria wilt.
